Abstract:
OBJECTIVE To investigate the drug-resistance of ESBLs-producing Escherichia coli for guiding the clinical drug-using.METHODS The Kirby-Bauer agar diffusion method was used to analyze the drug resistance of 68 E.coli isolates in these three years.The ESBLs-producing strains were detected by confirmed test.RESULTS Thirty one ESBLs-producing strains were detected and the isolated rate was 54.4%;the resistant rates of these isolates were up to 50% to penicillin and three generations cephalosporin.The resistant rate to quinolone was about 70%.All of the strains were susceptible to imipenem.CONCLUSIONS More attention should be paid on the detection of ESBLs-producing E.coli and prevent the prevalence of the drug-resistant strains.
