Abstract:
OBJECTIVE To investigate the drug resistance of Escherichia coli in biliary tract infection and genotype of ESBLs.METHODS Antimicrobial susceptibility test was performed using Kirby-Bauer method.The genotypes of ESBLs were detected by PCR.RESULTS The detection rate of ESBLs producing bacteria was 32.4%(23 strains),and the drug-sensitivity test indicated that E.coli was sensitive to imipenem,meropenem and cefoperazone/subactam,but these ESBLs producing strains were resistant to other antimicrobial agents.ESBLs were identified as TEM type in 16 strains,SHV type in 4 strains,CTX-M type in 12 strains and OXA type in 5 strains.CONCLUSIONS ESBLs-producing E.coli in biliary tract infections show strous resistance.TEM and CTX-M are the most common ESBLs genotypes.
