METHODS. A MRSA isolate was routinely isolated from a deep wound specimen, which was positive for PBP2a by lateral flow assay but negative for cefoxitin screen test and susceptible to oxacillin (MIC of 0.5 ug/ml) by VITEK 2 AST-GP75 card. It was also susceptible to cefoxitin using disk ...
Ninety-five of 100 confirmed oxacillin resistant by both, 3 of 5 were oxacillin susceptible by both and mecA negative, and 2 of 5 were oxacillin susceptible by OXA-plate, resistant by FOX-disk and mecA positive. The FOX-disk out-performed the OXA-plate for ORSA confirmation and can be ...
Positive direct Coombs test without haemolysis was found in a frequency similar to that found with the cephalosporins. Clinical superinfections caused by cefoxitin-resistant microorganisms, mainly Pseudomonas, Enterobacter and fungi, were observed to the same extent as can be expected with other broad ...
1.[Methods] PCR amplification of the mecA gene, disk diffusion method with Cefoxitin and Oxacillin testing by Kirby-Bauer method, Screen latex agglutination test were performed to analyze 70 clinical isolates of Staphylococcus.目的以PCR法检测葡萄球菌的mecA基因为金标准,比较头孢西丁纸片扩散法、苯唑西林...
