Mannitol salt agar was evaluated for detection of oxacillin resistance in 136 Staphylococcus aureus isolates. All mecA-positive isolates (n = 54) were correctly categorized as oxacillin resistant by the disk diffusion test (1-microgram disk; zone diameter, < 16 mm); the specificity was 97.6%. Agar screening (2 micrograms of oxacillin per ml) revealed a sensitivity of 98.1% and a specificity of 95.1%.
对136株金黄色葡萄球菌分离株进行了甘露醇盐琼脂检测耐苯唑西林情况的评估。所有mecA阳性分离株(n = 54)通过纸片扩散法(1微克纸片;抑菌圈直径,< 16毫米)均被正确归类为耐苯唑西林;特异性为97.6%。琼脂筛选法(每毫升含2微克苯唑西林)显示敏感性为98.1%,特异性为95.1%。
