Suspected colonies of methicillin-resistant Staphylococcus aureus (MRSA) on chromogenic, MRSASelect (BioRad) medium were confirmed using routine microbiological methods, and a multiplex real-time PCR (n = 108). Although the specificity of MRSASelect assessed at 24 h of incubation was much higher than that of 48 h (91.4 vs. 60 %), extending the incubation time to 48 h, along with PCR confirmation, increased the total number of true positive samples by 27.8 %. These results provide a cost effective method for sensitive and specific detection of MRSA.
