Why is microbiome diversity important?
Microbiome diversity is important for maintaining a healthy immune system, aiding in digestion, and protecting against harmful bacteria.
Microbiome diversity increases the risk of infections.
Microbiome diversity only affects digestion.
Microbiome diversity has no impact on overall health.
How does the microbiome affect human health?
The microbiome affects human health through various mechanisms such as digestion, immune system function, and protection against bacteria.
The microbiome only affects immune system function, not digestion or protection against pathogens.
The microbiome only affects mental health, not physical health.
The microbiome has no impact on human health.

Humans and mice have the same exact microbiomes.
True
False
Which bacteria is evidenced in week 7 that wasn't there week 5?
Space
C. difficile
other
E.coli
In Experiment 1, there were two groups of 20 ________ that were experimented on.
mice.
worms.
bacteria.
humans.
In Experiment 1, the two groups of mice were given __________ to see if they would get sick.
C.diff
C.jejuni
Salmonella
Actinobacteria
Why did the group of mice with spaces and gaps in their microbiome get sicker than the other group?
Spaces in a microbiome allow bad bacteria like Salmonella or C.diff to grow and expand.
They were sick mice when we started the experiment.
They were supposed to get sick from Salmonella.
Good bacteria weren't able to save them from C.diff.
If a human has taken antibiotics for an infection, what dangerous situation could occur?
They could get diarrhea.
They could get Covid or the flu.
They might have to get more antibiotics.
There could be spaces or gaps in their microbiome.
What is one thing that good bacteria in a healthy and full microbiome do?
Good bacteria keep people warm like coat because they cover a person all over.
Good bacteria feed people antibiotics like C.diff and Salmonella.
Good bacteria become bad when the bacteria die like C.jejuni.
Like a shield, good bacteria protect people from bad bacteria because the good bacteria cover every space of a humans body.
During Week 7, why did Patient 23 get a fecal transplant instead of more antibiotics?
It didn't matter how we treated Patient 23. Both would have worked.
Antibiotics restore healthy bacteria to a person's microbiome.
Healthy and full microbiomes depend on fecal transplants for more good bacteria.
Antibiotics would have killed all of the bacteria. The fecal transplant filled in the spaces with good bacteria.
Which is an example of normal and good bacteria in a human microbiome?
Salmonella
C. difficile
C.jejuni
Bacilli
Which is an example of normal and good bacteria in a human microbiome?
C. jejuni
C. difficile

Epsilonproteobacteria
What are Bacteria?
Tiny organisms that are made of many cells.
Tiny organisms that are made of a single cell.
