Isolation of Highly Pathogenic Avian Influenza H5N1 Virus from Saker Falcons (Falco cherrug) in the Middle East
Figure 1
Phylogenetic relationships based on the HA (nucleotides 1–1684) genes of the
Fa/SA/05 and Fa/KW/07 viruses. The nucleotide sequences were analyzed by PHYLIP
3.65 software using the neighbor-joining method with 100 bootstraps. The tree
was rooted to the HA gene of A/Chicken/Hong Kong/220/97. Viruses in bold red
type were characterized in this study. Clades are indicated.
