Phylogenetic analysis of the VP1 gene sequence of SAFVs.

<p>The trees were constructed using the neighbor-joining method. Each strain is labeled by number of genotype, accession number and strain name. Genotype I (SAFV-1) is highlighted in color, sublade 1 in blue, and subclade 2 in red. The triangle represents the prototype SAFV-1 strain. Circles represent the SAFV-1 strains identified in this study.
