摘要
目的了解尿路感染患者病原菌分布及其耐药性特征,为临床合理用药提供依据。方法对尿路感染患者尿培养分离出的330株病原菌进行细菌鉴定和药物敏感试验,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,占62.4%,革兰阳性球菌为23.9%,真菌为13.7%;产ESBLs大肠埃希菌的检出率为40.8%,产ESBLs肺炎克雷伯菌的检出率为15.4%。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具有重要意义。
Objective To explore the distribution of pathogens in patients with urinary tract infection and the drug resistance of the pathogens. Methods 330 strains of pathogens were identified and drug resistance was conducted. ESBLs examinations of gram negative bacilli were made. Results Of all the pathogens, gram negative bacilli accounted for 62.4% ,gram positive bacilli 23.9% and fungi 13.7%. The detection rates of Escherichial eoli and Kpneumoniae were 40.8% and 15.4% respectively. Conclusion Gram negative bacilli are the main pathogens of urinary tract infection and the drug resistance tends to rise, which indicates that it is important to conduct the monitoring of pathogens and drug resistance analysis.
