Distribution and drug resistance of pathogens causing urinary tract infections in 2010

OBJECTIVE To analyze the distribution and drug resistance of the pathogens causing urinary tract infections so as to guide the clinical reasonable use of antibiotics.METHODS A total of 308 strains of pathogens from patients with urinary tract infections were collected from Jan 2011 to Dec 2011 and cultivated.Antibiotic susceptibility testing was performed by Kirby-Bauer method.RESULTS The gram-negative bacilli were the predominant pathogens causing urinary tract infections,accounting for 53.0%,there were 86(27.9%) strains of gram-positive cocci;among all the pathogens isolated,Escherichia coli,Enterococcus faecalis,and Klebsiella pneumoniae were the top three species,accounting for 42.5%,17.2%,and 8.1%,respectively,the fungal infections decreased in a certain extent,accounting for 9.1%;part of the pathogens were multidrug-resistant.CONCLUSION The gram-negative bacilli remain the predominant pathogens causing urinary tract infections,it is of great significance in the reasonable use of antibiotics and infection control to analyze the distribution and drug resistance of the clinically isolated pathogens.
