The primary mechanism of resistance to this antimicrobial class is modification by mutations encoding single amino acid changes in these targets. What antibiotic class is this?
A) Macrolides
B) Quinolones
C) Peptidoglycans
D) Aminoglycosides

Question

Quizplus · Accepted Answer

The primary mechanism of resistance to quinolones is modification by mutations encoding single amino acid changes in the DNA gyrase or topoisomerase IV targets. Macrolides are primarily resistant by efflux pumps and modification of their binding site. Peptidoglycans are not an antibiotic class, but rather a component of the bacterial cell wall. Aminoglycosides are primarily resistant by enzymatic modification and efflux pumps.
