Figure 3. Phylogenetic analysis of avian influenza viruses from Australia. Viruses were subtyped, and hemagglutinin genes from subtypes H5 (A), H7 (B), and H9 (C) were sequenced (boldface) and compared with isolates from other geographic locations. Only bootstrap values >50 are shown. Scale bar indicates nucleotide substitutions per site. All sequences were submitted to GenBank (accession numbers pending). LPAI, low-pathogenicity avian influenza; HPAI, highly pathogenic avian influenza.
