Abstract:
OBJECTIVE To analyze the drug-resistance of Enterobacter cloacae isolated from clinic in the past two years.METHODS The drug-resistance by K-B method,and to perform 3-D test to detect AmpC ?-lactamase and ESBLs were detected.RESULTS One hundred and six strains of E.cloacae was detected.Burn department were the wards which had the highest detection rate.Sputum,wound,bile and drainage fluid had the highest positive rate.Sensitivity test results showed that the resistance rate to penicilins,Ⅰ,Ⅱ-generation cephalosporins and cefoxitin of E.cloacae was the highest,and the resistance rate to the third,and fourth-generation cephalosporins was 24.5-50.9%.The detection rate of ESBLs and AmpC was 27.4% and 40.6%,respectively.Twenty three strains produced both of them.CONCLUSIONS The detection rate and drug resistance of E.cloacae are increasing severely.Laboratory should pay more attention to their detections and surveillance so as to control hospital infection of E.cloacae.
