Production of a monoclonal antibody specific for the major outer membrane protein of Campylobacter jejuni and characterization of the epitope.

ABSTRACT: Campylobacter species are important enteric pathogens causing disease in humans and animals. There is a lack of a good immunological test that can be used routinely to separate Campylobacter jejuni from other Campylobacter species. We produced monoclonal antibodies (MAbs) directed against the major outer membrane protein (MOMP) of C. jejuni using recombinant MOMP as the antigen. One MAb, designated MAb5C4 and of the immunoglobulin G1 isotype, was found to be potentially specific for C. jejuni. Dot blots demonstrated that MAb5C4 reacted with all 29 isolates of C. jejuni tested but did not react with 2 C. jejuni isolates, 26 other Campylobacter spp. isolates, and 19 non-Campylobacter isolates. Western blotting showed that MAb5C4 bound to a single protein band approximately 43 kDa in size, co
