| Abstract: | Antibody response of recombinant fowlpox virus (FPV) was studied in chickens inoculated with the virus in the presence or absence of antibodies against Newcastle disease virus (NDV) or FPV. In the case of NDV, high hemagglutination-inhibition titers to NDV were obtained when the antibody was present. No immune response to NDV was observed in the chickens previously vaccinated with FPV. |
