Campylobacter jejuni antibodies in Nigerian children.

Abstract

Titers of complement-fixing (CF) antibody to Campylobacter jejuni were demonstrated in 87 (36.7%) of 237 infants 6 to 15 months old in Jos, Nigeria. Of the total number of children examined, 81 had acute diarrhea and 27 of them (33.3%) were found to have CF antibodies in their serum. The remaining 156 children were asymptomatic, and 60 (38.4%) of them had CF antibodies. In the diarrheal group, 27 of 75 children 6 to 8 months old were CF antibody positive. There was no significant difference in the incidence of CF C. jejuni antibodies in the diarrheal and nondiarrheal infants (P greater than 0.05). Also, infants 9 to 15 months old had a higher incidence of CF antibodies (46.5%) than those 6 to 8 months of age (25%). The data suggest that the infants whose sera were CF antibody positive had had an exposure to C. jejuni. All 33 infants 6 to 8 months of age who had no diarrhea were CF antibody negative.
