Résumé :

[BDSP. Notice produite par INIST-CNRS e8NQR0xn. Diffusion soumise à autorisation]. Faecal samples from 3268 randomly selected inhabitants of two provinces in the northern region of Iran were screened to detect Verotoxin-producing Escherichia coli (VTEC) using colony sweep polymyxin-B extraction method. Non-sorbitol fermentation phenotype and slide agglutination with 0157 and H7 antisera used to detect this serotype. We found that 0.7% of the population were infected with VTEC, however none of the isolates belonged to O157 : H7 serotype. We also found that children<6 years of age were at highest risk of infection with VTEC (p<0.05). Moreover, a significant association was found between the VTEC and diarrhoeal cases at the same age group (p<0.001). Overall distribution of the VTEC isolates in the general population was found to be random, though a kind of clustered distribution could be noticed.
