A reverse-sandwich enzyme-linked immunosorbent assay (ELISA), in
which an antibody is sandwiched by antigens, was established for the
titration of antibodies to verocytotoxins (VT) in human and animal
sera. This assay has two advantages over a conventional indirect ELISA:
(i) higher specificity and sensitivity and (ii) the ability to
comparably titrate antibodies from different species. The VT1
(Shiga-like toxin 1) antibody-positive rates were 5% in 202 normal
adult humans and 99% in 93 normal cattle at a dairy farm. This ELISA
is most suitable for seroepidemiologic studies of infections with
VT-producing Escherichia coli in humans and various animal species.
