Construction and oxacillin susceptibilities of mecA1 overexpression strains. The mecA1 gene from S. sciuri NWAF26 was introduced into the methicillin sensitive S. aureus strains RN4220 and Newman by shuttle vector pSE1, respectively. (A) The expression level of mecA1 were measured by qRT-PCR. (B) Oxacillin susceptibilities were determined using MH agar with 2% NaCl containing 1 mg/L oxacillin. NWAF26R was taken as a positive control.
