ABSTRACT
The specificity of 97 monoclonal antibodies (MAbs) to the Campylobacter jejuni Lior serogroup 6 reference strain was assessed using an indirect enzyme linked immunosorbent assay (ELISA). Four MAbs, M316, M337, M357 and M637, reacted with whole cells of the C. jejuni, C. coli and C. lari reference strains of the 20 most common Lior serogroups and 25 recent C. jejuni and C. coli isolates, and did not react with most of the 42 other Campylobacter and non-Campylobacter spp. tested. Immunoblot analysis revealed that MAbs M337 and M357 reacted with a protein component with molecular mass of approximately 62 kiloDaltons (kDa) while M316 and M637 reacted with protein components of approximately 92 and 31 kDa, respectively. The detection limit of M357 in an indirect ELISA was 10(5) colony forming units. These four highly specific MAbs may be useful reagents of an immunoassay for the rapid detection of thermophilic campylobacters in foods and clinical samples.
