Fig. 1From: Phenotypic and genotypic characterisation of multiple antibiotic-resistant Staphylococcus aureus exposed to subinhibitory levels of oxacillin and levofloxacinHydrolyzing activity of extracellular β-lactamase a and membrane-bound β-lactamase b produced by Staphylococcus aureus KACC 10778, S. aureus ATCC 15564, and S. aureus CCARM 3080 exposed to a half MIC of oxacillin or levofloxacin. Means with different letters (a–c) on the bars are significantly different at p < 0.05Back to article page
