Figure 2

Phylogenetic relationships of the hemagglutinin (HA) gene of influenza virus (H5N1) isolates from Kuwait in 2007. Numbers at nodes indicate neighbor-joining bootstraps >60, and Bayesian posterior probabilities >95% are indicated by thickened branches. Analyses were conducted with nucleotide positions 1–963 of the HA gene. The HA tree was rooted to Gs/Guangdong/1/1996. Labels to the right of the tree refer to World Health Organization (H5N1) clade designations (14). Ck, chicken; Dk, duck; Gs, goose, MDk, migratory duck; Qa, quail; Ty, turkey.
