Identification of an antigen common to different species of the genus Campylobacter

Abstract

Affinity-purified antibody specific for a determinant on flagellin from Campylobacter jejuni was used to screen by immunoblotting strains of C. coli, C. laridis, C. fetus, 'C. upsaliensis', C. pylori, and C. sputorum biovar fecalis. The antigen was detected in each of these species, but the molecular weights of the proteins bearing the common antigen varied considerably.
