RESUMO
To genetically characterize dengue 2 (DEN-2) viruses in Oaxaca, Mexico, the C protein, and a portion of the prM protein genes of 8 isolates from the 2001 DEN epidemic were sequenced. The sequences were compared to those of prototype DEN-2 viruses from various parts of the world. Phylogenetic analysis suggested that the 2001 isolates of DEN-2 were of the American/Asian genotype and were most similar to the Jamaica and Venezuelan isolates MARA3, LARD1996 and LARD1910. Molecular analyses confirmed the origin of the isolates. This study indicates that DEN-2 strains of American/Asian genotype probably from Southeast Asian are circulating in Oaxaca.
