	abstract = {We found naturally occurring, potentially virulent Escherichia coli O157:H7 strains in sheep. The incidence of E. coli O157:H7 was transient and ranged from 31\% of sheep in June to none in November. The use of a sensitive culture technique and the choice of the proper sampling season were both essential for detecting this bacterium in sheep. DNA hybridizations showed that 80\% of the E. coli O157:H7 isolates had at least two of the Shiga-like toxin types I or II or the attaching-effacing lesion genes.},
