Figure 2. . Phylogenetic relationships of hemagglutinin genes of avian influenza (H9N2) viruses (boldface) isolated in Bangladesh. Full-length DNA sequencing, starting from the first codon, was used. The phylogenetic trees were generated by PhyML (30) within the maximum-likelihood framework. Numbers above the branches indicate bootstrap values; only values >60 are shown. Boldface italics indicate prototype subtype H9N2 viruses from the Ck/Bei and G1 clades. Scale bar indicates distance between sequence pairs.
