Comparison of Automated Antimicrobial Susceptibility Testing Systems To DetectmecC-Positive Methicillin-Resistant Staphylococcus aureus

Methicillin resistance in Staphylococcus aureus is classically mediated by the mecA gene carried on a mobile genetic element, called staphylococcal cassette chromosome mec (SCC mec ). mecA encodes an additional penicillin binding protein, named PBP2a, with low affinity for all beta-lactams except
