Multicenter Evaluation of a Modified Cefoxitin Disk Diffusion Method and PBP2a Testing To Predict mecA -Mediated Oxacillin Resistance in Atypical Staphylococcus aureus

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...

Evaluation of oxacillin and cefoxitin disk diffusion test for routine detection of methicillin resistant Staphylococcus aureus.

Evaluation of Cefoxitin Disk Diffusion Test for Routine Detection of Methicillin-resistant Staphylococcus Aureus

Background and Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of nosocomial and community acquired infections. Detection of MRSA in laboratories is very important for treatment and appropriate infection control. The aim of this study was to evaluate cefoxitin disk diffusi...

Detection of Methicillin Resistant Staphylococcus aureus (MRSA) by CHROMagar Versus Cefoxitin Disk Diffusion Method

 Methicillin resistant Staphylococcus aureus (MRSA) has been emerged as a nosocomial and community acquired pathogen worldwide. There are many challenges for laboratory detection of MRSA. The aim of this study was to compare different phenotypic methods with PCR based method as a gold standard for detection of mecA gene to detection of MRSA. A total of 220 clinical isolates of S. aureus which w...

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...
