The homology of the nucleotide sequences and genetic variation analysis of NDV strains suggested that mere were obvious divergence in gene lever among NDV vaccine strains and epizootic strains isolated from different areas and different ages.The divergence may have effect on amino acid and structure and function of protein in some extent and lead to difference of immunogenicity ,which was one of reason being difficult in preventing from ND.
