title: [Construction and immunogenicity of recombinant adenoviruses expressing Cap protein of PCV2 and GP5 protein of PRRSV in mice].
abstract: Porcine circovirus 2 (PCV2) has been implicated as the etiological agent of postweaning multisystemic wasting syndrome (PMWS). Co-infection of PCV2 and porcine reproductive and respiratory syndrome virus (PRRSV) can result in severe economic losses to the swine industry. In this study, we constructed the recombinant adenovirus rAd-Cap-GP5 expressing Cap of PCV2 and GP5 of PRRSV. And the expression of Cap and GP5 protein in the HEK-293 cells inoculated with rAd-Cap-GP5 were confirmed by immunoperoxidase monolayer assay (IPMA), indirect immunofluorescence assay (IFA) and Western blotting, respectively. The immunogenicity of recombinant adenoviruses rAd-Cap-GP5 was examined in mice by vaccination with the recombinant adenovirus. The results showed that the mice could produce anti-PCV2 and PRRSV antibodies detected by indirect ELISA and virus neutralization assay. It indicated that rAd-Cap-GP5 could provide humoral immunity responses in mice. The recombinant adenovirus rAd-Cap-GP5 might be an attractive candidate vaccine for preventing the disease associated with PCV2 and PRRSV infection.
