Phylogenetic tree generated by Bayesian analysis of dengue virus 2 (DENV-2) Cosmopolitan genotype complete envelope gene. The GenBank accession number, virus sub-genotype, strain, collection country and year are noted. The DENV-2 sequences from Saudi Arabia are marked in red. Bootstrap values (1,000 replicates, not shown for less than 75%) of Bayesian analyses, maximum likelihood and neighbor-joining are shown above/below the main lineages. The scale-bar indicates 0.01 substitutions per site. Dark gray and light gray indicate DENV-2 Cosmopolitan 1 sub-genotype and DENV-2 Cosmopolitan 2 sub-genotype, respectively. C1, Cosmopolitan 1 sub-genotype; C2, Cosmopolitan 2 sub-genotype.
