Drug Resistance of Pathogens Isolated from Urinary Tract / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To approach the distribution characteristic and drug resistance status in pathogens from infected urinary tract in Jingshan County and offer the scientific evidence for clinically reasonable use of antibiotics.METHODS Totally 218 strains of pathogens isolated from urinary tract were identified by routine methods according to the National Clinical Laboratory Operation Rules.Drug susceptibility testing was performed by K-B methods recommended by CLSI.RESULTS Among 218 strains of pathogens from infected urinary tract,Escherichia coli accounted for 61.0%,ranking the first and enterococci ranked the second,accounted for 11.5%.Except for 100% sensitivity to vancomycin and teicoplanin in Gram-positive bacteria and to imipenem and meropenem in Gram-negative bacteria,the pathogens from infected urinary tract had been resistant to commonly used antibiotics in some degrees.The detection rate of extended-spectrum beta-lactamases(ESBLs) producers was 32.9%.CONCLUSIONS The drug resistance in pathogens from infected urinary tract is on the rise.We should strengthen monitoring and controlling of it.
