Last year again demonstrated the kind of global challenges infection research is confronted with. The unusual

magnitude and spread of the still ongoing Ebola epidemic in West Africa required concerted international action plans

to contain the disease. In September 2014, the WHO declared the Ebola epidemic to be “out of control”.

During this crisis, the DZIF was able to prove its strength: in March 2014, our physicians and scientists from Hamburg,

Marburg and Munich were already on the ground in Africa to establish viral diagnostics and to help the people

affected. Furthermore, a research consortium to tackle Ebola – EBOKON – was established within the shortest time

under the leadership of the DZIF research field “Emerging Infections”, and was generously supported with further

federal funding. A definite highlight was the DZIF’s participation in clinical trials for a vaccine against the Ebola virus

in Hamburg and Lambaréné.

Over the last year, antibiotic-resistant pathogenic bacteria returned to the public spotlight, and the DZIF network

accomplished internationally acknowledged success here as well. With teixobactin and cystobactamides, DZIF

scientists have identified new active agents which have the potential to form a new generation of antibiotics. Product

development now needs to be expedited in collaboration with the industry.

After longstanding research work, the research goals for HIV and viral hepatitis are on the verge of a change of

paradigm: new active agents have made chronic hepatitis C a curable disease. The DZIF partner sites have made

significant contributions to this development and testing. This development raises hopes that other chronic infections

such as hepatitis B and HIV infection may also be cured.

We hope these examples have inspired you to continue reading. The Annual Report illustrates the DZIF’s broad range

of translational research approaches, including the latest diagnosis, prevention and treatment approaches of MERS

coronavirus, HIV, malaria and tuberculosis.

United against infections: group photo at the DZIF Annual Meeting 2014.

Infectious diseases remain a major challenge in medi-

cine, even in the 21st century. How can we stop the

spread of pathogens? Which new treatment approa-

ches work? What should we do when pathogens be-

come insensitive to antibiotics? Researchers at the

German Center for Infection Research (DZIF) try to

answer these questions, and others. They develop

new drugs, vaccines, and preventive measures against

infectious diseases.

The German Center for Infection Research is a re-

search association, organised virtually, with an affiliation

of a total of 35 establishments at seven partner sites.

Around 250 scientists work together across the diffe-

rent partner sites in Germany. Under the motto “Uni-

ted against infections”, they contribute their expertise

to developing new agents against infectious diseases.

DZIF research activities are strategically planned and

aligned to accomplish this from the start.

The DZIF is one of six German Centers for Health Re-

search (DZG) established by the German Federal Minis-

try of Education and Research (BMBF). The fundamental

goal of this initiative is to fight widespread diseases more

effectively. The DZIF started its work under the umbrella

of this alliance in 2012. Financing is 90 percent from fede-

ral funds and 10 percent from participating federal states´

funds.

Organised across the sites

All researchers have the infrastructures and compe-

tencies of the existing establishments at their disposal.

DZIF partner sites include: Bonn-Cologne, Gießen-

Marburg-Langen, Hamburg-Lübeck-Borstel, Hannover-

Braunschweig, Heidelberg, Munich und Tübingen. DZIF

research institutes, universities, hospitals and federal

research institutes collaborate across the sites. Basic re-

search, epidemiology and clinical research are promoted

equally.

Aligning translation

The DZIF aims to close existing gaps between basic re-

search and clinical applications. Research is governed by

the practical needs of the patient. To this effect, the DZIF

promotes a rapid transfer of research results from bench

to bedside (translation). Well-structured collaboration be-

tween researchers, medical doctors, probands and patients

ensures smooth operating procedures. In doing so, patients

benefit faster from the improvements made to diagnosis,

prophylaxis and treatment of infectious diseases.

Structured thematically

The DZIF is divided into nine research fields. In each field,

specialised scientists at the different partner sites de-

dicate themselves to working on a pathogen or specific

issue in infection research. The research fields are called

“Emerging Infections”, “Tuberculosis”, “Malaria”, “HIV”,

“Hepatitis”, “Gastrointestinal Infections”, “Infections of

the immunocompromised Host”, “Healthcare-associated

and Antibiotic-resistant bacterial Infections”, and “Novel

Antiinfectives”.

Supportive infrastructure

Moreover, the DZIF has established its own infrastruc-

tures important to its research. These comprise specialised

services which are available to all members and provide

support. Here, for example, information is collected for

subsequent processing, and important patient samples or

natural substances are stored for later testing. Advice is

provided for difficult processes, and further training for

next-generation talents. Also, contacts can be made to

establishments all over the world.

Collaborating internationally

Numerous collaborations with external scientific in-

stitutions and the industry strengthen the DZIF’s position

as a top-class institution for infection research. In addition,

it has international partner sites, for example in Africa and

Eastern Europe. In this way, infectious diseases which are

rare in Germany, such as malaria, Ebola and tuberculosis,

can be researched where they occur frequently. These

contacts and collaborations are critical to the DZIF for ta-

king on the global challenges in infection research.

DZIF groups its research activities into nine re-

search fields and six research infrastructures –

internally called Thematic Translational Units (TTUs)

and Translational Infrastructures (TIs):

“We have survived”: An impressive thank you to all Ebola helpers on the ground, including those from the DZIF.

Numerous new pathogens have emerged over the

last 40 years, causing diseases such as AIDS, avian in-

fluenza and Ebola. In the era of global mobility, viruses

and bacteria also know no boundaries. For this reason,

DZIF researchers in the field “Emerging Infections” often

have to react swiftly to stop the spread of unknown

pathogens. In order to achieve this, scientists from re-

search institutes, hospitals and public health services

work closely together.

DZIF researchers focus on characterising pathogens rapid-

ly, developing new drugs and vaccines, as well as epidemio-

logical investigations. The reason for this is that emerging

infectious diseases, like Ebola, can be curbed more effec-

tively, the earlier the pathogen and its routes of spread are

identified. On several occasions, DZIF researchers discov-

ered that some pathogens are transmitted from animals to

humans. Avian influenza and Ebola belong to this group of

pathogens. They cause diseases termed zoonoses and are

responsible for around three quarters of all emerging in-

fections. They often originate from viruses that have been

transmitted from wild animals to humans.

Better prepared for unexpected outbreaks

In this context, DZIF scientists investigated the evolutio-

nary biology of the hepatitis C virus which causes severe

inflammation of the liver in humans. “We want to under-

stand where the hepatitis C virus comes from,” explains

Prof Jan Felix Drexler from the Institute of Virology of

the University of Bonn. Together with colleagues from

Hamburg, Hannover, Ghana and Moscow, his team re-

cently discovered novel viruses that are distantly related to

the hepatitis C virus. The researchers found them in cattle

which they investigated at the DZIF partner institution in

In Ghanaian cattle, researchers discovered new viruses that aredistantly related to hepatitis C viruses.

Ghana. Just like the hepatitis C virus, these newly discov-

ered novel viruses belong to the group of hepaciviruses.

However, Drexler is certain,

no person with hepatitis C

infection contracted the vi-

rus from cows—the genetic

differences are too large.

Nevertheless, this discovery

allows for important insights

into the evolution of hepaci-

viruses. In general: “Only

when you know whether a human virus actually origina-

ted from animals, can you react to future outbreaks and

work towards eradicating certain viruses,” says Drexler.

Ebola virus epidemic: rapid reaction in emergencies

The Ebola virus, first described in 1976, could be con-

tained quickly with quarantine measures in all previous

outbreaks. However, the 2014 epidemic in West Africa,

reached unforeseen dimensions of cases and deaths. Re-

searchers worldwide searched for ways to fight the epi-

demic, in which patients presented symptoms of fever,

vomiting, diarrhoea and internal bleeding, often ending

in death. An international expert consortium, led by the

WHO, selected a promising candidate vaccine on which

to conduct further trials. DZIF researchers were also

involved with the first clinical trial in humans. At the

University Medical Center Hamburg-Eppendorf (UKE),

in Switzerland, Gabon and Kenya, researchers concur-

rently tested a vaccine called “rVSV-ZEBOV” in a total of

158 healthy adults. “The preliminary results on tolerabi-

lity and safety, as well as the immune response, are pro-

mising,” explains DZIF researcher Prof Marylyn Addo,

who is leading the trial at the UKE. “The data from this

trial are very helpful for further clinical trials, for examp-

le on people who have been in contact with Ebola in Gui-

nea, and they have also helped determine the dosage.”

Other projects in the research field include epidemio-

logical studies on origin, transmission and spread of

the MERS coronavirus. The virus, which up to now has

been predominantly transmitted to humans from ca-

mels, leads to severe respiratory illness, the so-called

Middle East Respiratory Syndrome (MERS). Virologists

fear that the virus may alter and subsequently transmit

more easily from humans to

humans—which could result

in larger epidemics. For this

reason, DZIF researchers

are working intensively on

further investigating and

introducing a vaccine. Prof Dr Marylyn Addo,HeadofInfectiologySection,Departmentof

InternalMedicineI,attheUniversityMedicalCenterHamburg-Eppendorf

“The Ebola trial was a networking success. We would not have made it without the other colleagues, the DZIF and

international networking.”

88 Tuberculosis

Modern approaches to f ighting an ancient epidemic

Tuberculosis (TB) has become rare in Germany.

However, it is a major global public health problem:

nine million people contract TB every year; 1.5 mil-

lion die from the disease. The TB pathogen, the so-

called tubercle bacillus, typically infects the lungs

and spreads to other organs. DZIF scientists in the

research field “Tuberculosis” investigate new me-

thods for prevention and diagnosis. Furthermore,

they participate in developing and testing new

active substances against TB.

At the partner sites Hamburg-Lübeck-Borstel,

Hannover-Braunschweig, Munich and Tübingen, DZIF

scientists link basic research with clinical applications

in Germany. Beyond this, together with 600 colleagues

from the European research

network TBNET, they are

challenged with a global

problem: there is no effec-

tive vaccine against tuber-

culosis. Treatment consists

of several antibiotics and often takes many months. Side

effects, high treatment costs and a lack of compliance

often lead to abandonment of treatment. Co-infections

and antibiotic-resistant tubercle bacilli complicate

the situation. Researchers are particularly concerned

about the rapid increase of multidrug-resistant and

extensively drug-resistant TB strains (M/XDR tuber-

culosis), for which patients seldomly receive effective

treatment.

Tracing and tracking multidrug-resistant pathogens

around the world

Multidrug-resistant TB strains are spreading, espe-

cially in Eastern Europe, Africa and Asia. DZIF scien-

tists are doing genuine detective work to stop their

spread and to trace the evolutionary history of tu-

bercle bacilli. In a consortium consisting of 55 TB re-

searchers, they analysed genetic fingerprints of almost

5,000 tuberculosis strains of the so-called Beijing

lineage, from 99 countries. With this study, they could,

for the first time, show the global spread of multidrug-

resistant (MDR) clones of this particular strain. The

Beijing strains originated over six thousand years ago.

The strains probably spread from Eastern China to

Europe via the Silk Road, and by ship. Towards the end of

the 19th century, they spread into Russian Republics

and into the Pacific region during surges of migration.

Soldiers, refugees and famine during the First World

War accelerated the spread. One remarkable finding

was that current high rates of MDR TB in Eastern

Europe are mainly due to two main outbreak strains.

Beneficial genetic mutations in the bacteria are most

likely the reason for their efficient transmission and

extreme spread over the last 20 years. “Amongst

other things, this study also highlights the impor-

tance of efficient tuberculosis surveillance and rapid

identification of antibiotic

resistance with molecular

methods,” explains Prof

Stefan Niemann, Head of

the study at the Research

Center Borstel. “Out-

breaks and spread of multidrug-resistant tuberculosis

could then be identified and contained in time.”

Reliable diagnostics and tailored

therapy required

Countries with high TB rates often do not have the re-

sources to treat their patients. “It is our human duty to

take care of the patients in these countries,” says Prof

Christoph Lange, Head of Clinical Infectious Diseases

in Borstel. In a TBNET trial, DZIF researchers concen-

trated on TB infected patients who had weak immune

systems due to pre-existing illnesses. These patients

run a high risk of developing tuberculosis disease. Here,

the researchers tested the reliability of TB tests: they

compared two, WHO-recommended rapid molecular

diagnostic tests to the conventional tuberculin test.

Especially patients with HIV infections developed TB

symptoms whereby the rapid molecular tests did not

confirm all cases. Patients with weak immune systems

who received preventive antibiotic treatment during

the study did not develop symptoms. “This result shows

Prof Dr Christoph Lange,HeadofClinicalInfectiousDiseases

“The DZIF bridges the gap between research and patient care.”

that we have to redefine risk groups and use preventive

therapy to contain the spread,” says Lange. Overall, the

DZIF scientists are therefore increasingly focussing on

concepts of tailoring treatment to adjust it to antimicro-

bial resistance and pre-existing illness.

Beyond this, the DZIF is also active in endemic areas.

For example, it is funding the establishment of a new

trial centre in Bucharest, Romania. Here, new drugs

are to be tested in the largest EU tuberculosis hospi-

tal. Additionally, a consultation service for doctors has

been established, where DZIF infectious diseases spe-

cialists are available around the clock to give competent

advice. In a national online teleconference, the doctors

and scientists discuss best case management of MDR-

TB patients with competent colleagues from other sites

in Germany. In a national TB cohort, DZIF researchers

are investigating biomarkers for individualising therapy.

Not without a face mask: tuberculosis bacteria are transmitted by coughing and sneezing.

10 Malaria

Fighting against intermittent fever

Every year, there are approximately 200 million cases

of malaria and 600,000 malaria deaths; 90 percent of

which occur in Africa. Children under five years are

particularly vulnerable, where the infection is one of

the major causes of death.

Parasites, so-called plas-

modia, cause this tropical

disease which is transmit-

ted through mosquitos.

Typically, the disease pre-

sents with intermittent

phases of fever. DZIF re-

searchers in Tübingen, Heidelberg and Hamburg fo-

cus on developing new methods of prevention and

therapy, as well as epidemiological measures to fight

the spread of malaria.

Despite extensive research, the fight against malaria

has been challenging scientists all over the world: re-

gional genetic differences in the pathogen and in

populations complicate treatment. Further obstacles

are co-infections with other

pathogens and resistance

to conventional treatment.

Consequently, researchers

have to constantly ad-

just their interventions to

fight this highly adaptable

pathogen. The DZIF sci-

entists are therefore also looking for alternative path-

ways. The main areas of focus in the research field

“Malaria” are to test and optimise alternative methods

of vaccination, and to develop parasite inhibitors.

Furthermore, scientists are investigating the regional

The DZIF is working closely with African partner institutions to fight malaria.

“The DZIF’s collaborations and support have made it possible to bridge the gap between

basic research and clinical research.”

spread of the pathogens, in order to effectively plan

malaria interventions in the affected areas. To this

effect, the DZIF is working together closely with African

partner institutions in Ghana, Burkina Faso and Gabon.

Protection against dangerous parasites

Although the quest for a vaccine has been ongoing for

years, only a moderately effective vaccine, at best, will be

available in the near future. At the Institute for Tropical

Medicine of the University of Tübingen, DZIF researchers

are testing a new vaccination method in a clinical trial.

They intravenously inject live plasmodia and simulta-

neously administer a drug for malaria to weaken them.

This method has been shown to fundamentally work in

animal models, as well as in a clinical trial that used infec-

ted mosquitoes instead of the purified plasmodia. It re-

sults in effective vaccine protection. “By using the entire

pathogen, we obtain a strong and broad immune re-

sponse,” says Dr Benjamin Mordmüller at the DZIF part-

ner site Tübingen. “This vaccination method stands good

chances of being approved,” Mordmüller believes. “Then

it can also be used to prevent malaria in children in Africa.”

Fever does not necessarily mean malaria

Especially children are in urgent need of protection against

malaria. In African countries, they frequently suffer from

fever of unclear origin. “Differentiating between malaria

and other infections is hardly possible, given the available

facilities,” explains Prof Jürgen May, Head of the Research

Group on Infectious Disease Epidemiology at the Bern-

hard Nocht Institute for Tropical Diseases in Hamburg. In

one trial conducted at the African partner institutions, the

DZIF team led by May investigated children with severe

febrile illnesses in hospitals. With the help of conventio-

nal methods and molecular diagnostics, they determined

the frequency, risk and treatment options of malaria co-

infections. In doing so, they could confirm that the de-

gree of severity of the illness was higher in cases of co-

infection. Conversely, malaria also facilitates simulta-

neous infection with other pathogens, particularly salmo-

nella, as the team from Hamburg observed. “We therefore

want to develop a rapid bedside test,” May explains.

Further projects

In other projects, DZIF researchers are developing novel

parasite inhibitors. Moreover, scientists in Hamburg are

developing mathematical models to describe the regional

spread of the parasites. Models can also help determine

the parasites’ life cycles in infected people’s blood.

12 HIV

Luring retroviruses out of hiding

Since its discovery in the year 1983, the human im-

munodeficiency virus (HIV) has spread worldwide: 35

million people are HIV positive, 1.5 million die every

year from the consequences of HIV infection—the

immune deficiency syndrome AIDS. As yet, there has

been no effective vaccine and no prospect of cure. In

view of this situation, the DZIF research field “HIV”

has set itself the ambitious goal of developing new

treatment methods, with the particular aim of curing

the disease.

HIV belongs to the family of retroviruses: they insert

their genetic information into the host’s genome befo-

re becoming active. Of all cells, HIV chooses human im-

mune system cells as its host. Once integrated into the host

genome of these immune cells, the virus’s genes become

insusceptible to attack—by both the human immune

defence system and by drugs, as these only target the free

viruses in the blood. As soon as treatment is omitted, the

virus’s genetic material is reactivated, and the body gets

flooded with viruses once again. Virologists describe this

hide-and-seek game as latency, and consider this to be the

reason why HIV has so far remained incurable.

Discovered in its hiding place

In Heidelberg, DZIF scientist Dr Marina Lusic investigates

HIV latency, in collaboration with colleagues from Cologne

and Hamburg. The virologist is convinced, “Only by under-

standing the mechanisms of HIV latency will we be able

to develop therapeutic countermeasures.” In 2014, the

young scientist received a tenure-track position funded

by the DZIF, for preclinical HIV research at the University

of Heidelberg. This exemplifies that furthering careers

at the DZIF also plays an important role. The scientist

investigated how the virus alters the nucleus and genome

structure of infected cells to suit its purpose. Together

with her team in the Department of Infectious Diseases

at the Heidelberg University

Hospital, Lusic discovered

that the viruses frequently

insert their genetic material

into specific regions of the

cell nucleus. Especially often,

the viral genome is found

directly behind the nuclear

pores—the entry channels to the nucleus. “Imagine you are

a visitor to an event and you are late. You will come through

the door and take the first available seat,” Lusic explains.

A new approach to treatment and prophylaxis

Antiviral drugs keep HIV under control and delay the on-

set of AIDS (Acquired Immune Deficiency Syndrome).

However, they have to be taken over a lifetime and fre-

quently have side-effects. They are often too expensive

for patients living in developing countries. Additionally,

the virus easily develops resistance. “We therefore need

new therapies,” explains Prof Gerd Fätkenheuer, Head of

the Division of Infectious Diseases at the University Hos-

pital of Cologne. “Currently, intensive research is ongoing

which investigates how the pathogen can be lured from its

hiding place and activated with drugs to subsequently be

destroyed in the blood.” Together with researchers from

the Rockefeller University in New York (USA), DZIF physi-

cians from the University Hospital of Cologne are investi-

gating a new treatment approach. The international team

has tested a new generation of antibodies in humans for

the first time. The trial, also funded by the DZIF, showed:

the antibodies can effectively neutralise a large number

of different HIV viruses and significantly reduce infected

people’s viral loads. “The antibody´s effect proved to be

comparable to the current drugs being used for treat-

ment,” says Fätkenheuer. “This method opens up a new

field of HIV treatment and could, in future, possibly also

be used as a preventive measure after fresh infections. Its

principle is similar to that of a passive vaccination.”

A further DZIF team, led by Prof Joachim Hauber at the

Heinrich-Pette Institute in Hamburg builds on a gene ther-

apy approach: developing new specific enzymes that are

inserted into the host cells,

which can detect the viral

genome in the nucleus and

specifically excise it from the

human DNA. Subsequently,

this should prevent a later

activation of the “dormant”

virus. Other projects inves-

tigate early HIV infection and their long-term effects,

also focussing on patients in Africa in addition to those in

Germany.

Real hope for cure

A hepatitis C virus finds its way into a liver cell using different adhesion and receptor molecules.

The inflammatory liver disease (hepatitis), caused

by infections with hepatitis virus types A to E, is glo-

bally widespread. More than half a billion people suf-

fer from chronic hepatitis B, C and/or D infections

worldwide. In the DZIF research field “Hepatitis”,

researchers develop and test new antiviral drugs.

They investigate their mechanisms of action and their

effective combinations. Additionally, they conduct

epidemiological studies to improve patient access to

treatment.

infections often have complications and chronic courses

of disease. They have a high risk of developing secondary

diseases such as liver cirrhosis and liver cancer. A vaccine

against the hepatitis B virus (HBV) exists, which simulta-

neously prevents hepatitis D virus (HDV) infection. Anti-

viral drugs for HBV are also available; they curb viral rep-

lication but do not actually cure the disease. There is no

vaccine available against hepatitis C (HCV). Up to now,

the usual treatment of chronic hepatitis C infection has

consisted of a combination of three drugs, one of which

has to be injected regularly.

A cure for hepatitis C

New active agents have changed the treatment of

chronic hepatitis C tremendously. “Hepatitis C is the first

chronic viral infection that has become curable. This is

an enormous success story. It will change medicine,” says

DZIF Professor Michael Manns, Director of the Depart-

ment of Gastroenterology, Hepatology and Endocrinolo-

gy at the Hannover Medical School (MHH). “Treatment

now only consists of a combination of several tablets,

can be significantly shortened, causes less side effects

and resistance, and is also effective against difficult-to-

treat forms of hepatitis C,” explains Prof Manns. The new

drugs, for example, inhibit the enzymes RNA polyme-

rase and protease, which the virus needs for both rep-

lication and maturation, thereby suppressing both. The

mechanism of action of the

new substance “daclatas-

vir” was unknown for a long

time. DZIF Professor Ralf

Bartenschlager, virologist at

the University of Heidelberg,

has now deciphered its

mode of action: it binds to

the viral protein NS5A. The

virus needs this protein both for replicating its RNA and

assembling new virus particles. However, therapy with

the new active substances is very expensive.

Hepatitis D: Improving investigations

and cure rate

HDV infection only occurs as a co-infection with hepatitis

B, and causes the most aggressive form of viral inflam-

mation of the liver. Conventional therapy with inter-

feron alpha has considerable side-effects and only cures

less than twenty percent of treated patients. Therefore,

there is an urgent need for new trials to investigate new

treatment approaches. The required number of patients

for such trials can only be achieved through international

multicentre trials. A DZIF project at the MHH (HepNet

Study-House of the German Liver Foundation) therefore

established a global registry for patients suffering from

chronic HBV/HDV infection. “The hepatitis D registry is

to enable scientists to investigate the disease,” explains

project coordinator Dr Svenja Hardtke. Patients can better

access information about their condition to obtain the op-

timal treatment. Furthermore, it enables the participating

centres to get a rapid overview of their patients’ symp-

toms and therapies. Patients undergo regular follow-up

examinations in which their symptoms, liver and kidney

function, hepatitis serology

and other blood values are

ascertained. Dr Hardtke is

happy, “In November 2014,

we registered far over 600

patients and twelve partici-

pating centres worldwide.

The virus blocker “Myrcludex

B”, developed at the DZIF

partner site Heidelberg, has successfully completed the

first clinical trial phase and is considered to be an effective

candidate for treating, and possibly even curing, hepatitis

B and D. Furthermore, researchers at the DZIF partner

site Hannover-Braunschweig are looking for biomarkers

that give an indication of the course of disease and effi-

cacy of treatment, which subsequently enables individu-

alised treatment.

Gastrointestinal Infections

Targeted treatment instead of broad spectrum antibiotics

Gastrointestinal infections are globally widespread and

are not only unpleasant, but also underestimated: ac-

cording to the WHO, about 1.5 million people die each

year from diarrhoeal disease caused by pathogens like

Salmonella, E. coli and rotaviruses. DZIF scientists in the re-

search field “Gastrointestinal Infections” develop active

substances and vaccines directed at specific pathogens.

Moreover, they investigate measures for diagnosing and

maintaining the natural gut flora which helps to protect

against infections and chronic diseases.

Conventional antibiotic therapy often damages both the

pathogens and the natural gut flora to the same degree.

Using antibiotics can cause a shift in composition of the

gut flora which may facilitate the development of chronic

diseases such as asthma and diabetes. Additionally, anti-

biotic resistance may develop, consequently leading to in-

fections with difficult-to-treat bacteria. Newer treatment

approaches are therefore not directed at the pathogens

themselves, but against the characteristics of bacteria

that cause illness, so-called virulence factors.

Inhibiting instead of damaging

DZIF researchers at the partner sites Tübingen and

Hannover-Braunschweig, as well as at the University

of Münster, are following the approach of inhibiting

bacteria’s pathogenic characteristics instead of damaging

the actual pathogens themselves. Active agents working

on this principle are called pathoblockers. “They basically

prevent the pathogen from penetrating the gut wall, or in-

hibit their toxins in the gut,” explains Prof Ingo Autenrieth,

Medical Director of the Institute of Medical Microbiology

and Hygiene at the University Hospital Tübingen. On a

research platform together with DZIF colleagues, Au-

tenrieth and his team are systematically searching com-

pound libraries for such substances. A potential target

structure for future antiinfectives could be a type III

secretion system, commonly found in bacteria which, for

example, salmonella use like

a needle to inject toxins into

host cells. On their quest for

substances that inhibit this

mechanism, the researchers

tested around 5,000 active

substances, and were suc-

cessful: “We have found a

handful of effective substances which could be potential

candidates,” Autenrieth says happily.

Helicobacter pylori: vaccine instead of antibiotics

Helicobacterpylori is also an important gut pathogen. The

bacteria cause gastric infection in half of the world’s pop-

ulation. It is the main cause of gastric ulcers and gastric

cancer. About ten percent of the world’s population de-

velop a gastric ulcer once in their lifetime; 750,000 peo-

ple worldwide die of malignant gastric cancer every year.

Antibiotics that are effective against Helicobacter pylori

exist and therefore also protect against the secondary

complications of infection. However, “Many patients have

become untreatable due to antibiotic resistance, and the

rates of resistance are increasing steadily,” adds Prof

Markus Gerhard from the Technische Universität München

(TUM). For this reason, the TUM scientists, in collaboration

with DZIF scientists in Hannover, are developing a thera-

peutic vaccine: “We want to vaccinate adults infected with

Helicobacterpylori who have not yet developed gastric ul-

cers or gastric cancer, so as to protect them from deve-

loping these conditions,” Gerhard explains. “In 2014, vac-

cine production was initiated in a spin-off company and

preclinical tests were completed successfully. First clinical

studies are pending.”

Microbiome research

A further focus of the research field is microbiome research.

In January 2014, DZIF scientists at the partner sites Han-

nover, Munich and Tübingen founded the Center for Gas-

trointestinal Microbiome Research (CEGIMIR) under the

umbrella of the DZIF. This new research platform will more

intensively investigate the microbial diversity of the gastro-

intestinal tract and its role in infections. The alliance aims to

discover diagnostic biomar-

kers that give an indication of

individual sensitivities to spe-

cific gut pathogens. Based on

these, therapies will be de-

veloped that protect the gut

flora and/or fortify the im-

mune system. “For medicine,

enormous potential lies in gaining a better understanding

of the microbiome’s role in health and disease, and the di-

verse interactions between gut pathogens and gut flora. The

DZIF has made it possible for us to pool our research ca-

pacities in this field and to move forward together quickly,”

says Prof Sebastian Suerbaum, Director of the Institute of

Medical Microbiology and Hospital Epidemiology at the

Hannover Medical School, and Coordinator of the DZIF re-

search field “Gastrointestinal Infections”.

MedicalMicrobiologyandHygieneattheUniversityHospitalTübingen

Infections of the immunocompromised Host

Decoding the immune system’s mechanisms

Pathogens, harmless to healthy people, can become

a life-threatening danger to people with impaired im-

mune systems. These include transplant and cancer

patients, chronically ill people, people with inherited

or acquired immune deficiencies, and elderly patients.

These people are difficult to treat with conventional

antibiotics. The DZIF research field “Infections of the

immunocompromised Host” therefore focuses on in-

vestigating immune defects, identifying biomarkers for

infection control, as well as developing new approa-

ches to prevention and immunotherapy.

The prevention and treatment of infections in immuno-

compromised patients is playing an ever growing role—

especially in the day-to-day life of hospitals. Better

knowledge of the causes and mechanisms of immune

deficiencies form a basis for developing new therapies.

More knowledge about immune deficiencies

“We learn a lot from patients with rare, inherited

diseases of the immune system,” emphasizes DZIF Prof

Christoph Klein, Director of LMU Munich’s Dr. von

Hauner Children‘s Hospital. In order to understand these

immune defects, Klein and his team look for the gene

loci and gene products of impaired functions. In doing

so, they have found a defective gene which codes for

“Jagunal 1” (JAGN1), an important transport protein. It

regulates the function of neutrophil granulocytes, cells

of the immune system important for the defence against

fungal infections. The researchers investigated JAGN1

gene defects in mice, and discovered that administe-

ring them with a certain granulocyte stimulating factor

had a protective effect against infections with Candida

albicans, a type of yeast which is responsible for many

fungal infections in humans. Clinical trials now need to

be conducted to investigate whether this is a treatment

option transferable to humans. “Each defect we identify

is like part of a puzzle. The more of these we find, the bet-

ter we can understand the immune system’s mechanisms

and can also treat other patients,” Klein stresses.

More immunotherapy for cancer patients

DZIF scientist Prof Uta Behrends, from the university

hospital of the Technische Universität München, found

a piece of the puzzle which helps understand the con-

nections between infections,

the immune system and can-

cer. It involves the Epstein-

Barr virus (EBV). Most people

in Europe contract this virus,

but the infection goes un-

noticed in most cases. The

pathogen remains “hidden”

in infected cells over many

years. It often only becomes noticeable when the in-

fected person develops a weak immune system, as

happens with blood stem cell and organ transplants.

These patients then suffer more frequently from cancer

of the white blood cells, so–called lymphomas. EBV

is an important stimulus for developing lymphoma in

patients who have had a transplant. To treat these

patients, the same defence mechanism that protects

EBV-infected people with healthy immune systems

can be used: their infection is controlled by T

lymphocytes, in short T cells, that specifically target EBV.

In the same manner, immunocompromised lym-

phoma patients can be cured with infusions of EBV-specific

T cells. In order to develop these treatment approaches

further, Behrends and her team investigated the effect of

different EBV-specific T cells in mouse models. The result

was surprising: “Lymphoma growth was inhibited by some

T cells, promoted by some and unaffected by others,”

says Behrends. Treatment

with solely tumour inhibiting

EBV-specific T cells could

therefore further improve

efficacy of current immuno-

therapy approaches.

Another important project

in the research field is to

continuously develop the Transplant Cohort. Here,

transplant patients are examined before and after proce-

dures, medical data and samples are collected and ana-

lysed. In doing so, researchers want to find out why some

patients are more susceptible to infection than others.

Coordinator:

Prof Dr Dirk BuschMünchen

The Epstein-Barr virus can “hide” in infected cells over many years.

“Physicians and scientists from the most varied disciplines come together at the

interfaces of DZIF projects – in this lies the greatest potential for innovation.”

The emergence of resistance is monitored in hospitals, as is antibiotic use.

Healthcare-associated and Antibiotic-resistant bacterial Infections

Getting hospital pathogens under control

Hospital pathogens are one of the biggest challenges in

healthcare. According to the German Society for Hospital

Hygiene, approximately 900,000 hospital-acquired

infections occur in Germany every year. The threat of

falling back into a “pre-antibiotic era” is growing, espe-

cially because of the increase in antibiotic-resistant pa-

thogens. In order to better control the pathogens, DZIF

scientists in the research field “Healthcare-associated

and Antibiotic-resistant bacterial Infections” are con-

centrating on several issues simultaneously: they are

encouraging a more targeted use of antibiotics, looking

for new active substances, and developing improved

hospital hygiene management.

In particular, intensive care units run a high risk of de-

veloping and spreading multidrug-resistant pathogens.

Especially the inappropriate use of broad spectrum anti-

biotics is promoting an increase in resistance. This results in

longer and more severe courses of disease, along with

higher treatment costs. Methicillin-resistant Staphylococcus

aureus (MRSA) strains and multidrug-resistant gram-

negative Enterobacteriaceae are especially dreaded in

hospitals. Some pathogens have even become insensi-

tive to the “last resort” antibiotics that are reserved for

emergencies only.

Mobile resistances identified and stopped

At the University Hospital of Gießen, Dr Can Imirzalioglu

and his team also encountered this problem. During a

routine examination in a hospital in Hessen, they iden-

tified various bacteria that produced carbapenemase.

This enzyme renders carbapenem, a “last resort” anti-

biotic, ineffective. “As very different bacteria produce

this enzyme, we suspected that its genetic information

may not be located on a bacterial chromosome, but on

a plasmid,” says Imirzalioglu. These plasmids, or mobile

Page 23: German Center for Infection Research - DZIF · German Center for Infection Research (DZIF) try to answer these questions, and others. They develop new drugs, vaccines, and preventive

21

genetic elements, consist of short ring-shaped DNA

and can easily transfer resistance between bacteria.

And indeed, in each sample, the DZIF bioinformatici-

ans in Gießen localised a

resistance-gene encoded in

a plasmid. For the first time

in the world, they success-

fully identified and charac-

terised the mobile genetic

element as responsible for

transferring the carbape-

nem resistance while the outbreak was still ongoing. In

doing so, they could rapidly identify the source of infec-

tion and the routes of spread, and therefore contain the

outbreak.

Antibiotic stewardship: reducing resistance in the

long-term

Together with other scientists, Prof Winfried Kern, Head

of the Division of Infectious Diseases at the University

Medical Center Freiburg, developed guidelines for anti-

biotic use in hospitals, as a prevention measure against

hospital pathogens. “Treatment has become so com-

plicated that a surgeon will almost be unable to select

a correct antibiotic without consulting an infectious di-

seases specialist,” is how the DZIF researcher describes

the situation. In the national guidelines, issued in 2014,

experts recommend using “antibiotic stewardship” pro-

grams, ABS for short. Here, a multidisciplinary team

advises hospital colleagues on selection, dose and admi-

nistration of an optimal antibiotic. It recommends speci-

fic antibiotics for certain diseases and excludes others.

ABS experts also compile lists of recommended drugs

for hospitals, and monitor antibiotic usage, as well as the

emergence of resistance. First results, including those

from DZIF studies, show: 10-40 percent of the adminis-

tered drugs can be omitted, the duration of treatment

can be shortened, and resistance can be reduced in the

long-term.

In collaboration with an international team, Prof Evelina

Tacconelli, Head of the Division of Infectious Diseases

at the University Hospital Tübingen also developed

European guidelines for controlling multidrug-resistant

gram-negative bacteria. In view of the increasing spread

of pathogens across all borders, the DZIF researcher

underlines the importance

of Europe-wide recom-

mendations. “This is parti-

cularly important for coun-

tries which do not have

national guidelines of their

own,” Tacconelli thinks. She

brings expertise in infection

research, which she gained in other European countries,

to the DZIF. Further projects in this research field focus

on developing new substances that inhibit colonisation

of multidrug-resistant Staphylococcus, as well as mea-

sures against multidrug-resistant Enterobacteriaceae in

cancer patients.

Novel Antiinfectives

Finding valuable natural treasures

Medicine without antibiotics is no longer imaginable.

They are the most important agents against infectious

diseases. However, more and more pathogens are

developing resistance, making the former “silver

bullets” less and less effective. Although there is a

great need for antibiotics, the pharmaceutical industry

has hardly introduced any new ones to market – they

are not lucrative enough. The research field “Novel

Antiinfectives” is counteracting this development:

it identifies new target structures for antibiotics,

develops candidate agents and strategies for fortifying

the body’s immune defence.

Fungi and bacteria produce active substances to protect

themselves against other microorganisms, amongst

which new antibiotics could potentially be found.

Scientists comb through natural substances in marine

sediments, soil and animal excrements in pursuit of such

organisms. DZIF researchers see a particularly high

potential in soil bacteria. However, less than one percent

of all bacteria and fungi are cultivatable in conventional

culture media. The quest for antibiotics is painstaking

and has a low rate of success.

Valuable resource against gram-positive bacteria

Together with DZIF members, an international team of

researchers from the USA, took the trouble of searching

and was rewarded: thanks to a special culturing method,

the scientists were able to isolate previously uncultu-

red ground bacteria, and subsequently discovered an

untapped source of new antibiotics. By means of a new

screening method, they discovered “teixobactin”. Prof

Tanja Schneider, leader of a DZIF junior research group

at the University of Bonn, is happy, “It is a highly interest-

ing active substance and the first member of a new class

of antibiotics.” The biologist and her team deciphered its

mechanism of action: “Teixobactin simultaneously tar-

gets many different important sites in bacterial cell wall

synthesis, and makes it almost impossible for bacteria

to use their adaptation strategies,” Schneider empha-

sises. In first tests in mice,

the substance was effective

against numerous proble-

matic gram-positive bacteria

and did not cause resistance.

The scientists consider it to

be a promising new drug

candidate against bacteria such as Staphylococcusaureus

and Mycobacteriumtuberculosis.

Beacon of hope in the fight against

hospital pathogens

Gram-negative bacteria are even more challenging: “They

have two cell membranes. Potential agents have to

penetrate through both to be effective,” explains

Prof Rolf Müller, Director of the Helmholtz Institute for

Pharmaceutical Research Saarland (HIPS). Despite

complex requirements, Müller and his colleagues from

Saarbrücken succeeded in isolating an active substance

from myxobacteria at the Helmholtz Centre for Infec-

tion Research (HZI) in Braunschweig. Müller is happy,

“We have discovered a completely new substance class,

and have christened it ‘cystobactamides’.” In tests, they

have been effective against the gram-negative bacteria

Escherichia coliand Acinetobacter baumannii. The active

substance works by preventing bacterial DNA from

being compacted like a twisted garden hose. Interfering

with this process, results in the bacteria’s metabolism

becoming impaired. By chemically modifying the active

substance, the researchers hope to enhance this effect

and broaden the spectrum of targetable bacteria. “If we

succeed in doing this,” says Müller, “cystobactamides will

be a real beacon of hope in the fight against hospital

pathogens.”

Furthermore, the DZIF scientists analyse microbial ge-

nomes at the partner site Tübingen. With new tech-

niques, such as genome mining, they looked for “silent”

gene segments which could code for potential active

substance syntheses. After activating these gene clus-

ters, the scientists discovered promising active substan-

ces in the glycopeptide class. In 2014 alone, the DZIF

research field “Novel Anti-

infectives” discovered a to-

tal of three new classes of

antibiotics. The chemists now

need to work at optimising

the candidate active subs-

tances, for good tolerability,

effectiveness against a broad spectrum of pathogens

and to prevent the development of resistance as far as

possible.

Product Development Unit

Well-supported, from the target molecule to approval

The journey from discovering a new target molecule in

the body to the approval of a suitable drug takes years.

95 percent of all active agent candidates fail before

the clinical trial stage. Developing a new drug requires

knowledge of the regulatory requirements, production

and patents. Here, the DZIF’s “Product Development

Unit” advises and supports its colleagues.

The DZIF infrastructure consists of two offices. The

Translational Project Management Office (TPMO) at the

Helmholtz Centre for Infection Research in Braunschweig

develops plans for drug development, assists with their

implementation, and advises on commercial matters. The

Office for Scientific and Regulatory Advice (OSRA) at the

Paul-Ehrlich-Institut in Langen advises on the approval of

clinical trials, therapeutic agents and vaccines. OSRA also

analyses typical obstacles in drug development and ways

of avoiding them.

From idea to product

“We are like pilots guiding the way through the thicket

of regulations and product development,” is how Dr

Christoph Conrad from the Paul-Ehrlich-Institut describes

OSRA and TPMO’s responsibilities. He, along with his

colleagues, join the DZIF research fields’ work meetings

Coordinator:

Prof Dr Klaus CichutekLangen

to identify promising approaches for potential products

and assess the prospects of their further development.

Conrad emphasizes the benefit of contacting the office

early on: “Researchers are welcome to get in touch from

the moment they have a good idea for a potential pro-

duct.” This is how the utilisation of scientific insights and

the subsequent realisation of medicinal products can be

improved. Once the pilots are on board, they provide ad-

vice and support for developing trial designs, planning and

managing product development, for questions about clini-

cal testing as well as for marketing approval.

From the Ebola emergency to a successful vaccine

The DZIF activities during the Ebola outbreak in 2014

exemplify how the infrastructure successfully manages

complex and critical translational projects. With the help

of the “Product Development Unit”, important stakehol-

ders were brought together to promptly initiate a clinical

phase I trial for the candidate vaccine “rVSV-ZEBOV” in

Germany. The DZIF infrastructure played a decisive role

in this as a point of contact with the WHO, the Canadi-

an health authority Health Canada, which developed the

vaccine, the licensee NewLink, sponsors, the trial centre

and the applicants as well as the authorities concerned.

This enabled the development of a promising candidate

vaccine within a few months, which was subsequently

available for further trials.

With the help of the “Product Development Unit” at the DZIF, a phase I trial for an Ebola vaccine candidate was initiated.

Clinical Trial Unit

Human trials for humans

Coordinator:

Prof Dr Oliver CornelyKöln

New drugs have to be tested thoroughly in clinical trials

before they can be brought onto the market. The DZIF

“Clinical Trial Unit” (CTU) consists of clinical trial units

specialised in infectious diseases. Here, active sub-

stances are medically tested under the highest quality

standards.

These clinical trials test tolerability, efficacy and dosages

of drugs and vaccines. In Germany, strict regulations and

standardised operating procedures must be adhered to.

Research on humans demands competency, precision and

utmost attention. In order to ensure reliable results, clini-

cal trials have to be planned thoroughly in advance, con-

ducted in a controlled environment, tested systematically

and evaluated carefully.

DZIF quality objectives are external signs of quality

Currently, eleven clinical trial units are working together

within the DZIF infrastructure. The “Coordinating Office”

in Cologne has longstanding experience with which it co-

ordinates the alliance, manages feasibility requests and

the central management system. In 2014, its main focus

was to implement a comprehensive strategy for conduc-

ting clinical trials in all participating DZIF clinical trial units.

“We have established a joint quality management system,”

explains Prof Oliver Cornely, Coordinator of the DZIF infra-

structure. This system is based on so-called Standard

Operating Procedures (SOPs), as has been recommen-

ded by the Federal Ministry of Education and Research

(BMBF).

Good internal collaboration paves the way

to external collaboration

The networking infrastructure between the partner sites,

consistently high quality standards, efficient operating

procedures, and experience in collaborating between

academic partners and companies make the units suitable

for clinically testing active substances, and this is true not

only for substances developed within the DZIF. “A net-

work that maintains quality standards like these is highly

valuable to the industry,” explains Angela Steinbach, the

CTU project manager. One major advantage of the CTU

is that one central contact person enables access to many

trial units. Furthermore, this expertise strengthens the

DZIF’s position as a partner in international infectious di-

sease networks.

Consistently high quality standards are implemented across the DZIF’s clinical trial units.

African Partner Institutions

Reliable alliances in areas of risk

Coordinator:

Prof Dr Jürgen MayHamburg

Like many other infectious diseases, AIDS, tuberculosis

and malaria occur rarely in Germany. They are, how-

ever, widespread in many parts of Africa. In order to

better investigate these diseases, the DZIF institutes

foster partnerships with research establishments on

the African continent.

The DZIF promotes collaborations between its partner

sites and renowned research establishments in Ghana,

Gabon, Burkina Faso and Tanzania. “The DZIF institutions

have been working together with these partners for over

a decade,” says Prof Jürgen May, Coordinator of the infra-

structure “African Partner Institutions”. Thanks to long-

standing relationships, contacts and agreements in these

reliable alliances have existed for years. They offer DZIF

researchers excellent administrative and logistic con-

ditions on the ground: from the provision of accommo-

dation and modern laboratories to infrastructures for

clinical trials all the way through to facilitated import and

export arrangements for research projects. The Ebola

virus vaccine efficacy trial conducted in Gabon, once again

demonstrated the potential in these partnerships.

Tracking pathogens locally

Together with their African colleagues, DZIF researchers

conduct epidemiological surveys to better understand

the temporal and spatial distribution of pathogens in the

affected areas. In one trial, conducted at all four partner

institutions, the teams collected samples from children

with severe febrile illnesses. The samples were initially

analysed on-site with rapid tests and microbiological in-

vestigations, and later in Germany with special molecular

diagnostic tests. Besides malaria parasites, other patho-

gens were often found to be the cause of life-threatening

febrile illness in children.

Improving on-site diagnostics

“We therefore want to improve bedside testing,” says

May, “and aim to find simple methods, particularly for re-

gions with limited access to health care.” Together with

the Fraunhofer Institute for Silicon Technology, DZIF re-

searchers are developing a new diagnostic testing kit

which rapidly analyses blood samples using microchips.

The chips will analyse a choice of eight biomarkers in a

convenient device with a modular design. The biomarkers

can be selected according to the needs in the respective

areas.

Trial participants were also recruited from the Agogo Presbyterian Hospital in Ghana.

Natural Compound Library

Collected works of nature

Microorganisms not only cause infections, they also

produce substances that can fight other pathogens.

Most antibiotics have been developed from such natural

substances. However, up to now, only a few substances

have been investigated for their medicinal effects. In

the “Natural Compound Library”, the DZIF has collected

compounds from bacteria, fungi and plants. They are

available for research to all DZIF establishments.

DZIF researchers can draw on collections from the

Helmholtz Centre for Infection Research (HZI), the

Helmholtz Institute for Pharmaceutical Research

Saarland (HIPS), the Hans Knöll Institute in Jena as well as

the University of Tübingen. These establishments isolate

and characterise microorganisms and fungi that produce

potential active substances, and subsequently analyse

them with methods from system biology, biotechnology

and functional genomics.

New experts from research and industry

Prof Ulrich Nübel brings his expertise in gene function

research to the DZIF. He has been Professor of “Microbial

Genome Research” at the German Collection of Micro-

organisms and Cell Cultures (DSMZ) since June 2014.

From gene sequences of bacterial strains, Nübel can read

the course of infectious disease outbreaks or the spread

of resistance, and can identify the potential in new active

substances. Prof Mark Brönstrup, who heads the Depart-

ment of “Chemical Biology” at the HZI, paves the way to

new drugs. Under a DZIF professorship, he is looking for

new testing systems and contributing to developing and

optimising active substances. In doing so, he draws on his

experience from the pharmaceutical industry.

Ordering substances from the library

In the long term, an extensive chemical substance library is

to be established and made available to the DZIF research

fields for screenings. “We have resources for both functio-

nal genomics and fermentation, as well as for developing

active substance screenings,” emphasises Prof Rolf Müller,

Coordinator of the infrastructure “Natural Compound

Library”. “In this way, at the request of DZIF colleagues, we

can identify substances, reproduce them in a milligram to

gram range and send them in minimal amounts on micro-

array plates along with thousands of other substances.”

This testing system permits researchers in the different

research fields to conduct rapid, parallel analysis in their

quest for active substances.

Biobanking

Reserved for future eventualities

Coordinator:

Prof Dr Peter SchirmacherHeidelberg

Biological samples constitute important materials for

infection research. The infrastructure “Biobanking”

provides DZIF researchers with samples of body fluids,

tissues and microorganisms. On this account, the DZIF

has established a biobanking platform with respective

technologies.

“The infrastructure ‘Biobanking’ has already supported

over 70 projects in different research fields,” sum-

marises Coordinator Prof Peter Schirmacher. Here, all

samples important to infection research are collected and

documented: the Helmholtz Zentrum München archives

fluid samples such as serum, plasma and urine while the

German Collection of Microorganisms and Cell Cultures

in Braunschweig stores pathogens and other micro-

organisms. The DZIF tissue bank at the Heidelberg

University Hospital collects infected tissue samples and

coordinates the entire biobanking infrastructure.

Long-term use for everyone

Equipped with a bar code, the samples are computer-

documented and stored at temperatures down to -196° C.

The samples are rapidly found electronically and, in part,

even withdrawn under robot control. Thanks to these

latest technologies, the DZIF biobanking platform can

provide safe, high-quality, precisely characterised and

standardised biomaterials. “Besides this, we advise re-

searchers on selection, transport and condition of the

samples, and provide support for project design,” says

Schirmacher. Supported by a laboratory information man-

agement system (LIMS), the biobanking platform is estab-

lishing a data and sample collection from transplant pati-

ents, for the National Transplant Cohort, an initiative of

the research field “Infections of the immunocompromised

Host”. This future project will broadly investigate the in-

fluence of infections on immunocompromised patients.

From 2015, approximately 800 patients per year will be

enrolled in the trial and registered in the biobank.

Accessible to everyone

In order to make materials available to as many re-

searchers as possible, the existing collections important

for research will be integrated into the DZIF Platform.

Additionally, other biobank stocks will be registered and

linked throughout Europe. Furthermore, the DZIF bio-

banking platform coordinates and organises the mee-

tings for the IT and biobanking working group within the

German Health Research Centres (DZG).

DZIF biobank samples are stored in large nitrogen tanks.

Bioinformatics

Harnessing information on infections

Biotechnological advances have revolutionised the diag-

nosis of infectious diseases: nowadays, genetic decoding

of microorganisms is possible in a matter of days, at de-

creasing costs and with increasing quality. However, the

challenge of processing the obtained data remains. The

DZIF infrastructure “Bioinformatics” helps researchers

make use of these data.

Participants in this infrastructure include Gießen Uni-

versity and the Helmholtz Centre for Infection Research

(HZI) in Braunschweig. Together, they have established

three service areas: “Information transfer”, which advises

and informs DZIF colleagues on specific questions; the

“Bioinformatics Resource Center” (BRC), which provides

analysis software tailored to the specific problems of the

researchers; and “Training activities”, where bioinforma-

ticians offer workshops to familiarise researchers with

tools for managing the technologies.

Making information and software accessible

“We have a data explosion,” says Prof Trinad Chakraborty,

Coordinator of the infrastructure, “and we need systems

that not only store data, but also make it interpretable for

everyone.” For this reason, the bioinformaticians estab-

lished a platform in 2014, which offers its services to DZIF

colleagues at “www.bioinformatics-platform.dzif.de”. It

includes a databank with thousands of sequenced com-

mon pathogen genomes and current outbreak strains. Be-

sides this, registered users can have access to specifically

tailored software, with which they can, for example, rapidly

compare typical virulence genes to strains in the databank

and identify epidemiological connections. In future, this will

enable calculations of risk potentials – using methods simi-

lar to those used for weather forecasts.

Making bioinformatics easier to understand

The infrastructure holds workshops to enable as many

scientists as possible to handle the service’s software in-

dependently. In these popular, hands-on workshops, DZIF

researchers learn how to manage the different functions,

and how to programme on their own. “We want to make

bioinformatics less daunting and make it a simple, user-

friendly technology for everyone,” Chakraborty hopes.

The workshops have been in high demand, also attracting

external researchers. This is why the range of courses of-

fered is being expanded and also being made available to

scholarship holders at the DZIF Academy.

DZIF Academy

Investing in future infection researchers

The best investment into infectious disease research is

to further the talents of the next generation. Promoting

junior researchers is therefore of major importance to

the DZIF. The DZIF Academy offers physicians and sci-

entists career opportunities in the fields of clinical infec-

tology, microbiology, virology, immunology and molecu-

lar medicine.

The virtually organised Academy promotes talents across

the DZIF partner sites. To this effect, it offers stipends to

medical students, for structured doctoral programmes.

It also has a clinical leave programme, to support young

hospital doctors who are interested in infectious disease

research. Additionally, an exchange programme enables

participants to gain insights into other DZIF establish-

ments, and maternity leave stipends assist female scien-

tists to return to their professions after having children.

Stipend holders can deepen their knowledge at the spring

and autumn school seminars – in both basic research and

clinical topics.

Excellent support for excellent researchers

In 2014 alone, the Academy supported 52 junior talents.

Furthermore, together with the scientific societies, it

awarded prizes to successful doctorates for the first

time, and also the DZIF Prize for Translational Infection

Research. Prof Ulrike Protzer, Coordinator of the DZIF

Academy is happy, “We had excellent stipend holders in

2014, as the awarded national and European research

prizes show – an example being the highly competitive

‘Young Investigator Award from the European Associa-

tion for the Study of the Liver’.” With this, she especially

highlights the scientific accomplishments of women at the

DZIF. “Maternity leave stipends are very supportive as

they give young mothers the freedom to combine having

children with having a career.”

Clinic, Child and Career

Dr Sandra Ciesek is also delighted with the support. The

DZIF is funding half of her salary during her two-year-long

maternity leave stipend. “This enabled me to start again

earlier,” the doctor says. Ciesek started working at the

Hannover Medical School when her daughter was four

months old: she now works mornings in the outpatient

clinic. In the afternoons, she has time for her hepatitis C

virus research, writes applications for new projects, and

instructs scientific staff. At around 4.00 pm, she picks up

her daughter from the crèche, and when the little one is

asleep in the evenings, Ciesek writes her publications.

“This work model is ideal, because I can divide my time,”

she says with a smile. “Another advantage is that it enables

me to stay connected with research.” And this paid off well

for Sandra Ciesek: as a young mother she was offered a

professorship.

The DZIF Academy makes young physicians and scientists enthusiastic about infection research.

Collaborations at the DZIF

United against Ebola

Scientists from research establishments, university hos-

pitals and federal research institutes collaborate at the

DZIF. During the most recent Ebola epidemic in West

Africa, DZIF colleagues experienced how important this

collaboration is and how much more can be achieved

when you are “united against infections”.

“DZIF members were on the ground from the start of

the Ebola epidemic in April 2014,” emphasizes Prof Martin

Krönke, Chairman of the DZIF Executive Board. The

epidemic spread so rapidly, that the WHO declared it

an international public health emergency in August. The

DZIF thereupon initiated a research consortium called

‘EBOKON’, now being funded by the German Federal

Ministry of Education and Research with 2.3 million Euros.

Ten research projects are being conducted – with topics

spanning from developing new vaccines against Ebola to

analysing the process of infection all the way through to

epidemiological questions.

Mobile telephones for monitoring contact persons

Up to then, Ebola outbreaks could be well-contained by

isolating ill people and the people they had come into

contact with. However, in the most recent epidemic,

monitoring and looking after these people meant having

to call on thousands of people, often in very remote areas.

In one of the EBOKON projects, DZIF researchers at the

Helmholtz Centre for Infection Research (HZI), together

with partners in Nigeria, the Hasso Plattner Institute and

the software producer SAP, are currently jointly develop-

ing an innovative IT system to monitor contact persons:

thanks to a new app, Nigerian health authority staff could

interview affected people via mobile phone, and record

and follow up the results in a central registry. “We tailored

our system to the needs of the local authorities and the

WHO,” says project leader Prof Gérard Krause from the

HZI.

International collaboration for vaccine trials

Another project clinically tested the vaccine candidate

“VSV- ZEBOV”. “We were in contact with the WHO, which

provided the vaccine and coordinated the preparations,

almost on a daily basis,” says Marylyn Addo, DZIF professor

at the University Medical Center Hamburg-Eppendorf

(UKE). She led the first clinical trials on healthy adults there.

The same vaccine trial was simultaneously conducted in

Gabon. DZIF colleagues from the Paul-Ehrlich-Institut

provided advice to the researchers for the approval pro-

cess. EBOKON Coordinator Prof Stephan Becker and his

team from the high-security laboratory at the Philipps-

Universität Marburg investigated whether test persons’

immune responses to the vaccine were sufficiently high

to be effective against live Ebola viruses. The results are

good: “The vaccine can potentially be used to protect

against Ebola,” says Becker.

Inconspicuous, but dangerous: Ebola viruses caused the 2014 Ebola epidemic in West Africa.

Increasing DZIF visibility, nationally and internationally

Looking back on the year 2014, the first thing we, in

the communication department, think about is Ebola.

The epidemic, which became apparent in spring 2014,

took up a large segment of our media work, and rightly

so. Over and over again, experts from the DZIF made

themselves available to journalists for questions and in-

terviews. They also provided further information about

Ebola research work, including the development of an

Ebola vaccine, which was of great public interest.

What does the DZIF accomplish? What fields of research

does it cover, and what is special about this network that

has united 32 (recently increased to 35) member estab-

lishments “under one roof” since it was founded? Provi-

ding answers to these questions and making the activities

externally visible – those are the most important responsi-

bilities of the Press and Public Relations Office.

Classic media work is essential

In 2014, the DZIF published two to three press releases

per month. Besides Ebola, the MERS coronavirus was

also a central issue, which the research field “Emerging

Infections” is also investigating intensively. Further-

more, there were research reports on tuberculosis,

novel antibiotics and antibiotic resistance, as well as

hepatitis and other infectious diseases – all interesting

topics that were taken up by the media.

Information accessible at the click of a mouse

Besides media work, continuously updating and develop-

ing the DZIF website plays a key role in the DZIF’s public

presentation. Here, different target groups can obtain re-

levant information with only a few mouse clicks. Around

42,000 visitors took advantage of the DZIF website’s ser-

vices in 2014.

In addition to presenting itself virtually, the DZIF is at-

tending more and more events and fairs to connect with

potential partners. Exhibition stands at the Permedicon

and the Congress for Infectious Diseases and Tropical

Medicine in Cologne, as well as the “Interscience Con-

ference on Antimicrobial Agents and Chemotherapy”

in Washington, contribute to making the DZIF known,

nationally and internationally.

Classic print media continue to play an important role in

the DZIF’s public presentation: with a focus on special

ideas and quality. To this end, an image brochure was con-

ceptualised at the end of 2014 and published in 2015. It

brings DZIF scientists working all over Germany closer

together in the so-called “Translation City”. The virtual

research centre was transformed into a city that accom-

modates for joint research activities on infectious disea-

ses. Short routes, intensive networking and an infrastruc-

ture for everyone – this is what the DZIF offers.

Strengthening the network with

internal communication

An association like the DZIF, which unites around 250

scientists and physicians at different partner sites

throughout Germany, can only function with good in-

ternal communication. The Press and Public Relations

Office supports internal communication with a quar-

terly newsletter and via the DZIF intranet, an exchange

platform equally accessible to everyone. Collecting and

channelling information from all parties, and serving as

an interface between research and the public is also im-

portant for a properly functioning network.

Face-to-face contact remains essential, despite the era

of Facebook, telephone conferencing and e-mailing.

The Annual Meeting 2014 demonstrated this, where

around 250 DZIF members came together for three

days to present the progresses and objectives of their

research activities, as well as for discussions. This lively

conference which took place in Braunschweig, the Main

Office’s location, impressively highlighted the DZIF’s

accomplishments to date.

External Collaborations

Numerous associated partnerships and other exter-

nal collaborations reinforce the DZIF’s position as a

top-class institution in the field of infection research.

DZIF’s associated partners

Charité – Universitätsmedizin Berlin

Charité – Universitätsmedizin Berlin is partner in a stu-

dy on the intelligent use of antibiotics (ATHOS: antibiotic

therapy optimisation study). It investigates whether inter-

ventions for targeted antibiotic use in hospitals (antibiotic

stewardship see University Medical Center Freiburg) and

in practices (Charité) influence the number of new cases

of infection with certain antibiotic-resistant bacteria. A

method which was developed in the new module “ATHOS-

MRE-Surveillance” at the Charité is being used to monitor

the multidrug-resistant organisms. In 2014, hospital staff

from six university hospitals were trained to use this tool

and the studies were initiated. Additionally, the Charité

held training events for practice-based physicians. Further-

more, the Charité organised a multicentre study on

infection prevalence at admission, running under ATHOS.

Friedrich-Loeffler-Institut, Riems

(DZIF member since June 2015)

The Friedrich-Loeffler-Institut (FLI) is partner in a col-

laborative project aimed at the early detection of patho-

gens, particularly those transmitted from animals. The FLI

provides the necessary blood and tissue samples, as well

as nucleic acid preparations, from both domestic and wild

animals. Especially the unique laboratory and animal tes-

ting facilities, with biosafety levels 2 to 4, make the FLI an

important partner for the DZIF.

hepatitis research, and provides a platform for conducting

clinical trials. The DZIF can use the infrastructures and

cohorts for its projects. Current research activities are

focussing on hepatitis B, C, D and E. In 2014, a project on

hepatic encephalopathy was initiated together with the

German Liver Foundation. We report on the establish-

ment of a hepatitis D registry on page 15.

Goethe University Frankfurt am Main

A project focussing on hepatitis, in which clinical cohorts

are being established, is currently ongoing at the Goethe

University Frankfurt am Main. Blood samples taken

from patients before therapy or after therapy failure are

available to all collaborating partners. The clinical data,

along with viral and host gene analysis and phenotypic

results, are being analysed and recorded in an online-

based tool. This tool aims at improving the evaluations

of courses of disease and treatment responses, and to

tailor individual treatment.

Gottfried Wilhelm Leibniz Universität Hannover

DZIF scientists recently discovered a completely new

substance class called cystobactamides, which is effec-

tive against difficult-to-treat gram-negative bacteria. A

project at the HZI aims to develop these cystobactami-

des further, so that they can undergo testing as potential

antibiotics in preclinical trials. Scientists at the Leibniz

Universität Hannover succeeded in conducting the

first total synthesis of cystobactamide C, which paves

the way to the synthesis of further cystobactamide

variations.

Hans Knöll Institute, Jena

The Hans Knöll Institute (HKI) is a leading institute for

natural compound research. As an associated partner, it

provides the DZIF with natural compounds, particularly

fungi. A project is investigating the pharmacodynamics of

corallopyronin A, a natural product that has already been

successfully tested against the filariasis pathogen and is

undergoing preclinical evaluations. The HKI is largely re-

sponsible for its biosynthesis; the production was further

optimised in 2014.

Max Planck Institute for Informatics, Saarbrücken

At the Max Planck Institute for Informatics in Saarbrü-

cken, data on hepatitis C patients who are undergoing

treatment with new antiviral agents, is being collected

as part of a DZIF project. Sequencing, analysis and in-

terpretation of patient and viral genes, along with other

parameters, will be used to evaluate the course of treat-

ment. In Saarbrücken, the analysis results are being used

to further develop an online-based tool, the so-called

Geno2pheno[HCV]. The analysis results are therefore

freely accessible online, and can be used to support de-

cisions for personalised treatment.

Robert Koch Institute, Berlin

(DZIF member since June 2015)

The DZIF and the Robert Koch Institute (RKI) collaborate in

many areas. A few examples: In the research field “Emerging

Infections”, the RKI is supporting strategic partnerships be-

tween research establishments, hospitals and pharmaceu-

tical companies. In clinical trials, they are jointly developing

clinical guidelines. The DZIF has access to the RKI’s new data-

bank “HIOBs” for its HIV research; the software has been

optimised and is now being implemented at the partner sites.

University Medical Center Freiburg

In a project with the University Medical Center Freiburg

on infections of the immunocompromised host, scientists

are looking to find genetic factors associated with in-

creased susceptibility to infection. They intend to find bio-

markers that allow better infection control, and are con-

centrating on fungal infections in immunocompromised

patients.

A second DZIF project is investigating the more targe-

ted use of antibiotics (see also Charité). In 2014, a pilot

project impressively showed that antibiotic stewardship

(ABS) strategies can be implemented successfully. In an

intensive ABS programme in internal medicine at the

University Medical Center Freiburg, the use of important

broad spectrum antibiotics was reduced by approximately

30 percent in one year. The programme in Freiburg aimed

at reducing the use of cephalosporins and fluoroquinolo-

nes while encouraging the use of penicillin derivatives.

at developing new treatment strategies against gastro-

intestinal infections. In many cases, the commonly used

antibiotics harm the normal gut flora and can lead to compli-

cations. In Münster, the scientists are working on preventing

the complications associated with EHEC.

A second project is working on hospital pathogens, par-

ticularly multidrug-resistant Staphylococcusaureus in the

nasal region. Here, new lytic phage proteins for targeted

treatment are being investigated. Their efficiency and

specificity will be analysed in Münster.

German Health Research Centres

The main objective of the German government’s

health research programme is to develop more effec-

tive ways to combat widespread diseases. The ground-

work for this has been laid at federal and state levels

with the establishment of German Health Research

Centres (DZG) as long-term, equal partnerships

between non-university research institutes and uni-

versities with medical centres.

These German Health Research Centres pool all of their

existing expertise, thereby greatly helping to close know-

ledge gaps and improve prevention, diagnosis and therapy

of their respective diseases. The research policy ensures

close collaboration between basic research and clinical re-

search, always specifically oriented on the indications and

the patients’ needs. Close networking and the expansion

of existing research structures will allow faster transfer of

research results into clinical practice (translation).

The strategic cooperation of leading scientists in the

German Health Research Centres promotes Germany to

a high-ranking scientific location and increases its attrac-

tiveness to young scientists in Germany and around the

world.

2009 saw the foundation of the “German Centre for

Neurodegenerative Diseases” and the “German Centre

for Diabetes Research”. Alongside DZIF, the “German

Center for Cardiovascular Research”, the “German

Consortium for Translational Cancer Research” and the

“German Center for Lung Research” were launched in

2012.

From the outset, the six German Health Research

Centres have collaborated closely in order to share their

findings and exploit synergies.

In focus at the DZG: combatting widespread diseases more effectively.

Organisation and bodies

Structure of DZIF

The General Assembly is the central decision-making organ of DZIF. It comprises representatives of the member research establishments

of the DZIF. The General Assembly elects the members of the Executive Board and the Executive Director, and decides on the allocation of

funds to the research fields and infrastructures (TTUs and TIs).

General Assembly

The Commission of Funding Authorities is

made up of the Federal Government and

respective states (Länder) and decides on

important matters of finance, organisa-

tion and personnel. The Executive Board

and the Managing Director report to the

Commission on all funding measures.

Commission of Funding Authorities

The Executive Board represents the

DZIF externally. It implements the

resolutions and tasks assigned by the

General Assembly and is responsible for

routine administrative affairs.

Executive Board

The association is supported by the

Scientific Advisory Board consisting of

internationally renowned experts from

the field of infection research. The Scien-

tific Advisory Board advises the Executive

Board and General Assembly on all

scientific and programme-related matters.

The Main Office is located in Braun-

schweig and supports the Executive

Board in its work. Its duties include

organising research initiatives and

coordinating DZIF’s press and public

relations activities.

Internal Advisory Board

The members of the Internal Council are

DZIF scientists representing all areas and

locations of the centre. The council

advises the Executive Board on all scien-

tific, programme-related and technical

matters and performs representative

duties.
