Subtilase cytotoxin-encoding subAB2 variants in verotoxin-producing Escherichia coli strains isolated from goats and sheep
文摘

subAB2 variants were investigated in caprine and ovine subAB2-positive VTEC strains.

About 60% of the caprine and ovine strains possessed the subAB2-1 variant.

All caprine and ovine strains, except one, were positive for the subAB2-2 variant.

Occurrence of both variants is not associated with higher risk of disease in humans.
