Distribution and Drug Sensitivity of Pathogenic Bacteria among 1513 Cases with Urinary Tract Infection / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To understand the distribution and the drug resistance of the pathogenic bacteria so as to guide rational application of antibiotics for clinics.METHODS Bacteria culture and drug sensitivity with urine specimen were done among 1513 cases with urinary tract infection.RESULTS Urinary infection was mostly due to Gram-negative bacilli.Gram-positive cocci and fungi were the second.The top four pathogens were Escherichia coli(47.5%),Enterococcus faecium(8.7%),Candida albicans(7.0%),and Klebsiella pneumoniae(6.5%).The positive rates of urinary smear and culture were 51.9% and 29.3%,respectively with a coincidence rate of 77.4%.The drug resistance rates against imipenem,vancomycin and linezolid were zero,with 19.3% and 34.5% against extended-spectrum ?-lactamases-producing E.coli(ESBLs) and K.pneumoniae together,with 33.3% and 58.2% against meticillin-resistant coagulase negative Staphylococcus(MRCNS) and high-level gentamicin resistance(HLGR).CONCLUSIONS Urinary smear,bacteria culture and drug sensitivity tests can offer the basis for clinical rational use of antibiotics.
