Distribution and Antibiotic Resistance of Pathogens Causing Urinary Infection among Patients with Urinary Calculus / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To understand the distribution and antibiotic resistance of the pathogens causing urinary infection among the patients with urinary calculus.METHODS Totally 406 strains were isolated from the 1244 urinary specimens.The antibiotic susceptibility of these strains was detected.RESULTS The most of pathogens were G-bacteria(348,85.7%).G+ bacteria and fungi accounted for 12.1%(49/406),and(2.2%,9/406).The most popular pathogens were Escherichia coli(54.9%),Klebsiella pneumoniae(8.1%),Staphylococcus(7.4%),Enterobacter(4.9%),and Enterococcus(3.7%).The detection rate of ESBLs was 52.5%.Meticillin-resistant Staphylococus accounted for 83.3%.Clindamycin-induced resistance of Staphloccocus accounted for 20.0%.6.7% Vancomycin-resistant Enterococcus were isolated.CONCLUSIONS G-bacteria are the most popular pathogens and show increased resistance to common antibiotics.The results of the paper will be usefal for the doctors to choose antibiotics reasonably.
