Abstract: Natural Reassortment of Eurasian Avian-like Swine H1N1 and Avian H9N2 Influenza Viruses in Pigs, China
Several zoonotic influenza A viruses detected in humans contain genes derived from avian H9N2 subtypes. We uncovered a Eurasian avian-like H1N1 swine influenza virus with polymerase basic 1 and matrix gene segments derived from the H9N2 subtype, suggesting that H9N2 viruses are infecting pigs and reassorting with swine influenza viruses in China.
