In this study sorbitol MacConkey agar was used to screen
E. coli isolated from 894 children with diarrhoea. Thirtyfour non-sorbitol fermenters were detected. On serotyping, three organisms
belonged to the 0157 serogroup. Only one of these possessed the H7 antigen. This organism was a verotoxin producer. These
findings suggest that
E. coli 0157:H7 is an uncommon enteric pathogen in Irish children.
