| identification and characterization of h2n3 avian influenza virus from backyard poultry and comparison with novel h2n3 swine influenza virus. | in early 2007, h2n3 influenza virus was isolated from a duck and a chicken in two separate poultry flocks in ohio. since the same subtype influenza virus with hemagglutinin (h) and neuraminidase (n) genes of avian lineage was also identified in a swine herd in missouri in 2006, the objective of this study was to characterize and compare the genetic, antigenic, and biologic properties of the avian and swine isolates. avian isolates were low pathogenic by in vivo chicken pathogenicity testing. seq ... | 2011 | 22312981 |
