Pathogens Isolated from Infected Urinary Tract in Suizhou:Strain Distribution and Drug Resistance

OBJECTIVE To investigate the distribution characteristic and drug resistance status in pathogens isolated from infected urinary tract and offer the scientific evidence for reasonable usage of antibiotics.METHODS Totally 257 strains of pathogens isolated from infected urinary tract were identified by auto-microbiological assay and antibiotic susceptibility test was performed by K-B method.RESULTS Among 257 strains,Escherichia coli accounted for 60.3%,ranking the first.Enterococci ranked the second,accounting for 10.5%.Except for 100% sensitivity to imipenem,meropenem,vancomycin and teicoplanin,the pathogens were resistant to the other antibiotics in different degrees.The detection rate of extended-spectrum beta-lactamases(ESBLs) producers in E.coli and Klebsiella pneumoniae were 40.0% and 37.5%,respectively.CONCLUSIONS The drug resistance of pathogens from infected urinary tract is on the rise.We should strengthen monitoring and controlling of it.
