Polyvalent vaccines against more than one species of pathogens are especially important due to the complex ecosystem in aquaculture. We have previously shown that the development of polyvalent vaccines by shuffling six ompA genes from different bacteria with V. parahaemolyticus VP0764 primers. Here, we used the same 6 genes, V. alginolyticus VA0764 and VA1186, V. parahaemolyticus VP0764 and VP1186, E. tarda ompA and E. coli ompA, but with E. tarda ompA primers to develop new polyvalent vaccines. By this approach, we identified 7 potential polyvalent vaccines that were effective against both V. alginolyticus and E. tarda infections. Furthermore, the innate immunity triggered by the vaccines were also explored in three groups, no protection (group I), protection against V. alginolyticus (group II), and protection against both V. alginolyticus and E. tarda (group III). The transcription of IL-1β, IL-6, IL-8, C3b and NF-kB were significantly increased in group II and group III but not group I, where the expression level of group III was higher than group II. In addition, differential activities of succinate dehydrogenase were detected among the three groups. These results indicate the expansion of polyvalent vaccine reservoir with the same shuffling genes but different primers, and promote the understanding of the mechanisms of polyvalent vaccines based on vaccine-induced innate immunity.
