摘要 目的 了解新华医院 3年血培养中分离菌株的构成比及耐药情况。方法 患者血培养标本经Bact/AlertTM血培养仪培养 ,分离所得菌株用Vitek 32全自动微生物分析 /药敏系统进行鉴定和药敏试验。结果 在46 5株菌株中 ,革兰阳性菌占 5 8.7%,革兰阴性菌占 38.1%,念珠菌属占 3.2 %。革兰阳性菌前 3位依次是凝固酶阴性葡萄球菌、金黄色葡萄球菌和粪肠球菌。耐甲氧西林的金黄色葡萄球菌 (MRSA)占金黄色葡萄球菌的6 4.7%,耐甲氧西林的凝固酶阴性葡萄球菌 (MRCoNS)占凝固酶阴性葡萄球菌的 90 .2 %,无万古霉素耐药株。粪肠球菌对高浓度的庆大霉素和高浓度的链霉素的耐药率分别为 6 1.5 %和 46 .2 %。革兰阴性菌前 3位依次是大肠埃希菌、肺炎克雷伯菌和铜绿假单胞菌。大肠埃希菌和肺炎克雷伯菌的产超广谱 β 内酰胺酶 (ESBLs)菌株分别占 2 8.6 %和 34 .6 %。铜绿假单胞菌对亚胺培南的耐药率为 12 .5 %。结论 对血培养中分离菌株进行耐药性监测很有必要 ,可以指导临床合理使用抗生素 ,同时为制定经验治疗方案提供依据。
