Performance of a New MicroScan WalkAway PC30 panel and disk diffusion method for detection of oxacillin resistance in Staphylococcus spp.
نویسندگان
چکیده
The performance of the MicroScan WalkAway PC30 panel for detection of oxacillin resistance was evaluated by use of a collection of 420 staphylococcus isolates. The addition of a cefoxitin test (4 mg/liter) to the oxacillin MIC determination increased its raw performance for Staphylococcus aureus; additional data were required for coagulase-negative staphylococci.

Detection of Oxacillin Resistance in Staphylococcus aureus: Comparison of Phoenix Oxacillin and Cefoxitin MICs, MicroScan Oxacillin MIC, Oxacillin and Cefoxitin Disk Diffusion, and mecA Gene Detection
BACKGROUND. Phenotypic tests for detection of mecA containing staphylococci have been challenged. Cefoxitin (FOX) disk diffusion (DD) has been reported to more accurately predict mecA gene presence than oxacillin (OX) DD. The Phoenix instrument rapidly provides identification and susceptibility data and it is of interest to determine if an experimental panel containing OX and FOX could accurate...
متن کاملPerformance 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 ...
متن کاملDetection Of Methicillin Resistance In Staphylococcus Aureus By Disk Diffusion And PCR Methods
Background and Objective: Methicillin resistance in Staphylococcus aureus is an increasingly important clinical problem. A chromosomal gene, mecA, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in Staphylococcus aureus. We evaluated the validity of disk diffusion test by using oxacillin, methicillin an...
