Genetic constellations of the five viruses used in this study. Abbreviations: PB2, polymerase basic 2; PB1, polymerase basic 1; PA, polymerase acidic; HA, hemagglutinin; NP, nucleoprotein; NA, neuraminidase; M, matrix; NS, nonstructural; TRIG, triple-reassortant internal genes, which are derived from swine (M, NS and NP), human (PB1) and avian (PB2 and PA) influenza viruses forming a constellation of genes that is well conserved in North American swine influenza viruses.
