Immune response to monovalent and bivalent Newcastle disease and infectious bronchitis inactivated vaccines.

Abstract

Inactivated oil emulsion Newcastle disease (ND) and infectious bronchitis (IB) vaccines were prepared and evaluated in both monovalent and bivalent form. By using such vaccines as secondary boosters an enhanced immune response was produced for up to 10 weeks, at which time there was a high degree of resistance to challenge with IB virus in the bivalent… (More)
