Decreased affinity of PBP3 to methicillin in a clinical isolate of Staphylococcus epidermidis with borderline resistance to methicillin and free of the mecA gene.
Analysis of the antibiotic binding capacity of penicillin-binding proteins (PBPs) in a group of clinical isolates of Staphylococcus epidermidis suggests that the increased level of resistance to methicillin (MIC 4.0 microg/ml) in an isolate free of the mecA gene is due to the decreased binding capacity of PBP3.
