Sequence of astA gene in Korean and Japanese E. coli isolates was compared. All astA-positive E. coli isolates were negative for other virulence factors. Bovine, porcine, and healthy human carrier isolates carried the identical astA. Polymorphisms of multiple clonal astA in E. coli outbreak isolates were found.
