Exposure to oxacillin subinhibitory concentrations and in vitro induction of resistance expression in heteroresistant and non-heteroresistant oxacillin-susceptible mecA-positive Staphylococcus aureus (OS-MRSA)
H. C. C. Povoa, D. B. Schimidt
The study shows that exposure to oxacillin sub-MICs induces homoresistance in both heteroresistant and non-heteroresistant OS-MRSA strains, increasing β-lactamase production and reducing penicillin zone inhibition.
