Evolutionary relationships among PSVs. Phylogenetic tree based on the nucleotide sequences of VP1 gene. The evolutionary history was inferred using the ML method with the GTR model with gamma-distributed rates and proportion of invariant sites (G+I) in PhyML 3.0. The percentage of replicates in which the associated virus clustered together in the bootstrap test (100 replicates) is shown next to the branches (only values >60 % are shown) in the tree. The scale bar indicates nucleotide substitutions per site. Simian sapelovirus (SSV)-1 2383 strain, SSV-2 VRDL strain and SSV-3 WUHARV strain were used as outgroups. The strains isolated in the present study are identified by â–˛
