Abstract
Safe and efficient vaccination is important for rabies prevention in domestic animals. Replicative vectors expressing the rabies virus glycoprotein, derived from canine adenovirus have been reported to be promising vaccines in various animal models. In this paper we compare the potential of a replicative and a non-replicative vector, both based on canine adenovirus type 2 and expressing the rabies glycoprotein. Upon inoculation in sheep, immune responses against the rabies virus protein elicited by recombinant vectors were monitored. All immunised sheep produced a rapid and potent neutralizing antibody response against rabies virus after a single inoculation of either replicative or non-replicative recombinant canine adenovirus type 2. In addition, the non-replicative vector expressing the rabies glycoprotein stimulated antigen-specific CD4+ and CD8+ lymphocyte proliferation as well as IFN-γ production. These results suggest that vectors derived from canine adenovirus 2 could be considered for the development of promising vaccines in the ruminant species.
