摘要

A total of 232 verotoxin 1 (VT1)-positive, VT-producing Escherichia coli (VTEC) strains isolated from goats, sheep, and cattle were analyzed for the presence of the vt1c 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 vt1c gene. In contrast, the gene was not detected in any of the 25 bovine strains. These results show that the vt1c gene is found in caprine VTEC strains and confirm that gene is associated with ovine VTEC strains.
