The phylogenetic tree of DENV-2 partial envelope (E) gene sequence isolates from Klang Valley 2011-2012. The tree was constructed by the neighbor-joining method (MEGA 5.2) with bootstrap 1000 replications. The 15 isolates DENV-2 were aligned with 15 references sequences global from GenBank. The tree was rooted with DENV-1 from Hawaii, USA as out-group, an accession number is AF231720. The Malaysia isolates designated in black triangle and reference sequences abbreviations in serotype/country/year of isolation and follow by GenBank accession number.
