Dear Editor,Avian influenza A (H9N2) virus plays a crucial role in interspecies transmission between animals and humans due to its wide host range, adaptation in mammals and the diversified gene reassortments. Since 1990s, two lineages of H9N2 virus, A/Duck/HK/Y280/97 (Y280-like)and A/Quail/HK/G1/97 (G1) have established in domestic poultry in China and are now widespread in the
