Phylogenetic relationship of the HA and NA genes of the virus isolates. The HA (A) and NA (B) phylogenetic trees were constructed by the NJ method with TN93 nucleotide substitution model. Analyses were based on nucleotides 13-1695 and 4-1356 for the HA and NA genes, respectively. Bootstrap values under 50% are not shown. Scale bars indicate number of nucleotide substitutions per site. Viruses isolated from live birds are shown in open squares, while those from dead birds are shown in closed squares. Taxon (virus) names are followed by months when they were isolated and are colour-coded by district of origin: Sleman (red), Bantul (green), Magelang (blue) and Kulon Progo (purple) and sequences obtained from GenBank (black). IDN/6/05-like viruses are shaded in grey. The 2.1.3 clade viruses identified in this study are clustered into three groups; I, II and III (shaded in blue).
