Figure. Phylogenetic tree based on the envelope genome sequence of selected dengue virus type 3 (DENV-3) strains. The tree was rooted to DENV-1, DENV-2 and DENV-4. Multiple sequence alignments were performed, and the tree was constructed by using the neighbor-joining method. The percentage of successful bootstrap replication is indicated at the nodes. DENV-3 genotypes are indicated on the right. The isolated DENV-3 strains, D3/Hu/Tanzania/NIID08/2010 strain (Tanzania2010) and D3/Hu/Côte d'Ivoire/NIID48/2008 strain (Côte d’Ivoire2008), are indicated with arrowheads. Scale bar indicates nucleotide substitutions per site.
