Maximum likelihood phylogeny based on the complete coding region sequencing of 9 Brazilian DENV-2, 1990–2008.

<p>Black circles represent DENV-2 sequences generated in this study. Strains representative from the four genotypes available in Genbank (<a href="http://www.ncbi.nlm.nih.gov" target="_blank">www.ncbi.nlm.nih.gov</a>) were used for the comparison, DENV-1, DENV-3 and DENV-4 strains were used as outgroup to root the trees. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches. DENV strains used were named as follows: Country/strain number/state/year. RJ: Rio de Janeiro and CE: Ceará.
