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.
