Résumé
Background and Objectives: Shiga toxins [verotoxin] is one of the most important bacterial toxin produced by the Escherichia coli [O157: H7 and nonO157: H7], and is responsible for various diseases in humans and animals. Hemolytic uremic syndrome [HUS] is serious human diseases that occur because of these toxins. There is no comprehensive information in this regard, here will studied the prevalence of these genes among the E- coli isolated from urine samples in Khorramabad
Material and Method: The study is based on 146 Escherichia coli isolates of Patients with symptoms of urinary tract infection referred to clinical laboratories in Khorramabad during 90-1389. We used we identified the isolates by biochemical tests .The Multiplex PCR Multiplex PCR method were used to presence of genes
Results: A total of 117 [13/80%] of the women and 29 [86/19] of the men and none of them carried both stx1and stx2
Conclusion: Shiga toxin-producing E. coli isn't responsible for urinary tract infection in KhorramabadAlthough the frequency of these genes in urine samples is low, but evaluation of the other human and animal samples in different parts of the country is essential
