| Abstract |
Inactivated Newcastle disease virus (NDV), infectious bronchitis virus (IBV), egg drop syndrome (EDS) and P. multocida (PM) were incorporated into water in oil emulsion vaccines alone (monovalent) or as in combined (tetravalent) vaccine immunological response to the new tetravalent vaccine was evaluated by injecting groups of susceptible chickens with either tetravalent or monovalent vaccine. Results revealed that humoral immunity with the new tetravalent vaccine were never inferior to those obtain with the monovalent ones. There were no practical differences in the percentage and duration of the protective immunity induced with NDV vaccine and P. multocida vaccine upon challenge with velogenic viscerotropic Newcastle disease virus (VVNDV) or PM antigen. The tetravalent (NDV+ IBV+ EDS and FC) inactivated vaccine was safe, immunogenic and produced satisfactory dual protection against NDV, IBV, EDS and P. multocida infections
