Phylogenetic trees of the gene segments HA, NA, PB2, PB1, PA, NP, M, NS (from A-H respectively), showing the evolutionary relationship between the studied isolates (red circles) and the reference AIVs from GenBank (black squares) and the WHO recommended vaccine strains (black triangles). The trees were obtained using the maximum likelihood (ML) method, using the general time reversible (GTR) nucleotide substitution model, with the MEGA X, version 10.1.8. Numbers at the nodes indicate the bootstrap values (1000 replicates)
