question 51

Multiple Choice

Please select the True statement regarding bacterial resistance to antimicrobials.

• A) Gram-positive bacteria are intrinsically resistant to certain medications because the lipid bilayer of their outer membrane prevents the molecules from entering.
• B) Intrinsic resistance  generally occurs through spontaneous mutation or horizontal gene transfer.
• C) The genes for antimicrobial resistance are often carried on fertility plasmids (F plasmids).
• D) Mycoplasma species lack a cell wall, so they are resistant to penicillin that interferes with peptidoglycan synthesis. This is an example of intrinsic resistance.
• E) Acquired resistance is very limited because microorganisms cannot evolve, so are incapable of developing mechanisms to avoid the effects of medications.
