The main reason why methicillin-resistant Staphylococcus aureus
(MRSA) strains are resistant to methicillin and nafcillin is:
(A) they produce β-lactamase that degrades the antibiotics.
(B) they have altered penicillin-binding proteins that have
reduced binding of the antibiotics.
(C) they have mutant porin proteins that prevent the antibiotics
from entering the bacteria.
(D) they have plasmid-encoded export proteins that remove the drug from the bacteria
