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.
