Phylogenetic relationships of the hemagglutinin (HA) (A), neuraminidase (NA) (B), polymerase basic protein 2 (PB2) (C), and nonstructural (NS) (D) genes of the 7 influenza (H5N1) viruses. Nucleotide sequences were analyzed by using the neighbor-joining method with 100 bootstraps. The HA phylogenetic tree was rooted to the HA gene of A/goose/Guangdong/1/96 (H5N1) virus. The NA phylogenetic tree was rooted to the NA gene of Puerto Rico/8/34 (H1N1) virus. The PB2 and NS trees were rooted to the PB2 and NS genes of B/Lee/40 virus.
