From: A new reassortment of influenza A (H7N9) virus causing human infection in Beijing, 2014
Phylogenetic analysis of HA, NA, PB2 and M genes of H7N9 influenza viruses.
The phylogenies were inferred by the Maximum Composite Likelihood model of the Neighbor-Joining algorithm with the software MEGA5 and 1000 bootstrap replicates were applied. The branches for the H7N9 viruses are in red; H7Nx (A), HxN9 (B) and H9N2 (C,D) viruses are in blue; the red dots represent the Beijing isolates. The blue dots represent the representative isolates, A/Anhui/1/2013(H7N9) and A/chicken/Jiangsu/SC537/2013(H7N9).
