Poultry are considered the major reservoir for Campylobacter
jejuni, a leading bacterial cause of human food-borne diarrhea. To understand the ecology of C. jejuni and develop
strategies to control C. jejuni infection in the animal
reservoir, we initiated studies to examine the potential role of
anti-Campylobacter maternal antibodies in protecting young
broiler chickens from infection by C. jejuni. Using an
enzyme-linked immunosorbent assay (ELISA), the prevalence of
anti-C. jejuni antibodies in breeder chickens, egg yolks,
and broilers from multiple flocks of different farms were examined.
High levels of antibodies to the organism were detected in serum
samples of breeder chickens and in egg yolk contents. To determine the
dynamics of anti-Campylobacter maternal antibody
transferred from yolks to hatchlings, serum samples collected from five
broiler flocks at weekly intervals from 1 to 28 or 42 days of age were
also examined by ELISA. Sera from the 1-day and 7-day-old chicks showed
high titers of antibodies to C. jejuni. Thereafter,
antibody titers decreased substantially and were not detected during
the third and fourth weeks of age. The disappearance of
anti-Campylobacter maternal antibodies during 3 to 4 weeks of age coincides with the appearance of C. jejuni
infections observed in many broiler chicken flocks. As shown by
immunoblotting, the maternally derived antibodies recognized multiple
membrane proteins of C. jejuni ranging from 19 to 107 kDa.
Moreover, in vitro serum bactericidal assays showed that
anti-Campylobacter maternal antibodies were active in
antibody-dependent complement-mediated killing of C. jejuni. Together, these results highlight the widespread presence
of functional anti-Campylobacter antibodies in the poultry production system and provide a strong rationale for further
investigation of the potential role of anti-C. jejuni
maternal antibodies in protecting young chickens from infection by
C. jejuni.
