Genetic variation of the hemagglutinin of avian influenza virus H9N2.

Journal of medical virology - 1 May 2011

Song Xiao-feng, Han Ping, Chen Yi-Ping Phoebe

Abstract excerpt

Avian influenza virus H9N2 has become the dominant subtype of influenza which is endemic in poultry. The hemagglutinin, one of eight protein-coding genes, plays an important role during the early stage of infection. The adaptive evolution and the positively selected sites of the HA (the glycoprotein molecule) of H9N2 subtype viruses were investigated. Investigating 68 hemagglutinin H9N2 avian influenza virus...
