• verotoxin 1-producing Escherichia coli
• vt1c gene

A total of 232 verotoxin 1 (VT1)-positive, VT-producing Eschericha coli (VTEC) strains isolated from goats, sheep, and cattle were analyzed for the presence of the vile gene by polymerase chain reaction. One hundred and forty of the 144 (97.2%) caprine strains and 55 of the 63 (87.3%) ovine strains possessed the vac gene. In contrast, the gene was not detected in any of the 25 bovine strains. These results show that the vac gene is round in caprine VTEC strains and confirm that gene is associated with ovine VTEC strains.
