This study aimed to investigate the immunogenicity of Newcastle disease virus (NDV) in specificpathogen-free (SPF) chickens. The NDV was inactivated using either Binary ethyleneimine (BEI) or Electrolysed water-Catholyte-Anolyte (ECA). Complete inactivation of NDV occurred after 24 hours with either BEI or ECA. Prepared inactivated NDV vaccines were tested for their efficiency in generating hum...

irst well defined case of the mutagenic effectiveness of chemicals was Tyet:ied for mustard gas treatment of Drosophila by AUERBACH and ROBSON ( 1946). Chemical mutagenesis studies have since been extended to a number of biological systems, including bacteria, fungi and higher organisms. AUERBACH (1965) has discussed the development of chemical mutagenesis in the last 20 years. The application ...
