摘要 目的分析我院阴沟肠杆菌对临床常用抗菌药物的耐药情况。方法收集我院2003年1月至2005年1月分离菌2116株,革兰阴性菌1225株,占分离菌的57.9%,其中阴沟肠杆菌233株,占分离菌的19.02%。用MicroScanWorkaway40全自动细菌鉴定/药敏分析仪测定20种抗菌药物对细菌的最低抑菌浓度(MIC),按照美国临床实验室标准化委员会(NCCLs)1999年版标准,应用WHONET5.1分析软件,计算MIC50和MIC90,判断敏感率(S%),中介率(I%),耐药率(R%)。结果阴沟肠杆菌对广谱头孢菌素和喹诺酮类抗菌药物耐药率均大于80%,对含酶抑制剂的哌拉西林/他唑巴坦耐药率为45.7%,对阿米卡星耐药率为33.7%。仅对亚胺培南敏感(94.3%)。结论我院分离的阴沟肠杆菌耐药情况严重,临床应引起重视,严格按照抗生素使用原则,合理使用抗生素。
