Genotyping of Virulence Factors of Uropathogenic Escherichia coli by PCR

ABSTRACT

Background: Escherichia coli is the most causative agent of urinary tract infections [UTIs]. Apart from all human infectious diseases, UTI have a high prevalence and in most cases, Escherichia coli is a dominance bacterium which can cause pyelonephritis and cystitis. The aim of the study was to determine the occurrence of some virulence genes expressing fimbriae, production of hemolysin and aerobactin among a hundred Escherichia coli isolates obtained from in-and outpatients of Karaj Shahid Rajaii hospital, showing clinical and laboratory signs of UTI.
