Genetic characterization of a porcine H1N2 influenza virus strain isolated in Germany.
We examined selected influenza virus strains from various outbreaks of respiratory diseases among pigs in Germany. Besides H3N2 and H1N1 subtypes presently circulating in Europe, an H1N2 influenza virus was isolated in 2000. Sequence analysis of hemagglutinin, neuraminidase and matrix genes indicated that this virus is a reassortant of human H1N1 and human H3N2 strains with an internal gene, the M gene of avian origin. It is a result of a multiple reassortment event.
