Phylogenetic tree of the DENV-4 E gene isolated in Guangzhou between 2001 and 2010. Fourteen sequences from isolated strains and 11 reference sequences from GenBank were aligned using ClustalW. Phylogenetic trees were constructed with the maximum parsimony and maximum likelihood methods with Kimura 2-parameter corrections of multiple substitutions. Guangzhou isolates are indicated with a black triangle.
