From: Emergence of human-like H3N2 influenza viruses in pet dogs in Guangxi, China
Phylogenetic trees of eight gene segments of two H3N2 CIVs and reference isolates. The trees were generated with the MEGA 5.2 program using neighbor-joining analysis. The bootstrap percentages are shown above the nodes that were supported in >70% of 1000 replicates. The viruses isolated in our study are shown in black round circles. The phylogenetic trees are shown in (a) HA gene, (b) NA gene, (c) NP gene, (d) PA gene, (e) PB1gene, (f) PB2 gene, (g) M gene, and (h) NS gene.
