title: H9N2 avian influenza virus-derived natural reassortant H5N2 virus in swan containing the hemagglutinin segment from Eurasian H5 avian influenza virus with an in-frame deletion of four basic residues in the polybasic hemagglutinin cleavage site.
abstract: We isolated a novel H5N2 avian influenza virus from swans in China. The virus was derived from a widespread H9N2 avian influenza virus but acquired the hemagglutinin gene from Eurasian H5 subtype with a naturally occurring in-frame deletion of four basic residues in the polybasic hemagglutinin cleavage site.
