Emergence of a new Swine H3N2 and Pandemic (H1N1) 2009 Influenza A Virus Reassortant in Two Canadian Animal Populations, Mink and Swine
November 7, 2011 —
A swine H3N2 (swH3N2) and pandemic (H1N1) 2009 (pH1N1) influenza A virus reassortant (swH3N2/pH1N1) was detected in Canadian swine at the end of 2010. Simultaneously, a similar virus was also detected in Canadian mink based on partial viral genome sequencing. The origin of the new swH3N2/pH1N1 viral genes was related to the North American swH3N2 triple reassortant cluster IV (for HA and NA genes) and to pH1N1 for all the other genes (M, NP, NS, PB1, PB2, PA). Data indicate that the swH3N2/pH1N1 can be found in several pigs that are housed at different locations.
