The Xpert MRSA/SA Blood Culture (BC) assay (Cepheid, Sunnyvale, CA) was prospectively compared to culture and found to have excellent specificity for both Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) in BC specimens with a sensitivity of 75% (3/4) and 100% (17/17), respectively. Among 28 heterogeneous vancomycin-intermediate S. aureus (hVISA)/VISA spiked BCs, the assay correctly identified 84.6% VISA and 80% hVISA isolates as MRSA.
Xpert MRSA/SA 血培养 (BC) 检测试剂盒（Cepheid，加利福尼亚州森尼韦尔）前瞻性地与培养法进行了比较，结果表明，该检测试剂盒对 BC 标本中的金黄色葡萄球菌和耐甲氧西林金黄色葡萄球菌 (MRSA) 具有优异的特异性，其敏感性分别为 75%（3/4）和 100%（17/17）。在 28 份异质性万古霉素中介金黄色葡萄球菌 (hVISA)/万古霉素耐药金黄色葡萄球菌 (VISA) 污染的 BC 中，该检测试剂盒正确地将 84.6%的 VISA 和 80%的 hVISA 分离株鉴定为 MRSA。
