Figure 1. Phylogenetic tree of DENV2 Brazilian samples.

Figure 1

The maximum clade credibility (MCC) tree was inferred for 18 partial envelope sequences from the city of Santos, State of São Paulo and DENV2 reference sequences. The posterior probabilities of the key nodes are depicted above the respective node. The time of the most recent common ancestor (TMRCA) of the more recent lineage, American/Asian genotype and serotype 2, with upper and lower intervals in parenthesis, are depicted in bold in the respective nodes. Black full circles identify the sequences generated in this study. Brazilian sequences are identified according to the region of origin: “North“ (from Northeast region) and “SP” or “RJ” (from Southeast region). When available, the sampling year was described in the end of the sequences.
