    *Lineages of each gene are partially shown in online Technical Appendix Figures 1–7 ( Lineage A of each gene is likely from H9N2 subtype avian influenza virusess. Any 2 viruses with >1 gene of different lineages belong to different genotypes. PB, polymerase basic protein; PA, polymerase acidic protein; HA, hemagglutinin; NP, nucleocapsid protein; NA, neuraminidase; M, matrix protein; NS, nonstructural protein.
