Abstract: A strain of virus was isolated and identified from feces of a suspected canine parvovirus (CPV) infected dog.It was eventually identified as CPV using electron microscope examination,hemagglutination (HA) test,animal regression experiment and molecular biology idenfication,designated as BJ-24 strain.The VP2 gene sequence analysis of BJ-24 strain showed that BJ-24 strain belonged to CPV-2a subtype.The analysis of VP2 gene indicated that the BJ-24 VP2 gene shared higher homology of nucleotide with 19 CPV strains available in GenBank and were more than 98.7%.The highest homology was 100.0% with CPV-JS2 strain.Phylogenetic tree analysis showed that BJ-24 strain belonged to China cluster and there was the closest distant between BJ-24 strain and CPV-JS2 strain.This study provided the basic evidence for further study on molecular epidemiology in Beijing and laid the solid foundation for developing vaccine and preventing the spread of CPV.
