摘 要: | 目的调查医院大肠埃希菌感染的临床分布、耐药性及患者感染产ESBLs菌的危险因素,为临床合理使用抗菌药物提供科学依据。方法采用法国生物梅里埃公司ATB细菌鉴定仪对ESBLs菌进行检测,药敏试验用K-B纸片法,根据2005年美国NCCLS标准判断结果,应用WHONET5软件对临床分离细菌的药敏结果进行数据统计分析。结果确证87株产ESBLs,产酶率为31.5%;276株大肠埃希菌中尿液分离出35株(40.2%),痰液23株(26.4%),血液7株(8.0%);各病区产ESBLs菌的分离率以ICU最高(36.8%),其次为烧伤病房(16.1%),泌尿外科病房(14.9%);产ESBLs大肠埃希菌的耐药率显著高于非产ESBLs大肠埃希菌;感染产ESBLs菌危险因素为长期使用三代头孢菌素、入住ICU患者。结论我院大肠埃希菌产ESBLs菌以SHV型为主:产ESBLs菌尚未有效控制,仍然处于较高水平;治疗大肠埃希菌感染时,需根据药敏结果及患者病情选用碳青酶烯类、氨基糖苷类、β内酰胺类抗生素/β内酰胺酶抑制剂等。

Abstract: | Objective To investigate the clinical distribution of the infection by E.coli and the antimicrobial resistance and the risk factor for infection,so as to provide scientific basis for reasonable clinical use of antibiotics.Methods To detect ESBLs by ATB microbiological system,We used Rirby-Bauer(K-B) test for antibiotics susceptibility test and The results were evaluated based on National Committee for clinical Laboratory Standards(NCCLS)of the USA in 2005.The data were analyzed by using WHONET-5 software.Re... |
