Abstract
In October 1999, H4N6 influenza A viruses were isolated from pigs with pneu monia on a commercial swine farm in Canada. Phylogenetic analyses of the se quences of all eight viral RNA segments demonstrated that these are wholly avian influenza viruses of the North American lineage. To our knowledge, th is is the first report of interspecies transmission of an avian H4 influenz a virus to domestic pigs under natural conditions.
