Abstract

" Purpose: Infections of the urinary tract are common allover the world and occur in all ages and both sex. The organism most commonly isolated from all types of urinary tract infections is Escherichia coli. Materials and Methods: We analyzed E. coli from a woman with acute cystitis. Among the pathogenic determinants of the uropathogenic E. coli strains, the p-fimbriae have been known to be associated with upper urinary tract infections. Results: Type 1 fimbriae (fimH), P family fimbriae (papA), S family fimbriae (sfa), hemolysin (hylA) and cytotoxic necrotizing factor I (cnfI) contribute to virulence in the urinary tract. So, it is important to characterize E. coli in laboratory study. Conclusions: The authors have used tools to reveal characteristics of E. coli, such as polymerase chain reaction, hemagglutination, hemolysin assay. This study provides how to characterize E. coli strains."
