Oral immunization of chickens with avirulent Salmonella vaccine strain carrying C. jejuni 72Dz/92 cjaA gene elicits specific humoral immune response associated with protection against challenge with wild-type Campylobacter.

Abstract excerpt

It is well documented that poultry and poultry products are the major source of human campylobacteriosis and salmonellosis. This study examined the general efficacy of avirulent Salmonella vaccine strains expressing Campylobacter antigen as a bivalent chicken vaccine prototype. Three C. jejuni genes: cjaA (cj0982c), cjaC (cj0734c) and cjaD (cj0113) encoding highly immunogenic proteins which are conserved among...
