The mecA gene was identified by testing the polymerase chain reaction. Results: There was a 90.1% positive finding of Staphylococcus aureus. The frequency of oxacillin resistance was 9.8%; all samples were sensitive to vancomycin.

WebThe following tests were performed: oxacillin screening agar (plates were inoculated with 4% NaCl and 6 mg/L of oxacillin), cefoxitin disc diffusion test (30 ug) and PCR to amplify the mecA gene. Results. The mecA gene was detected in 165 out of 331 S. aureus isolates. Thus, the frequency of detection of MRSA was 50%. WebAug 1, 2004 · The two oxacillin disk methods with Mueller-Hinton agar incubated at 30°C, and with Mueller-Hinton agar supplemented with NaCl 4% w/v incubated at 37°C, agreed with each other, but falsely identified 11 isolates as oxacillin-susceptible (sensitivity 90.4%) and three isolates as oxacillin-resistant (specificity 99.1%) in comparison with PCR.
