We previously demonstrated that the rinderpest virus (RPV) hemagglutinin (H) protein plays an important role in determining host range but that other viral proteins are clearly required for full RPV pathogenicity to be manifest in different species. To examine the effects of the RPV nucleocapsid (N) protein and phosphoprotein (P) genes on RPV cross-species pathogenicity, we constructed two new recombinant viruses in which the H and P or the H, N, and P genes of the cattle-derived RPV RBOK vaccine were replaced with those from the rabbit-adapted RPV-Lv strain, which is highly pathogenic in rabbits. The viruses rescued were designated recombinant RPV-lapPH (rRPV-lapPH) and rRPV-lapNPH, respectively. Rabbits inoculated with RPV-Lv become feverish and show leukopenia and a decrease in body weight gain, while clinical signs of infection are never observed in rabbits inoculated with RPV-RBOK or with rRPV-lapH. However, rabbits inoculated with either rRPV-lapPH or rRPV-lapNPH became pyrexic and showed leukopenia. Further, histopathological lesions and high virus titers were clearly observed in the lymphoid tissues from animals infected with rRPV-lapPH or rRPV-lapNPH, although they were not observed in rabbits infected with RPV-RBOK or rRPV-lapH. The clinical, virological, and histopathological signs in rabbits infected with the two new recombinant viruses did not differ significantly; therefore, the RPV P gene was considered to be a key determinant of cross-species pathogenicity.
