Influenza virus A subtype H1N1 is inhibited by methylated β-lactoglobulin

Journal of Dairy Research, 2010
Addition of methylated β-lactoglobulin (Met-BLG) in the medium of MDCK cell lines infected with influenza virus subtype H1N1 reduced hemagglutination activity (HA) in a concentration dependent manner. Antiviral activity of Met-BLG depended on its concentration, viral load, and duration of infection. Using 17 μg/ml of Met-BLG inhibited 50% of HA of H1N1

Efficacy of a high-growth reassortant H1N1 influenza virus vaccine against the classical swine H1N1 subtype influenza virus in mice and pigs

Archives of Virology, 2014
Swine influenza (SI) is an acute, highly contagious respiratory disease caused by swine influenza A viruses (SwIVs), and it poses a potential global threat to human health. Classical H1N1 (cH1N1) SwIVs are still circulating and remain the predominant subtype in the swine population in China.

Emergence of an Eurasian avian-like swine influenza A (H1N1) virus from mink in China.

Veterinary Microbiology, 2020
We evaluated the phenotype and genotype of a fatal influenza/canine distemper virus coinfection found in farmed mink in China. We identified a novel subtype H1N1 influenza virus strain from the lungs of infected mink designated A/Mink/Shandong/1121/2017 (

Epidemiological and virological characterization of influenza A virus subtype H1N1 at tertiary-care hospital, Ahmedabad

International Journal of Medical Science and Public Health, 2016
Background: In April 2009, a new strain of influenza virus, A H1N1, started to spread in various parts of the world, and the first case was reported on May 16, 2009.[1] The associated morbidity and mortality have made it a major health burden. In this study, we have investigated samples of patients with suspected influenza-like illnesses (ILIs ...

Transmissibility and severity of influenza virus by subtype.

Infection, Genetics and Evolution, 2018
The characteristics of influenza might vary depending on the disease subtype. This review includes previous studies on the transmissibility and severity of influenza and summarizes them by subtype.

Rapid identification of neuraminidase inhibitor resistance mutations in seasonal influenza virus A(H1N1), A(H1N1)2009, and A(H3N2) subtypes by melting point analysis

European Journal of Clinical Microbiology & Infectious Diseases, 2011
The high mutation rate of influenza virus, combined with the increasing worldwide use of influenza virus-specific drugs, allows the selection of viruses that are resistant to the currently available antiviral medications. Therefore, reliable tests for the rapid detection of drug-resistant influenza virus strains are required.

Protection against a European H1N2 swine influenza virus in pigs previously infected with H1N1 and/or H3N2 subtypes

Vaccine, 2003
A novel swine influenza virus, H1N2, circulates in European swine populations together with H1N1 and H3N2 viruses. This study examines whether post-infection immunity to H1N1 and/or H3N2 viruses provides cross-protection against H1N2 infection. Pigs (n=51) were inoculated intranasally with either Sw/Belgium/1/98 (H1N1) or Sw/Flanders/1/98 (H3N2), or ...

A structure-free digital microfluidic platform for detection of influenza a virus by using magnetic beads and electromagnetic forces.

Lab on a Chip, 2020
H1N1, a subtype of influenza A virus, has emerged as a global threat in the past decades. Due to its highly infectious nature, an accurate and rapid detection assay is urgently required.

[Evolution of the hemagglutinin gene of influenza A virus H1N1-subtype (1977-1983].

Molekuliarnaia genetika, mikrobiologiia i virusologiia, 1987
A scheme for evolutionary interrelations of the H1-subunits of influenza hemagglutinin genes is proposed for the natural variants of influenza A virus of the H1N1-subtype. It is based on experimental data obtained by the authors and those reported in the literature.

Amplification of the entire genome of influenza A virus H1N1 and H3N2 subtypes by reverse-transcription polymerase chain reaction

Journal of Virological Methods, 2006
This study describes the development of a simple RT-PCR method to amplify the whole genome of the influenza A virus based on the amplification of full-length gene segments. Primers were designed based on the conserved regions of both the 5'-end and the 3'-end of each gene segment.
