Abstract

We evaluate the performance of BD Phoenix (BD Diagnostic; Hunt Valley, MD) and MiscroScan WalkAway (Beckman Coulter Inc; Carlsbad, CA) systems versus reference agar dilution method for fosfomycin susceptibility determination in 200 Staphylococcus aureus clinical isolates. Both methods exhibit ≤89.0% of categorica agreement and ≥63.3% of very major error. All commercial antimicrobial susceptibility systems show poor concordance with reference method.

摘要

我们评估了 BD Phoenix（BD Diagnostic；马里兰州亨特谷）和 MiscroScan WalkAway（贝克曼库尔特公司；加利福尼亚州卡尔斯巴德）系统在 200 株金黄色葡萄球菌临床分离株中检测磷霉素药敏性与参考琼脂稀释法的性能。两种方法的分类一致性均≤89.0%，且严重错误率均≥63.3%。所有商业抗菌药物敏感性系统与参考方法的一致性均较差。
