As a result of human-to-pig transmission, pandemic influenza A (H1N1) 2009 virus was detected in pigs soon after it emerged in humans. In the United States, this transmission was quickly followed by multiple reassortment between the pandemic virus and endemic swine viruses. Nine reassortant viruses representing 7 genotypes were detected in commercial pig farms in the United States. Field observations suggested that the newly described reassortant viruses did not differ substantially from… 

Figures from this paper

Reassortants of pandemic influenza A virus H1N1/2009 and endemic porcine HxN2 viruses emerge in swine populations in Germany.
TLDR
The incursion of the human pandemic influenza A virus H1N1 (2009) into pig populations and its ongoing co-circulation with endemic swine influenza viruses (SIVs) has yielded distinct human-porcine reassortant virus lineages, giving rise to reassortants with as-yet-unknown biological properties and undetermined risks for public health.
Viral dominance of reassortants between canine influenza H3N2 and pandemic (2009) H1N1 viruses from a naturally co-infected dog
TLDR
This study suggests that continuous monitoring of influenza infection in companion animals may be necessary to investigate the potential of the emergence of novel influenza viruses.
Reassortment between Swine H3N2 and 2009 Pandemic H1N1 in the United States Resulted in Influenza A Viruses with Diverse Genetic Constellations with Variable Virulence in Pigs
TLDR
The vast H3N2 genetic diversity circulating in U.S. swine after 2009 has important implications in the control of this disease by the swine industry, as well as a potential risk for public health if swine-adapted viruses with H1N1pdm09 genes have an increased risk for human infection.
Experimental infection with a Thai reassortant swine influenza virus of pandemic H1N1 origin induced disease
TLDR
It is demonstrated that both the pH1N1 and rH1N 1 influenza viruses, isolated from naturally infected pigs, induced acute respiratory disease in experimentally inoculated nursery pigs.
Continual Reintroduction of Human Pandemic H1N1 Influenza A Viruses into Swine in the United States, 2009 to 2014
TLDR
It is shown that the six internal gene segments from pH1N1 viruses are likely to be sustained long term in the U.S. swine population, with periodic reemergence of pandemic hemagglutinin (HA) and neuraminidase (NA) segments in association with seasonal pH 1N1 epidemics in humans.
Genotype patterns of contemporary reassorted H3N2 virus in US swine.
TLDR
A phylogenetic analysis at a whole genome scale of North American swine influenza viruses suggests that the genetic requirements for transmission to humans may be restricted to a specific subset of swine viruses.
Reverse Zoonosis of Pandemic A(H1N1)pdm09 Influenza Viruses at the Swine/Human Interface
TLDR
Support is provided for a model where transmission of viruses from human to swine leads to rapid adaptation for the swine host which comes at the expense of optimal fitness for human.
Novel triple reassortant H1N2 influenza viruses bearing six internal genes of the pandemic 2009/H1N1 influenza virus were detected in pigs in China.
Emergence of novel reassortant H3N2 swine influenza viruses with the 2009 pandemic H1N1 genes in the United States
TLDR
The emergence of novel reassortant H3N2 SIVs demonstrates reassortment between pH1N1 and endemic Sivs in pigs and justifies continuous surveillance.
Pathogenicity and Transmissibility of Novel Reassortant H3N2 Influenza Viruses with 2009 Pandemic H1N1 Genes in Pigs
TLDR
Three H3N2 reassortant viruses that contain 3 or 5 genes from A(H1N1)pdm09 isolated from diseased pigs were pathogenic in pigs, similar to the endemic H3n2 swine virus, and an avian-like glycine at position 228 at the hemagglutinin (HA) receptor binding site is responsible for inefficient transmission.

Evidence of Human-to-Swine Transmission of the Pandemic (H1N1) 2009 Influenza Virus in South Korea
TLDR
Results indicate widespread human-to-animal transmission of pandemic (H1N1) 2009 influenza viruses in South Korea, and the significant role of pigs in the ecology of influenza viruses should be closely monitored and minimized to prevent the risk of generating viruses with greater human health concerns.
Reassortment of Pandemic H1N1/2009 Influenza A Virus in Swine
TLDR
Through systematic surveillance of influenza viruses in swine from a Hong Kong abattoir, a reassortant progeny of H1N1/2009 with swine viruses is characterized, which could produce variants with transmissibility and altered virulence for humans.
Evolution of Swine H3N2 Influenza Viruses in the United States
TLDR
Analysis of the 1999 swine H3N2 isolates showed that the internal gene complex of the triple-reassortant viruses was associated with three recent phylogenetically distinct human-like hemagglutinin (HA) molecules, which supports continued surveillance of U.S. swine populations for influenza virus activity.
Characterization of a newly emerged genetic cluster of H1N1 and H1N2 swine influenza virus in the United States
TLDR
It is indicated that the human-like H1 SIV can efficiently replicate and transmit in the swine host and now co-circulates with contemporary SIVs as a distinct genetic cluster of H1SIV.
Reassorted pandemic (H1N1) 2009 influenza A virus discovered from pigs in Germany.
TLDR
Concern is raised as to whether swine may become a reservoir for further reassortants of pandemic (H1N1) 2009 viruses with unknown implications for human health and swine production.
Identification of H2N3 influenza A viruses from swine in the United States
TLDR
The isolate and characterize genetically similar avian/swine virus reassortant H2N3 influenza A viruses isolated from diseased swine from two farms in the United States suggest that the H2n3 virus has undergone some adaptation to the mammalian host and that their spread should be very closely monitored.
Novel H1N2 swine influenza reassortant strain in pigs derived from the pandemic H1N1/2009 virus.
An investigation into human pandemic influenza virus (H1N1) 2009 on an Alberta swine farm.
TLDR
Zoonotic transmission to 2 individuals responding to the outbreak was suspected and recommendations to prevent occupational exposure are discussed.
The Role of Swine in the Generation of Novel Influenza Viruses
TLDR
Although swine can generate novel influenza viruses capable of infecting man, at present, it is difficult to predict which viruses, if any, will cause a human pandemic.
