Abstract:
We evaluated MRSA-CI agar (Kyokuto Pharmaceutical Industrial Co., Ltd.) and BD BBL CHROMagar MRSA II agar (BD Japan) for the detection of Methicillin-resistant Staphylococcus aureus (MRSA). We used 129 specimens in this study. The positive rate of MRSA-CI agar was 19.4% (25/129 samples), whereas BD BBL CHROMagar MRSA II was 17.8% (23/129 samples). It is suggested that MRSA selective agar medium including enzyme substrate compounds is a useful medium to detect MRSA.
