This invention comprises a recombinant protein comprising the maltose binding protein (MBP) of Escherichia coli fused to amino acids 5-337 of the FlaA flagellin of Campylobacter coli VC167 which has provided evidence of immunogenicity and protective efficacy against challenge by a heterologous strain of campylobacter, Campylobacter jejuni 81-176 in mammals. The invention further comprises a recombinant DNA construct encoding the immunodominant region (region I through III) of flagellin from Campylobacter spp. for use as a component of a vaccine against Campylobacter diarrhea. The invention therefore represents an effective treatment against Campylobacter but avoids inducing the autoimmune Guillain Barre Syndrome (GBS), a post-infection polyneuropathy caused by Campylobacter molecular mimicry of human gangliosides which has hampered the development of vaccines heretofore.
