  • Title: Vaccination against Newcastle disease with a recombinant baculovirus hemagglutinin-neuraminidase subunit vaccine.
    Author: Nagy E, Krell PJ, Dulac GC, Derbyshire JB.
    Journal: Avian Dis; 1991; 35(3):585-90. PubMed ID: 1953580.
    Abstract:
    Vaccination of chickens with an oil-emulsion vaccine containing a recombinant baculovirus that expressed the hemagglutinin-neuraminidase (HN) of Newcastle disease virus (NDV)-induced hemagglutination-inhibition (HI) and virus-neutralizing antibodies against NDV. HI antibody titers obtained in response to vaccination with the live recombinant virus were higher than those obtained when the recombinant was inactivated with beta-propiolactone, and the titers were lower than those obtained in response to the same HN concentrations in live or beta-propiolactone-inactivated NDV strain B1. The serological response to the recombinant baculovirus was differentiated from the response to NDV by an enzyme-linked immunosorbent assay in which purified NDV nucleoprotein was used as antigen. Chickens vaccinated with the live recombinant or with inactivated NDV resisted an oculonasal challenge with the neurotropic velogenic Texas GB strain of NDV, which was lethal in unvaccinated controls. It was concluded that the HN protein of NDV expressed as a subunit by a recombinant baculovirus was protective against Newcastle disease.
