Resumo: |
Dengue viruses (DENV) serotypes 1, 2, 3, and 4 have been causing yearly outbreaks in Brazil. Nevertheless, the population structure of the viruses transmitted in Goiás state is not well understood. In this study, we investigated the phylogenetic pattern of DENV samples identified in Goiânia, Goiás, Brazil during the 2012/2013 epidemic. Therefore, the entire region of the gene of the envelope (E) protein (1485bp) of 16 DENV-1 samples as well as partial region of this gene (363bp) of seven DENV-4 samples were sequenced. Phylogenetic analysis showed that DENV-1 belongs to the genotype V and presents itself divided into two clades, suggesting co-circulation of two distinct lineages in this region. Still, the molecular analyzes indicated a significant change in the amino acid level E348 position. For DENV-4, the sequences were segregate in a monophyletic group and are classified as genotype II American subclade. The molecular and phylogenetic analysis showed that the region suffered multiple introductions by dengue virus. This is the first report of co-circulation of two lineages of DENV-1, and the circulation of DENV-4 in Goiás state. |
