Canine Parvovirus type 2 (CPV-2) is a virus that causes acute diarrheal enteritis in dogs. CPV-2 is a DNA virus and based on the VP2 gene sequence, CPV-2 is clasified into CPV-2a, CPV-2b and CPV-2c. Currently, CPV-2c is the most popular variant circulating in the world as well as in Vietnam. In this study, the genome sequences of eight canine Parvovirus strains isolated in some northern provinces of Vietnam during 2018-2020 were sequenced. The results of genome sequencing of the Parvovirus strains have obtained genetic sequences of 4269 nucleotides (nt) in length, in which the gene sequence coding for the open reading frame (ORF) corresponding to the non-structural proteins was 2007 nt and structural proteins was 2256 nt in length. The phylogenetic analysis based on the full genome sequences showed that all eight present canine Parvovirus strains belonged to CPV-2c and shared the same evolutionary brand with clade Asia-4. The whole genomic sequence data of canine Parvovirus obtained in this study will be an important source for any spatial and temporal genetic evolution studies of canine Parvovirus strains circulating in Vietnam.
