摘要 目的:分析大肠埃希菌(ECO)及肺炎克雷伯菌(KPN)耐药性变化趋势,以及产超广谱β-内酰胺酶(ES-BLs)和非产ESBLs菌株的药敏差异,为指导临床用药提供依据。方法:用美国临床实验室标准化委员会(NCCLS)推荐的初筛试验和表型确证试验检测ESBLs产生株,使用最低抑菌浓度法和K-B法检测临床分离的大肠埃希菌和肺炎克雷伯菌1178株对10种抗菌药物的耐药性情况。结果:我院近5年来,大肠埃希菌和肺炎克雷伯菌中ESBLs检出率分别为27.8%和16.15%,总检出率23.9%,产ESBLs菌株对10种抗菌药物的耐药率比不产酶菌株均有不同程度的增加,但所有菌株对亚胺培南都敏感。结论:产ESBLs菌株在大肠埃希菌和肺炎克雷伯菌中的检出率呈逐年上升趋势,产ESBLs菌株对所测试的10种抗菌药物的耐药程度比不产酶株为高,且呈多重耐药性,但所有菌株对亚胺培南均敏感。
