Figure 2

Phyogenetic analysis of avian influenza virus H7 (A) and N3 (B) genes. Trees were generated with MEGA software (8) by using the neighbor-joining method (9). Evolutionary distances were computed by using the method of Nei and Gojobori (10). Percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) is shown next to the branches. Scale bars indicate substitutions per site.
