A diabetic patient developed cellulitis due to staphylococcus aureus, which was found to be Methicillin resistant on the antibiotic sensitivity testing. All of the following antibiotics will be appropriate EXCEPT________________?

Correct answer: B. Imipenem

  • A. Vancomycin
  • B. Imipenem
  • C. Teichoplanin
  • D. Linezolid

Explanation

MRSA should be treated with agents active against resistant Gram-positive cocci, such as vancomycin, teicoplanin or linezolid. Imipenem is a beta-lactam and is generally ineffective against MRSA because of the altered penicillin-binding protein PBP2a.
