Abstract:
Objective:To study the resistance and its tendency of E.coli to antibiotics was to serve the rational administration in clinic.Methods:WHONET5 was employed to analyze the drug sensitivities of 616 E.coli isolated from the clinical specimens from January,2004 to July,2006 in hospital.Results:The resistance rates of E.coli to Ampicillin,Piperacillin,Amoxicillin/cla,Trimethoprim/Sulfamethoxazole and Ciprofloxacin exceeded 60%,and they were about 50% to Gentamicin,Cefazolin and Cefuroxime.In addition,the resistant rates were20% infra to Piperacillin/tazobactam,Cefepime,Ceftazidime,Cefoxitin,Amikacin and Furantoin,and there was no resistance to Imipenem.The detection rates of ESBLs to E.coli was 27.96%,32.68%,35.12% in 2004,2005,2006 respectively.Conclusions:The resistance rates of E.coli to Penicillins,Piperacillins/Clavulanic acid,Sulfanilamide,Quinolone,Gentamicin,the first and second generations Cephalosporins were high,and they were not suitable for clinical use.To Piperacillins/tazobactam,fourth generation Cephalosporins,Cephamycins,Imipenem,Amikacin and Furantoin,the resistance rates were relatively low,and they could be used clinically.The third generation Cephalosporins should be used cautiously due to its feasibility of inducing ESBLs even though its resistant rates were low.The production rate of ESBLs of E.coli ascended year by year.
