摘要 目的:分析我院血流感染金黄色葡萄球菌(SAU)的临床分布及对常用抗菌药物的耐药性,为预防控制和临床治疗SAU血流感染提供指导。方法:应用WHONET5.4软件对本院2007年1月至2011年12月确诊为SAU血流感染的患者临床资料和菌株的耐药性进行分析,采用SPSS16.0软件进行统计学分析。结果:临床分离的167株SAU广泛分布于全院各科室,分离率最高为ICU占16.17%,其次为儿科病区和心内病区分离率分别为10.78%和10.18%;167株SAU中,70株为耐甲氧西林金黄色葡萄球菌(MRSA),占41.90%;金黄色葡萄球菌对多种抗菌药物呈普遍耐药,对青霉素G的耐药率为99.10%,利福平的耐药率<15.00%,未分离到对利奈唑胺、喹奴普汀/达福普汀、替考拉宁及万古霉素耐药的菌株。对大多数抗菌药物MRSA的耐药率显著高于甲氧西林敏感金黄色葡萄球菌(MSSA)(P<0.01)。结论:血流感染的SAU对常用抗菌药物显示多药耐药,没发现耐万古霉素的MRSA,MRSA耐药性比MSSA严重,医院应大力加强抗菌药物的监控和管理力度,根据药敏合理选用抗菌药物,延缓细菌耐药性的产生并积极做好各项防治措施,防止MRSA的暴发流行。
