Phylogenetic analysis revealed three distinct Eurasian lineages: BJ\/94\u2010like (HA, NA), G1\u2010like (PB2, MP), and F98\u2010like. Notably, viral genes diverged into two major branches (A\/B), with the A branches of HA, PB2, PA, and NS further subdivided into A1\/A2 sublineages. In addition to the A and B branches, the viral genes of several isolates formed independent phylogenetic branches. Some of the viral genes clustered together with H9N2 viruses from the poultry\/environmental strains in China and Japan, and some viral genes (e.g.,\n                      <jats:italic>PB2<\/jats:italic>\n                      ,\n                      <jats:italic>PB1<\/jats:italic>\n                      ,\n                      <jats:italic>MP<\/jats:italic>\n                      , and\n                      <jats:italic>NS<\/jats:italic>\n                      ) showed close phylogenetic relationships with human\u2010infecting H9N2\/H7N9 viruses.
