Figure. Schematic diagram of the H5 clade 2.3.4.4 highly pathogenic avian influenza virus genotypes identified in this study, United States, 2014–2015. Reassortant H5N8 comprises Eurasian PB2, PA, HA, NP, M, and NS gene segments, and North American PB1 and PA gene segments; reassortant H5N2 comprises Eurasian PB2, PA, HA, M, and NS gene segments, and North American NA, PB1, and NP gene segments; reassortant H5N1 comprises Eurasian HA, NP, M, and PB2 gene segments and North American NA, NS, PA, and PB1 gene segments. HA, hemagglutinin; LPAI, low-pathogenicity avian influenza; M, matrix; NA, neuraminidase; NP, nucleoprotein; NS, nonstructural; PA, polymerase acidic; PB1, polymerase basic 1; PB2, polymerase basic 2.
