Abstract excerpt
In our research, the molecular evolutions of NDV F and HN genes were analyzed. The phylogenetic analyses of NDV sequences indicated that NDV could be divided into two genotypes: Class I (lentogenic strains) and Class II (velogenic or mesogenic strains). Each genotype possesses high gene homology. Furthermore, the selected pressure analysis showed that the dN/dS of velogenic, mesogenic NDV strains F gene was...
