Whether an antimicrobial is broad spectrum or narrow spectrum depends on its
mode of action. For the following 2 hypothetical drugs, predict whether they are
broad spectrum or narrow spectrum. Explain your reasoning:
4.
a. Drug A interferes with peptidoglycan synthesis -
b. Drug B interferes with 70S ribosome function-
c. Drug C interferes with synthesis of a vitamin –
What kind of drug might be made out of an antimicrobial peptide and describe an advantage it would have over a drug like penicillin?
We have many antimicrobial drugs to treat bacterial infections, but very few for viruses. Why is it so difficult to treat viral infections? Hint: What would the targets for the drugs be?
