FIG 1.

Spread of SINV-I from Africa to Europe. Shown is a Bayesian phylogenetic tree of SINV-I based on concatenated nucleotide ORF sequences (MrBayes). The colors indicate Sweden (green); Finland (blue); Germany (red); Egypt, Israel, and Saudi Arabia (pink); Kenya and the Central African Republic (orange); Slovak Republic (light blue); Italy (gray); and South Africa (purple). The roots in orange indicate that SINV-I originated in central Africa. Main SINV-I dispersal routes from Africa to and within northern/central Europe are indicated with dashed lines. L, N, E, and S represent locations in Sweden (Lövånger, Nedre Dalälven, Edsbyn, and Sundsvall, respectively). Posterior probability values above 0.95 are shown for the branches. Dots indicate the sequences generated from this study.
