Methicillin resistant staphylococci do not respond to
β-lactam antibiotics because:
A. They produce a β-lactamase which destroys
methicillin and related drugs
B. They elaborate an amidase which destroys
methicillin and related drugs
C. They have acquired penicillin binding protein which has low affinity for β-lactam antibiotics
D. They are less permeable to β-lactam antibiotics
