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 hemagglutinin [HA] and neuraminidase [NA] genes) and to pH1N1 for all the other genes (M, NP, NS, PB1, PB2, and PA). Data indicate that the swH3N2/pH1N1 virus can be found in several pigs that are housed at different locations.
2010 年末,在加拿大的猪群中检测到了一种猪源 H3N2(swH3N2)和甲型流感病毒的 2009 年(pH1N1)大流行株(swH3N2/pH1N1)的重配病毒。同时,基于部分病毒基因组测序,在加拿大水貂中也检测到了类似的病毒。新的 swH3N2/pH1N1 病毒基因的起源与北美的 swH3N2 三重重配簇 IV(针对血凝素 [HA] 和神经氨酸酶 [NA] 基因)和 pH1N1 有关(针对所有其他基因 [M、NP、NS、PB1、PB2 和 PA])。数据表明,这种 swH3N2/pH1N1 病毒可在不同地点饲养的多只猪中找到。
