摘　　要：目的探讨医院内尿路感染病原菌的分布情况及耐药特征,为临床合理选用抗菌药物提供依据。方法收集2003年1月-2005年12月住院患者发生尿路感染的标本中分离的272株病原菌,进行细菌鉴定和药敏试验,并对革兰阴性杆菌进行ESBLs的检测。结果尿路感染病原菌以革兰阴性杆菌为主(68.4%),革兰阳性球菌为19.1%,真菌为12.5%;产ESBLs大肠埃希菌的检出率为41.1%,产ESBLs肺炎克雷伯菌的检出率为18.2%。结论革兰阴性杆菌是尿路感染的主要病原菌,病原菌的耐药率呈上升趋势;重视病原菌的监测和耐药性分析,对指导临床合理使用抗菌药物,控制医院感染具有重要意义。OBJECTIVE To determine distribution of pathogens and resistance characteristic in urinary infection and to provide basis for clinicians to select antibiotics correctly.METHODS A total of 272 strains of pathogens were identified and ESBLs-producing G-bacilli were detected.RESULTS Among 272 strains,68.4% of G-bacilli,19.1% of G＋cocci,12.5% of fungi,41.1% of Escherichia coli and 18.2% of Klebsiella pneumoniae strains produced ESBLs.CONCLUSIONS G-bacilli are major pathogens of urinary infection and their resistance is raised.Much attention should be paid to resistance detection.It is important to control nosocomial infection and select antibiotics correctly.
