OBJECTIVE To investigate the drug resistance of ESBLs-producing Escherichia coli in community-acquired urinary tract infection for guiding the clinical drug-using.METHODS ATB-Expression analysis system was used for identification of bacteria,extra-susceptibility tests were detected by K-B method.RESULTS Totally 104 E.coli strains were detected,the isolation rate of ESBLs-producing E.coli was 13.5%,the resistant rates of E.coli were up to 70% to ampicillin,piperacillin and Co-trimoxazole,the resistant rate was up to 55% to ciprofloxacin and levofloxacin,and the susceptible rate was 100% to imipenem.CONCLUSIONS The E.coli is a main pathogen in community-acquired urinary tract infection,Its drug resistance is extremely severe.To enhance detecting drug resistance of pathogenic bacteria is of important significance for guiding the clinical rational drug-using and reducing drug-resistant strains.
