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
نویسندگان
چکیده
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 accurately detect OX resistance.

Detection 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...

Detection of the mecA gene or PBP2a is considered the gold standard for detecting mecA-mediated methicillin resistance in staphylococci. Among available phenotypic methods, the Clinical and Laboratory Standards Institute (CLSI) has introduced the cefoxitin disk diffusion (DD) test for predicting the presence of mecA in S. aureus and CoNS, which is preferred over the oxacillin DD test. Automated...

Staphylococcus pseudintermedius is a coagulase-positive species that colonizes the nares and anal mucosa of healthy dogs and cats. Human infections with S. pseudintermedius range in severity from bite wounds and rhinosinusitis to endocarditis; historically, these infections were thought to be uncommon, but new laboratory methods suggest that their true incidence is underreported. Oxacillin and ...
