Additional file 1.Neighbor-joining phylogenetic tree of the DENV-3 E gene corroborating the presence of two different lineages. The Tamura-Nei nucleotide substitution model was used to estimate distance matrix. Sequences obtained in present study marked with circles and boxes correspond to genotype I and III, respectively. Bootstrap values major of 50% were maintained in the tree supporting clustering in genotypes after 1000 pseudo-replications. Horizontal branch lengths are drawn to scale.
