Phylogenetic Analysis of H1N1 2009 Influenza Virus
نویسندگان
چکیده
Since April of 2009, the novel swine-origin influenza A (H1N1) virus (S-OIV) has rapidly spread across the globe. The World Health Organization declared the outbreak a global pandemic in June. The new S-OIV has a unique genome composition and contains genes derived from avian, human, and swine influenza viruses. It has been reported that the new S-OIV may have emerged from the reassortment of previous reported triple-reassortant swine influenza viruses and Eurasian avian-like swine lineages. Human infections with swine influenza A viruses had been reported in the past. Although the infections occurred sporadically, some cases were fatal.

Background: Influenza virus is a major infectious pathogen of the respiratory system causing a high degree of morbidity and mortality annually. The worldwide vaccines are decided and produced annually by World Health Organization and licensed companies based on the samples collected from all over the world. The aim of this study was to determine phylogenecity and heterogenecity of the circulati...

متن کاملAntigenic Variation of the Haemagglutinin Gene of the Influenza A (H1N1) pdm09 Virus Circulating in Shiraz, February-April 2013
Background: A new pandemic influenza A (H1N1) emerged in April 2009, causing considerable morbidity and mortality. Since mutations in the haemagglutinin (HA) may influence the antigenicity and pathogenicity of the virus, continued epidemiological and molecular characterization for the effective control of pandemic flu and developing of more appropriate vaccine is crucial. Objective: To monitor ...
متن کاملMolecular and Phylogenetic Analysis and Protein Structural modeling of NS Gene of Human Influenza A Virus Subtype H1N1 Circulating in Iran 2015 & 2017
Abstract Background: The NS (non-structural) genomic segment of influenza A virus expresses two proteins (NS1 and NS2) which are responsible for the virulence and pathogenicity of virus. In this study we investigate the characterization and variability of the NS gene recovered from H1N1 influenza viruses isolated from Iranian patients during the 2017 seasonal outbreak and from high...

Abstract Background and Objective: The emergence of a novel H1N1influenza A virus of animal origin with transmissibility from human to human poses pandemic concern. Current subtypes of Seasonal influenza A viruses spread in human are influenza A H1N1 influenza A H3N2 and influenza type B viruses. The aim of this study was to determine current strains of the H3N2 and new H1N1 subtypes of influe...
