Figure 1. — Phylogenetic analyses of H3N2 avian influenza viruses isolated from 2009 to 2014 in China. The phylogenetic trees of HA (a) and NA (b) were rooted to A/Duck/Alberta/78/1976 (H3N2) and A/Turkey/England/1969 (H3N2), respectively. The phylogenetic trees of PB2 (c), PB1 (d), PA (e), NP (f), M (g), and NS (h) were rooted to A/Equine/Prague/2/56 (H7N7). The viruses sequenced in this study are underlined in the phylogenetic tree. Abbreviations: DK, duck; CK, chicken; CSD, common shelduck; NS, northern shoveler; EN, environment; WBM, white-backed munia; WS, whooper swan; SW, swine; EQ, equine; ML, mallard; AB, aquatic bird; SBD, spot-billed duck; TK, turkey; GG, garganey; VS, velvet scoter; WWF, wild waterfowl; CT, common teal; PTD, pintail duck; GW, gadwall; RSD, ruddy shelduck; WD, wild duck; PT, pintail; MLD, mallard duck; BHG, bar-headed goose; GL, gull; MD, migratory duck; GS, goose; HuB, Hubei; CQ, Chongqing; GX, Guangxi; FJ, Fujian; HuN, Hunan; VN, Vietnam; GD, Guangdong; ZJ, Zhejiang; HK, Hong Kong; SC, Sichuan; XJ, Xinjiang; XH, Xianghai; SH, Shanghai; JS, Jiangsu; HeB, Hebei; DT, Dongting; AH, Anhui; NC, Nanchang; ST, Shantou; DG, Dongguan; WZ, Wenzhou; QH, Qinghai; JX, Jiangxi.
