Figure 1 The phylogenetic analysis of SVV based on polyproteins. Neighbor-joining tree generated with 1000 bootstrap samplings (MEGA 6.06). The diamond shape represents the strains in this study. The icon before the accession number indicates the host source of the sequence. At present, only SVA/GD/China/2018 has been derived from diseased buffalo and is in the same branch and closely related to the wild boar-origin strain, Sichuan HS-01.
