Performance of MicroScan WalkAway and Vitek 2 for detection of oxacillin resistance in a set of methicillin-resistant Staphylococcus aureus isolates with diverse genetic backgrounds.
Of 104 genotypically diverse methicillin-resistant Staphylococcus aureus (MRSA) isolates tested with the MicroScan WalkAway (Pos MIC 24 panel) and Vitek 2 (AST-P549 card) systems, 7 and 6 isolates, respectively, showed an oxacillin MIC of < or =2mg/liter. Most of these MRSA isolates were community acquired. However, if the cefoxitin screen of AST-P549 was also considered, MRSA detection failed for only one isolate.
