Yes.. but: I would be wary with ampicillin as most strains are beta-lactamase + . Unless, the lab test shows penicillin or ampicillin sensitivity I will not use this drug to treat staph infection blindly. A better relative drug option is amoxicillin-clavulanic acid, the latter component inhibits the beta-lactamase enzyme. Cloxacillin and amox-clav will act against Methicillin sensitive staph but not MRSA.
