OBJECTIVE: To evaluate accuracy, cost-effectiveness and ease to perform different phenotypic methods i.e. Cefoxitin 30 microg disc, Oxacillin 1microg disc and Oxacillin agar screening plate (6microg/ml ) for early and accurate identification of MRSA by comparing with the detection of mec-A gene in our clinical isolates.
DESIGN: A comparative study.
PLACE AND DURATION OF STUDY: Clinical samples submitted in the Clinical Microbiology Laboratory at Aga Khan University Hospital, Karachi, from 1st August to 31st October 2006.
MATERIAL AND METHODS: Out of 200 clinical samples, conventional Polymerase chain reaction (PCR) was done on 62 pure biochemically identified S. aureus …
