Microbiome: Definition and background

4

What does “microbiome” mean?

“The microbiome is defined as the collective genomes of the

microbes (composed of bacteria, bacteriophage, fungi, protozoa,

and viruses) that live inside and on the human body.”

-NIH, 2012

Microbiota refers to the collection of microbial organisms that

inhabits a certain environment

Metagenomics is the study of the collective genomes of

microorganisms from a sample without cultivation (Lederberg and

McCray 2001, The NIH HMP Working Group)

Kuczynski et al. Nature Reviews Genetics 13, 47-58 (January 2012)

Human Microbiome Project

Microorganisms cluster by body siteCataloguing efforts by the NIH Human Microbiome Project suggest:

• ~10,000 organisms live with us

• Second genome: outnumber

our own genes 150:1

Identifying microbiota in healthy individuals revealed:

• Different body sites have

unique communities

• Race, age, gender, weight or

ethnicity have an effect

Earth Microbiome Project

Multidisciplinary effort to survey the microbial composition of diverse environments across the globe:

• Aims to process 200,000 samples from these different biomes

• Generate a database of microbes and their gene products

• Will greatly enhance our understanding of the roles microbes play in ecology

• Will expand our understanding of microbial metabolism and gene products

• Estimates of bacterial diversity1:

• 160 distinct types of bacteria in 1 ml of ocean water

• 6,400 – 38,000 types of bacteria in 1 gram of soil

These are just estimates for bacteria alone; one still needs to consider viruses, archaea

and fungi

National Academy of Sciences 99 (16): 10494–10499.

Sample to Insight

Sample preparation requirements for successful microbiome studies

There are several areas where sample prep inefficiencies can bias a

microbiome/metagenomics study:

• Co-purification of small molecule inhibitors of amplification reactions (e.g., PCR)

Decreases efficiency of amplification or can inhibit library prep reactions

• Insufficient cell lysis

Bias downstream analysis toward ‘the easily disrupted’ population(s)

• Reproducible isolation of high quality nucleic acids

• Poor nucleic acid quality, extensive shearing

• Insufficient solubilization of analyte(s) of interest/separation from interacting cellular

components

• Unintended precipitation of nucleic acids via complexation with matrix-derived

metals, bioactive amines

• Insufficient homogenization of sample matrix (to dislodge/disrupt cell:substrate

interactions)

Sample-derived PCR/RT-PCR inhibitors

In the process of breaking open cells to

release nucleic acids, amplification

inhibitors are also released.

*Other examples for additional matrices given in Rådström, P. et al. (2004) Pre-PCR processing: Strategies to

generate PCR-compatible samples. Mol. Biotechnol. 26, 133–46.

Inhibitors include humic/fulvic acids in soil,

polysaccharides/polyphenolics in plants

and bile, bilirubin and heme in stool*

Soil

Distinct, diverse microbial species populate the soil of temperate, desert, tropical and arctic

regions

Soil biodiversity is influenced pH and the chemical composition of soil organic matter within the

soil environment

Isolation of nucleic acids from soil is complicated by the large amounts of humic acids

contained within

16S OTU and taxonomic assignment workflow

• Includes quality filtering

• For OTU picking, sequences were mapped

against the greengenes data base and clustered

at 97% identity

• Unmapped sequences were then clustered de

novo

• Results shown are summarized at the genus

level

• Highly customizable outputs

• Differential Abundance analysis (not shown)

Alpha and Beta Diversity Workflow

• Young individuals have a higher alpha diversity

compared with old as measured by observed

OTUs

• Other metrics include, Shannon and Simpson

Diversity, phylogenetic diversity

• Highly customizable output

• Beta diversity: unweighted UniFrac Analysis

• Young and old gut communities are significantly

different. P = 0.047 Permanova analysis,

corrected for multiple comparisons

• Other metrics include weighted UniFrac,

gneralized UniFrac, Bray-Curtis, Euclidean

• Highly customizable outputs

WGS read mapping and Taxonomic assignment workflow

• Includes quality filtering and read merging

• The taxonomic profiler maps each read

against the chosen database

• Output is an abundance table including

graphical representation

• Highly customizable output

• Graph shown at left is summarized at the

genus level

• CLC Microbial Genomics Pro Suite can also

alpha and beta diversity analyses (not shown)

WGS De novo assembly and Functional assignment workflow

• Includes quality filtering

• De novo assembly of reads, identification and

annotation of genes and coding sequences

• Perform functional and statistical analyses

• Highly customizable output

• Samples are clustered by functional similary

using Euclidean distances

• CLC Microbial Genomics Pro Suite can also

perform taxonomic assignment (not shown)
