The Clinical and Laboratory Standards Institute (CLSI) is a not-for-profit membership organization that brings, 9/12/2013В В· Oxacillin was only reliable for the detection of mecC-MRSA if MICs were determined using AD with Columbia agar containing 2% NaCl. The lower ability of oxacillin to detect mecC-MRSA isolates is most likely a result of a 4-fold higher affinity of the mecC-encoded PBP2a var for oxacillin (i.e. lower MICs) compared with cefoxitin. 12.
