Abstract:
Thirteen isolates of Class I Newcastle disease virus obtained from healthy poultry in China during 2008 were characterized genotypically in this study. All the isolates were proved to be lentogenic strains based on the deduced amino acid sequence of the Fusion protein gene. Molecular epidemiological analysis showed that 13 isolates could be subdivided into 2 distinct genotypes, 11 isolates belonged to genotype 2, and other 2 isolates belonged to genotype 3. Results indicated two genotypes of Class I Newcastle disease virus might widely exist in domestic poultry in China.
