A phylogenetic approach was used to identify genetic variants of DENV-3 subtype III that may have emerged during or after its expansion throughout South America. We sequenced the capsid, premembrane/membrane and envelope genes from 22 DENV-3 strains isolated from Venezuela, Bolivia, Ecuador and Peru between 2000 and 2005. Phylogenetic analysis showed that the isolates sequenced in this study formed three clades within subtype III: one with the isolates from Venezuela, one with the Bolivian isolates and one with the isolates from Ecuador and Peru.
