Robert Tatsis r.tatsis@uu.nl

This hour

Theory•Introduction to bacteria in hospitals•Didactical background of this assignment

Practice•Identification of bacteria•Discussing answers and didactics

Main question:What characteristics of the material are suited for promoting talent development?

A module for grade 9 studentsAt school•Making preliminary assignment “the structure of bacteria”•Lot of schools; no biology in grade 9

At the campus - day 1•Introduction to subject (50 min)•Choosing which subject students want to specialise in

At the campus - day 2•Specialisation on specific topic•Building a model of a bacterium •Designing an hypthetical antibiotic

SA

• Staphylococcus Aureus

• 1 in 3 people is a carrier of S. Aureus

• Ofter without being sick

MRSA

• Meticillin-resistant Staphylococcus Aureus

• Treatment antibiotics SA: 2 – 55 euro

• Treatment antibiotics MRSA: 601 – 882 euro– If they work!– More side effects

MRSA causes

• Pneumonia

• Wound- and skininfection (pictures will follow)

• Bone infections

• Sepsis (for example toxic shock syndrome)– Can be lethal

Folliculitis

Impetigo

Bulleus impetigo

Staphylococcal Scalded Skin Syndrome

Abces

Carbuncle (multiple boils)

Ecthyma

How do we test on MRSA?

• Doctor takes a monster from nose, throat and wound (if wounded)

• Mostly patients who have been to hospitals abroad (why?)

How do we test on MRSA?

• Cultues grow on petri dishes with antibiotics– Practical assignement on

this theme

Automatic: culture passes antibiotics

In a big machine (Phoenix)

Looking at a genetic level

What do do when infected?

• Patient must be isolated

• Only contact through airlock and with facemasks

• Try to treat with the expensive antibiotics
