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

Required

Select the possible strategies that antibiotics use to kill bacteria

Required
1

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


Required
5

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.

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

Required
5

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.
