Phylogenetic analysis of Sandfly fever Sicilian virus, Algeria, based on A) 207-nt or B) 67-aa sequence in the polymerase gene. Distances and groupings were determined by the pairwise or Kimura 2-parameter algorithm and neighbor-joining method with the MEGA v2 software program (www.megasoftware.net). Bootstrap values are indicated and correspond to 500 replications. Boldface indicates virus names that correspond to sequences determined in this study. Scale bars indicate pairwise nucleotide distances (0.1 = 10%) and Kimura 2-parameter amino acid distances (0.05 = 5%).
