Abstract
Wild bird fecal samples collected and characterized by the USDA as part of a national surveillance effort were sequenced to study the genetic relatedness of avian, swine, and human H1 and N1 subtypes. Our results find that the 2009 H1N1 human outbreak is closely related to swine virus, but falls into different clades in the H1 and N1 trees. Further, there is evidence of multiple viral genetic exchanges between birds and swine. Ongoing research across host species contributes to an understanding of the circulation of influenza viruses.
