Phylogenetic and pathogenic analysis of Newcastle disease virus isolated from house sparrow (Passer domesticus) living around poultry farm in southern China.
House sparrow (Passer domesticus) is one of the most widely distributed wild birds in China. Five Newcastle disease virus (NDV) strains were isolated from house sparrows living around the poultry farms in southern China. These isolates were characterized by pathogenic assays and phylogenetic analysis. The results showed that all NDV isolates except one were velogenic and virulent for chickens. These four virulent strains for chickens possess the amino acid sequence (112)R/K-R-Q-K/R-R-F(117) in the F(0) cleavage site which is typical of velogenic NDV. Phylogenetic analysis indicated that these isolates belong to genotype VII and were closely related to the strains which were isolated from NDV outbreaks in chickens since 2000. One isolate of NDV from house sparrow belong to genotype II and was proved to be vaccine strain (Chicken/U.S./LaSota/46). The result of this study proved that house sparrow can carry the virulent NDV strains and the same genotype of viruses that are circulating in poultry are existing in house sparrows living around poultry farm in southern China.
