The incursion of the human pandemic influenza A virus H1N1 (2009) (H1N1 pdm) into pig populations and its ongoing co-circulation with endemic swine influenza viruses (SIVs) has yielded distinct human-porcine reassortant virus lineages. The haemagglutinin (HA) gene of H1N1 pdm was detected in 41 influenza virus-positive samples from seven swine herds in north-west Germany in 2011. Eight of these...
We studied anti-influenza cytotoxicity by bulk peripheral blood mononuclear leukocyte (PBL) cultures derived from older, chronically ill volunteers undergoing vaccination. Vaccinees received either cold-recombinant, live-attenuated influenza A/Korea/1/82 (H3N2) virus intranasally or inactivated monovalent influenza A/Taiwan/1/86 (H1N1) subvirion vaccine intramuscularly. PBL were collected pre- ...
Simple and rapid diagnosis of influenza is useful for making treatment decisions in the clinical setting. Although many influenza rapid diagnostic tests (IRDTs) are available for the detection of seasonal influenza virus infections, their sensitivity for other viruses, such as H5N1 viruses and the recently emerged swine origin pandemic (H1N1) 2009 virus, remains largely unknown. Here, we examin...
The global population has been exposed to the novel pandemic H1N1 influenza virus since mid March 2009, causing the expansion of respiratory illness around the world, including Thailand. To evaluate the antibody titers against human pandemic influenza (H1N1) in Thai people with influenza-like illness (ILI), 45 paired serum samples (acute and convalescent) were subjected to hemagglutination inhi...
BACKGROUND The 2009 swine-origin influenza virus (S-OIV) H1N1 pandemic has caused more than 18,000 deaths worldwide. Vaccines against the 2009 A/H1N1 influenza virus are useful for preventing infection and controlling the pandemic. The kinetics of the immune response following vaccination with the 2009 A/H1N1 influenza vaccine need further investigation. METHODOLOGY/PRINCIPAL FINDINGS 58 volu...
BACKGROUND One of the challenges of the recent pandemic (H1N1) 2009 influenza outbreak was to differentiate the virus from seasonal influenza when confronting clinical cases. The determination of the virus has implications on treatment choice, and obvious epidemiologic significance. OBJECTIVES We set out to apply a novel electrochemical device to samples derived from clinical cases of pandemi...
The novel H1N1 influenza virus that emerged in humans in Mexico in early 2009 and transmitted efficiently in the human population with global spread has been declared a pandemic strain. Here we review influenza infections in swine since 1918 and the introduction of different avian and human influenza virus genes into swine influenza viruses of North America and Eurasia. These introductions ofte...
Schaefer R., Zanella J.R.C., Brentano L., Vincent A.L., Ritterbusch G.A., Silveira S., Caron L. & Mores N. 2011. Isolation and characterization of a pandemic H1N1 influenza virus in pigs in Brazil. Pesquisa Veterinária Brasileira 31(9):761-767. Embrapa Swine and Poultry Research Center, BR153, Km110, Vila Tamanduá, Concórdia, SC 89700000, Brazil. E-mail: [email protected] Influenza A viru...
The recent pandemic caused by human influenza virus A(H1N1) 2009 contains ancestral gene segments from North American and Eurasian swine lineages as well as from avian and human influenza lineages. The emergence of this A(H1N1) 2009 poses a potential global threat for human health and the fact that it can infect other species, like pigs, favours a possible encounter with other influenza viruses...
The Norwegian pig population was considered free from influenza A virus infections until the first case of porcine pandemic influenza A (H1N1) 2009 virus infection in October 2009. Human to pig transmission of virus was suspected. Unusual lung lesions were observed in fattening pigs, with red, lobular, multifocal to coalescing consolidation, most frequently in the cranial, middle, and accessory...
