(Select all that apply) A microbe acquires antibiotic resistance by which means?

 



Correct Answer: ["D","E"]

A microbe acquires antibiotic resistance by transferring DNA coding to other bacteria or by spontaneous mutation in the microbial genome.

These genetic changes allow the microbe to survive the effects of the antibiotic and pass on the resistance to its offspring.

Choice A is wrong because the host does not develop medication resistance, but the microbe does.

Choice B is wrong because the minimum bactericidal concentration (MBC) is the lowest concentration of an antibiotic needed to kill 99.9% of bacteria, not a mechanism of resistance.

Choice C is wrong because incorrect dosing does not cause ribosome mutations, but may promote the emergence of drug-resistant microbes by exposing them to suboptimal levels of the antibiotic.
