Question 9
9.

Where does the initial "seeding" (beginning) of your microbiome come from?

Question 10
10.

How does your microbiome help "educate" your immune system?

Question 11
11.

A healthy gut microbiome has very little diversity (different types of bacteria) - it is better to have only one or a few types of bacteria in the gut.

Question 12
12.

What might explain the huge increase in diseases like food allergies, asthma and diseases of the gut like IBS or colitis? (select all that are correct)

Question 13
13.

What would be the easiest way to make your gut microbiome function better in making you healthy?

Question 14
14.

Select the possible strategies that antibiotics use to kill bacteria

Question 15
15.

Which antibiotic is most effective at killing this type of bacterium?


Question 16
16.

Imagine as a doctor you have sampled the bacterium making your patient sick and grew the bacterium (the orange color lawn) on a petri dish. You then test 5 antibiotics to see which to prescribe to your patient. From the image that shows the results of your testing below, which antibiotic will you choose to give to your patient? Explain how you made your choice.

Question 17
17.

What is a multi-drug resistant bacteria ("superbug")?

Question 18
18.

Use this image to explain how a population of bacteria become resistant to an antibiotic. Start with the image on the left and move from left to right explaining what is happening to the bacterial population. Make sure you use vocabulary like mutation, selection and reproduction.

9 (makes proteins)
cell wall
8 (extra small loop of DNA)
cell membrane
2
ribosome
6 (helps bacteria stick to surfaces and do conjugation)
nucleoid/bacterial chromosome
10
flagellum
7 (majority of bacteria genome)
pilus
1
plasmid
by drinking lots of sugary drinks
by eating/drinking more pre-biotics like fruits and vegetables and more pro-biotics like fermented foods
