Agarose gel electrophoresis of PCR products of representative isolates.

Notes: The mecA gene is indicated by the amplification of 533 base pair products. Lanes 6 and 9 are positive for mecA, as indicated by the 533 base pair PCR product. Lanes 1–5, 7, 8, 10–21, 24, and 25 were negative for mecA. Lane 22 was the MRSA-positive control (NCTC 119040), lane 23 was the negative control (water), and lane M was the molecular weight size marker.

Abbreviations: PCR, polymerase chain reaction; MRSA, methicillin-resistant Staphylococcus aureus; NCTC, National Center for Type Cultures; M, molecular weight.
