The low-pathogenic avian influenza subtype of the H9N2 virus circulates in domestic poultry and wild birds throughout the world, causing severe morbidity and mortality in commercial chickens during coinfection with other pathogens , resulting in enormous losses. This kind of virus has been prevalent since the H9N2 virus was first identified in China in(More)
Infection of poultry with diverse lineages of H5N2 avian influenza viruses has been documented for over three decades in different parts of the world, with limited outbreaks caused by this highly pathogenic avian influenza virus. In the present study, three avian H5N2 influenza viruses, A/chicken/Shijiazhuang/1209/2013, A/chicken/Chiping/0321/2014, and(More)
OBJECTIVE Low pathogenic avian influenza (LPAI) H9N2 subtype virus has been prevalent in domestic poultry in China over two decades. This study was to determine the genetic evolution trend of H9N2 avian influenza virus (AIV) under immune pressure of vaccine. METHODS H9 HA sequences of 40 isolates from the present study and 136 pandemic strains and 7(More)
