Abstract:
OBJECTIVE To investigate the infection and drug-resistance of Escherichia coli.METHODS Double disk diffusion test and improved three-dimensional test were adopted to test ESBLs and AmpC of 135 E.coli strains obtained from bile cultivation from operations of biliary inpatients in our hospital from 2003 to 2005,and King-Bauer′s was used to test the sensitivity of 14 kinds of common antibiotics.RESULTS The detection rate of ESBLs producing bacteria was 30.4%(41 strains),and that of AmpC producing bacteria was 5.2%(7 strains);drug-sensitivity test indicated,that E.coli was sensitive to meropenem,imipenem,cefoperazone / subactam,ciprofloxacin and amikacin.CONCLUSIONS E.coli is a main bacterium in biliary infection,and the strains producing ESBLs and /or AmpC are resistant to the cephalosporins of third and fourth generation;prematurely and excessively using broad-spectrum antibiotics before operation is the primary cause to increase in enzyme-producing strains.
