<prompt> Amoxicillinclavulanic acid is active against the following organisms EXCEPT:Methicillin resistant Staph. aureusPenicillinase producing Staph. aureusPenicillinase producingN. gonorrhoeab-lactamase producing E.coli  <response>: Ref: KDT 6e p702, 703 Staphylococcus aureus develops resistance to methicillin by acquiring altered penicillin binding proteins that have low affinity. No b-lactam antibiotic is effective against MRSA. Clavulanic acid is n inhibitor of b-lactamase. It can restore the sensitivity of penicillins against the organisms who have developed penicillinases.
