Résumé:

A monoclonal antibody (MAb) was obtained from a mouse immunized with solubilized outer membrane proteins extracted from a bovine enterohemorrhagic strain of Escherichia coli (EHEC), O26. The MAb produced a strong immunoblot reaction at approximately 21 kDa for an O26 strain containing the intimin gene (eae) and verocytotoxin (VT), but not with an O26 eae- and VT-negative strain, or O157 eae- and VT-positive strains. The MAb was used in a sandwich enzyme-linked immunosorbent assay (ELISA) format to screen strains from animal and human sources, and all reactive strains were characterized for …
