Objectives:
The most common uropathogenic Gram negative bacteria are Escherichia coli and Klebsiella pneumoniae. The purpose of this study was to determine the three most frequent bacterial agents causing Urinary Tract Infections (UTI) in patients who referred to Central Laboratory of Dr. Shariati Hospital, during 2 years (January 2006- December 2007).
Materials And Methods:
The registered data were checked and collected by the questionnaires as a retrospective epidemiological survey. Then, the Chi Square tests were performed by SPSS software.
Outcomes:
The results of the present survey revealed that, the first two bacterial agents in different seasons were similar through the surveillance while the third one was variable. The first two frequent bacteria were respectively, Escherichia coli and Klebsiella pneumoniae.
Conclusion:
The gram negative bacteria of Escherichia coli and Klebsiella pneumoniae were the most common uropathogenic bacteria causing UTI. According to the statistical calculations, there was significant association between UTI caused by Escherichia coli and female gender (p<0.05).
