Phylogenetic tree based on the long NS5 fragment of the Flavivirus genus. A fragment of 937 bp of the NS5 gene was used to infer the tree. The phylogenetic analysis includes 35 reference sequences from GenBank and 20 from this study. Unpublished sequences are given in bold, Piedmont sequences in italics. The nucleotide substitution model used as a prior for the MCMC was GTR + I + G according to the jModelTest2 results. The tree is mid-point routed, and the scale of branch length is expressed as substitution per site. Taxa are divided into four clusters, according to the literature: IS insect-specific; NK no-known vector; MB mosquito-borne; TB tick-borne.
