摘要： We previously reported a novel Asia-4 lineage of canine distemper virus (CDV) in China based on the H gene. In the present study, a Chinese CDV NJ(11)2 strain of the Asia-4 lineage from Nanjing, China was isolated and its whole genome sequence was obtained. The CDV NJ(11)2 strain clustered with the Thai strains of the Asia-4 lineage in the phylogenetic tree of the complete genome. Phylogenetic analysis based on six individual genes also revealed that the CDV NJ(11)2 strain belonged to Asia-4 lineage. According to the individual N and H genes, two Chinese strains XJ4 from Xinjiang and C11 from Chengdu were clustered with the Asia-4 lineage. These results suggested that the Asia-4 lineage of CDV appeared in the three regions of China. Interestingly, Chinese BJ16B35 strain was identified as a novel putative recombinant virus from a major parent virus of the Asia-1 lineage and a minor parent virus of the America-1 lineage. The first genome sequence of Chinese Asia-4 lineage of CDV contributes to the knowledge of the evolution and molecular epidemiology of CDV infection.
