What environment stimulates evolution of drug-resistant pathogens?
A)presence of an enzyme called penicillinase
B)colonization of host
C)pathogens without cell walls
D)excess antibiotics

Question

Quizplus · Accepted Answer

Excess antibiotics create a selective pressure that favors the survival and proliferation of bacteria with randomly occurring mutations that confer resistance to the antibiotic. Over time, these resistant bacteria become more prevalent and can lead to the evolution of drug-resistant pathogens. The presence of penicillinase, colonization of a host, and pathogens without cell walls do not necessarily stimulate the evolution of drug-resistant pathogens.
