Figure. Phylogenetic tree of H9 gene of influenza A(H9N2) viruses from Myanmar and reference viruses. Phylogenetic trees were constructed by using MEGA version 6.0 (http://www.megasoftware.net/) and a neighbor-joining algorithm with the Kimura 2-parameter model and 1,000 replications of bootstrap analysis. Only bootstrap numbers >70% are shown. Black circles represent isolates from this study, and open circles represent human H9N2 isolates. Virus clades are indicated at right. Scale bar indicates nucleotide substitutions per site.
