Phylogenetic analyses of Saffold viruses (SAFVs). Phylogenetic analysis of SAFV-2. Strains from Denmark are named by using the isolation numbers assigned for the study, then the country of origin and year of sampling in parentheses. The 2 subgroups (DK-A and -B) are shown. The tree is rooted by using SAFV-1 outgroup sequence accession no. EF165067. Bootstrap values >70% are shown. DK, Denmark; US, United States. Scale bar represents nucleotide substitutions per site.
