Introduction: Escherichia coli O157: H7 are recognized as important aetiological agents of diarrhea in children, particularly in developed countries.

Aim: The aim of the study was to determine the rates of detection of E. coli O157: H7strains among children in Ahvaz, Iran.

Materials and Methods: From June 2010 to December 2010, 137 diarrheal stool samples of children were collected. E.coli was identified by standard microbiological techniques. O157 or O157:H7 subtypes discerned by serological tests.

Results: Of the 137 E. coli isolates, enteropathogens were found in 53 (38.7%) of the patients as follow: Shigella spp. (75.5%), EPEC (enteropathogenic E. coli) (16.9%), Campylobacter spp. (3.8%) and Salmonella spp. (3.8%). None of the isolated E. coli was O157:H7 serotype.

Conclusion: This shows that non-O157:H7 E. coli are the major cause of paediatric infections in this region of Iran.
