目的研究住院患者泌尿道感染病原体分布状况及其耐药性特点,为制定有效防控措施提供依据。方法采用分离培养和生化鉴定技术,对某医院泌尿系感染患者标本进行菌株分离培养、菌种鉴定和耐药性评价。结果该医院在2010-2011年共3 779例标本中检出病原菌2 098株。所检出的病原菌中,革兰阴性杆菌占44.3%,以大肠埃希菌感染为主;真菌占34.8%,以热带假丝酵母菌为主。大肠埃希菌和克雷伯菌对临床常用抗菌药物普遍耐药。结论住院患者泌尿道感染病原菌以革兰阴性杆菌和真菌为主,大肠埃希菌为主要病原菌,且普遍耐药。
Objective To study the distribution of urinary tract infection in hospitalized patients and the characteristics of its drug resistance, so as to provide basis for effective prevention and control measures. Methods Isolation and biochemical identification techniques were used to isolate, culture and identify strains of bacteria in patients with urinary tract infection in a hospital. Results The hospital detected 2098 strains of pathogens in 3 779 specimens from 2010 to 2011. Of the pathogens detected, gram-negative bacilli accounted for 44.3%, with Escherichia coli infection as the main fungi accounted for 34.8%, mainly Candida tropicalis. Escherichia coli and Klebsiella commonly used in clinical antibacterials generally resistant. Conclusions In-patients urinary tract infections are mainly Gram-negative bacilli and fungi, Escherichia coli is the main pathogen and generally resistant.
