From: New H6 influenza virus reassortment strains isolated from Anser fabalis in Anhui Province, China
Phylogenetic analysis by maximum likelihood of inner genes of H6 subtype AIVs isolated in Anhui Province, 2014: (a) PB2, (b) PB1, (c) PA, (d) NP, (e) M, and (f) NS. The colours of the virus names listed in the PB2, PB1, PA, NP, M, and NS trees match those used in the genotype table. The phylogenetic trees of inner genes were rooted to A/Turkey/Canada/1/1963 (H6N8). The nucleotide sequences of the viruses listed in black were downloaded from GenBank; the viruses listed in red, yellow, or green were sequenced in this study. The sequences shown in cyan and italics were obtained from a paper by Wang GJ. Abbreviations: CK, chicken; DK, duck; GS, goose; SW, swine; WDK, wild duck; WB, wild bird; WGS, wild goose; EN, environment
