Phylogenetic relationships based on the complete VP2 gene of CPV-2 between. Vietnamese isolates and reference strains. HN: HaNoi (North Vietnam), DN: DaNang (Central Vietnam), HCM: HoChiMinh city (South Vietnam), CPV: Canine parvovirus, FPLV: Feline panleukopenia virus. The analysis was performed employing the maximum likelihood method based on 1000 replicates using MEGA 6 software. CPV variants are indicated by □, ◆, ◯, ▲, ■, ●, ▼ and △ for the vaccine strain, FPLV, CPV-2, CPV-2a, new CPV-2a, CPV-2b, new CPV-2b, and CPV-2c, respectively. Gray underlay represents CPV-2 isolates in the present study
