Samples of serum from 187 homosexual and 169 heterosexual men were examined by means of an indirect immunofluorescent antibody test for the presence of antibody reactive with Campylobacter jejuni. Antibody of the IgG class was detected in the serum of 19 (10.2 per cent) and 15 (8.9 per cent) homo- and heterosexual men respectively. The prevalence of serum antibody in men attending a sexually transmitted diseases clinic was higher than in a previously reported control group.
