Phylogenetic tree of Flavivirus genus. A portion of 226 bp on the NS5 gene was used to infer the tree. Internal nodes are labeled with the posterior probability of the node. The tree was built using MrBayes Software and the following parameters: GTR + G evolutionary model, 3,000,000 generations, sample frequency = 100, burn-in = 3000. Taxa order in the tree is adjusted according to the uncorrected p genetic distance between samples.
