Pandemic Potential of Reassortant Swine Influenza A Viruses
<p>Influenza A viruses are capable of causing disease in several species, including birds, humans and swine. Host specificity of the viruses is not absolute, and is influenced by a range of factors. Swine play a pivotal role in the interspecies transmission of influenza A viruses, as they are …

Investigation of Swine Influenza Virus Genetic Diversity and Evolution
<p>Influenza A exists primarily in a waterfowl reservoir and readily infects numerous avian and mammalian species. In swine, numerous subtypes and antigenic lineages of swine influenza virus (SIV) co-circulate. The reassortment of viral RNA segments in cells infected by multiple viruses can lead to …

Epidemiology of Swine Influenza Virus in Cattle (Respiratory Diseases)
Various strains of influenza viruses have been isolated from ruminants and antibody responses detected by serological tests. The widespread occurrence of swine influenza virus (SIV) justifies studies to assess the importance of other animals that cohabitate with swine as potential reservoirs.

Novel insights in the serodiagnosis and pathogenesis of swine influenza
Het varkensinfluenza virus veroorzaakt wereldwijd een respiratoire aandoening bij varkens die sterke gelijkenissen vertoont met influenza bij de mens. De belangrijkste doelstellingen van dit proefschrift waren ten eerste om in detail de respons van cytokines en acute fase eiwitten na een …

A porcine model for polymicrobial respiratory infections with swine influenza virus and Staphylococcus aureus
Influenza A virus (IAV) is a significant problem worldwide, and respiratory disease is further complicated by secondary bacterial infection. The emergence of highly pathogenic strains of IAV in conjunction with the increase of antibiotic-resistant bacteria threatens human health. A large-animal …

Development of an Antibiotic Resistance Free Bivalent Vaccine Against Swine Brucellosis and Swine Influenza
… diseases of both bacterial and viral origin. Swine brucellosis caused by Brucella suis and swine influenza caused by Influenza A virus affect both domestic and feral swine populations. Both the diseases have zoonotic potential to cause disease in humans with serious complications apart from …

Reverse Zoonosis of Pandemic A(H1N1)pdm09 Influenza Viruses at the Swine/Human Interface
<p>The 2009 pandemic influenza A(H1N1)pdm09 virus emerged from the swine population. Despite frequent zoonotic events, swine influenza viruses had not become established in humans previously and little is known about host-barriers which prevent swine influenza viruses from efficiently infecting …

INTERSPECIES TRANSMISSION AND HOST RESTRICTION OF INFLUENZA A VIRUSES
Type A influenza viruses can infect both mammals including humans, pigs, horses, cats, dogs, ferrets, and sea mammals as well as domestic and wild birds. Although influenza A viruses shows host range restrictions, interspecies transmission have been documented at many occasions. Swine have been …

Influenza A Virus PB1-F2 Protein: its Role in Pathogenesis
Influenza A virus (IAV) causes annual seasonal epidemics and occasional pandemics resulting in significant levels of mortality and socio-economic costs worldwide. PB1-F2 is a small non-structural protein encoded by an alternate +1 open reading frame in the PB1 gene. PB1-F2 is considered to play …

Elucidating the Role of Antigen-presenting Cells in the Immunopathogenesis of the Porcine Reproductive and Respiratory Syndrome Virus
… most economically devastating pathogens in the swine industry today. The PRRSV was discovered in the early 1990s in Europe and the United States, with strains being divided into Type 1 and Type 2 genotypes, respectively. Disease outcomes range from being asymptomatic to upwards of 100% mortality …

Virologic Factors Contributing to the Genetic Diversification of Influenza Viruses Circulating in North American Swine
… was to determine mechanisms of reassortment of swine influenza viruses and determine if certain reassortant gene combinations can drive evolution and host adaptation in the context of the triple reassortant internal gene (TRIG) cassette. The TRIG contains a unique combination of a human …

Phylogenetic approaches for quantifying the genotypic diversity of influenza viruses
… birds are thought to be the main reservoir for Influenza A viruses, hosting the largest burden of influenza diversity generated by high frequencies of co-infection and segment reassortment. The recently emerged avian influenza viruses that spilled-over into the human population were all produced …

The development of a novel vaccine against avian influenza H7N9 virus
Influenza A viruses (IAV) are classified into the Orthomyxoviridae family and are composed of segmented, negative-sense, single-stranded ribonucleic acid (ssRNA) genomes in an enveloped particle. IAV is capable of infecting a wide variety of species, including but not limited to humans, birds, …
