Title: Comparative immunogenicity of three strains of Newcastle disease virus used in inactivated vaccines.
Abstract: The degree of immunity induced in chickens by inactivated Newcastle disease vaccine depends on the strain of virus, the inactivating agent, the adjuvant, and host factors such as age and the presence or absence of passive antibodies (1). Hanson et al. (3) compared the immunogenicity of 5 strains of Newcastle disease virus (NDV) in formalinized vaccines. They concluded that certain strains were much better immunogens than others, but that there was no relationship between immunogenicity and virulence or heat stability of the strain. Sullivan et al. (6), using beta-propiolactone (BPL) as the
