Introduction to why knowing the antibiotic sensitivity would be important to know for a particular microbe.
Describe your microbe (the specific one you got, whether S. aureus, E. coli, P. mirabilis, or P. aeruginosa. In your description, make sure to include, at minimum, gram staining, shape, size, natural reservoir, human diseases caused by this microbe, special features (like fimbriae, capsule, etc.), and the like. This should be a significant paragraph or two and should include the full taxonomic name (Domain Kingdom Phylum Class Order Family Genus species <-- this is the correct format and that is important). You have 12 antibiotics. Describe all 12 (not just the ones that worked). Provide the specific mechanism of action of each. Here's where it can get tricky and you can lose points. All antibiotics are used to kill bacteria or at least slow their growth. So that cannot be your answer, at least not for credit.
