mecA produces an altered penicillin-binding protein (PBP2a) that has low affinity for beta-lactam antibiotics, including methicillin, oxacillin, and most cephalosporins. Its presence makes Staphylococcus aureus methicillin-resistant (MRSA) — a major hospital and community pathogen.
mecA detection is a key component of molecular susceptibility testing in respiratory, wound, and bloodstream infection workups. Identifying mecA rapidly allows providers to choose effective antibiotics — typically vancomycin, linezolid, or daptomycin — instead of beta-lactams that would fail. The gene is also detected in some coagulase-negative staphylococci. Sample type depends on the source — typically a swab, tissue, or culture isolate.
