Part B: Brief Answer – Gram-positive and Gram-negative bacteria each possess unique cell wall or plasma membrane features that cause them to respond differently to certain antimicrobial treatments. (9 points)

a. Name one antimicrobial drug that works specifically on each group but not the other, and explain the rationale for why it is effective for one group but resisted by the other.

b. Name one physical or chemical treatment that works specifically on each group but not the other, and explain the rationale for why it affects one group but not the other.

Therefore, you would need to provide four antimicrobial treatments in total.

·  One drug that works specifically on Gram-positive but not Gram-negative

·  One drug that works specifically on Gram-negative but not Gram-positive

·  One treatment effective specifically on Gram-positive but not Gram-negative

·  One treatment effective specifically on Gram-negative but not Gram-positive
