“…In Italy, the reassorted virus was also derived from pandemic human virus but carried an NA gene similar to that of H1N2 SIV (20). Similar situation occurred in 2010 in Canada, where new swine H3N2 virus reassorted with pdm H1N1 2009 virus emerged in swine and mink (33). The natural co-infection involving pandemic strain and seasonal H1N1 viruses has been also reported in human (8).…”

The outbreaks of pandemic H1N1 influenza A virus (pdm-like H1N1 2009), detected for the first time in farrow-to-finish farms in Poland, were described. The nasal swabs and lung tissue collected from diseased/dead animals were tested using molecular techniques (RRT-PCR, MRT-PCR, RT-PCR, SSG-PCR, sequencing) and virus isolation. The amplification of the genetic material extracted from the tested samples confirmed the presence of the M1 gene sequence of type A influenza virus. Using MRT-PCRs no products characteristic for HA and NA of any swine influenza virus subtypes were obtained. Using SSG-PCR, products specific for pandemic HA and NA gene fragments were detected. Six new pdm-like H1N1 2009 strains were isolated and characterised. Phylogenetic analysis of the HA and NA genes revealed that they belong to one lineage with the pandemic strain A/California/04/2009 and other human strains, including human strains isolated in Poland in 2011.

“…Moreover, in some countries the reassorted pdm H1N1 2009 virus was isolated from pigs (11,20,25,33,35). In Germany, pig herds were investigated in greater details since 2009.…”

“…Within the last few years, several new reassortant swine influenza viruses have been detected throughout Europe, Asia and the USA (Breum et al, 2013;Moreno et al, 2011;Pascua et al, 2013;Starick et al, 2011Starick et al, , 2012Tremblay et al, 2011), with many carrying segments from enzootic swine influenza viruses and the H1N1pdm09 virus.…”
