Abstract

Oxacillin-susceptible, mecA-positive Staphylococcus aureus isolates create a treatment challenge for the clinician. In this article, we describe two cases of bacteremia from isolates that carried the mecA gene but were susceptible to oxacillin (oxacillin-susceptible methicillin-resistant S. aureus [OS-MRSA]). DNA microarray analysis was used to characterize these isolates as a mecA-positive, clonal complex 5, pediatric strain and a mecA-positive, clonal complex 8, USA300 strain.

摘要

耐苯唑西林、mecA 阳性金黄色葡萄球菌分离株给临床医生带来了治疗挑战。在本文中,我们描述了两例由携带 mecA 基因但对苯唑西林敏感(耐苯唑西林、耐甲氧西林金黄色葡萄球菌 [OS-MRSA])的分离株引起的菌血症。DNA 微阵列分析将这些分离株鉴定为 mecA 阳性、克隆复合体 5、儿科株和 mecA 阳性、克隆复合体 8、USA300 株。
