Oxoid Brilliance MRSA Agar and bioM?rieux MRSA ID medium were evaluated for their ability to identify meticillin-resistant Staphylococcus aureus (MRSA) in clinical samples. Nasal and throat samples (n = 629) were taken from veterinarians and their household members. The sensitivities of Brilliance MRSA Agar and MRSA ID medium after 20 h of incubation were 63.6 and 64.5 %, and the specificities were 94.1 and 99.4 %, respectively. After an enrichment step, the sensitivities increased to 96.3 and 97.2 %, but the specificities decreased to 88.7 and 98.5 %, respectively. Brilliance MRSA Agar and MRSA ID medium are both sensitive methods for the screening of MRSA in combination with broth enrichment, but positive results require confirmation.
