During swine influenza virus surveillance in pigs in Tianjin, China, from 2006 to 2013, we isolated human-like H1N1, classical swine H1N1, Eurasian avian-like swine H1N1 and novel triple-reassortant H1N1 swine influenza viruses containing genes from 2009 pandemic H1N1 (PB2, PB1, PA and NP), Eurasian swine (HA, NA and M) and triple reassortant swine (NS) lineages.The emergence of novel triple-reassortant H1N1 swine influenza viruses emphasizes the importance of further cominuous surveillance.
