Distribution and drug resistance of Escherichia coli causing urinary tract infections

Objective To approach antimicrobial resistance of E.coli causing urinary tract infections and provide experimental evidence for clinically reasonable choice of antibiotics.Methods 348 pathogen strains in urinary infection isolated from inpatients and outpatients were cultured and identified by ATB and K-B method was performed for drug sensitivity test.Results The antimicrobial resistance of ECO varied from commonly used antibiotics.E.coli was sensitive to carbapenems such as imipenem and meropenem.The resistance rate to ampicillin,cefazolin,Cefuroxime and piperacillin were the highest.Those of ciprofloxacin and levofloxacin were higher than 65.0%.Conclusion E.coli is the most common pathogens of the urinary tract infection,whose resistance is raised.Clinician should pay attention to the changes in drug-resistance of E.coli and prescribe the antibiotic correctly.
