Lineage-associated genomic features and phenotypic heterogeneity in clinical borderline oxacillin-resistant Staphylococcus aureus
ABSTRACT Borderline oxacillin-resistant Staphylococcus aureus (BORSA) represents a mecA/mecC-negative phenotype characterized by oxacillin minimum inhibitory concentrations (MICs) of 1–8 mg/L. The molecular basis of this resistance, particularly regarding lineage-associated differences in induction profiles, remains in...
