From 2010 to 2013 in Japan, we isolated 11 swine influenza viruses (SIVs) from pigs showing respiratory symptoms. Sequence and phylogenetic analyses showed that 6 H1N1 viruses originated from the pandemic (H1N1) 2009 (pdm 09) virus and the other 5 viruses were reassortants between SIVs and pdm 09 viruses, representing 4 genotypes. Two H1N2 viruses contained H1 and N2 genes originated from Japan...
Since the beginning of January 2008 sporadic cases of infections in humans caused by influenza A (H1N1) virusresistant to available anti-influenza drugs have been reported worldwide [1,2]. The World Health Organization (WHO) in its report published on 18 March 2009 indicated that during weeks 1-4 (28 December 08-24 January 09), the level of overall influenza activity in the world increased. Dur...
In 2015, a novel influenza A(H1N1) virus was isolated from a boy in China who had severe pneumonia. The virus was a genetic reassortant of Eurasian avian-like influenza A(H1N1) (EA-H1N1) virus. The hemagglutinin, neuraminidase, and matrix genes of the reassortant virus were highly similar to genes in EA-H1N1 swine influenza viruses, the polybasic 1 and 2, polymerase acidic, and nucleoprotein ge...
background: the preventive measures against h1n1 influenza are vitally important. the aim of the present study was to assess the knowledge, attitude and performance of academic hospital staff about h1n1 influenza. methods: this study was carried out on ali-ebne-abiltaleb hospital staff in rafsanjan, iran. the data gathering tool was a researcher made questionnaire comprised of 38 questions on d...
The 2009 H1N1 swine flu is the first influenza pandemic in decades. The crystal structure of the hemagglutinin from the A/California/04/2009 H1N1 virus shows that its antigenic structure, particularly within the Sa antigenic site, is extremely similar to those of human H1N1 viruses circulating early in the 20th century. The cocrystal structure of the 1918 hemagglutinin with 2D1, an antibody fro...
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...
زمینه و هدف: در سالهای اخیر ویروس آنفلوانزا باعث عفونتهای متوسط تا شدید با میزان پراکندگی وسیع در سرتاسر دنیا شده است. بر این اساس، واکسن آنفلوانزایی که تنها یک دوز آن محافظت ایجاد نماید هنوز در دسترس نیست. بنابراین، تهیه یک واکسن عمومی و فراگیر بر اساس ذرات شبه ویروسی غیرتکثیری ایدهال میباشد. در تحقیق حاضر یکی از سازههای مولکولی برای ساخت این ذرات مد نظر قرار گرفته است. مواد و روشها: در ...
Background: Pandemic flu had at least two waves in Iran. Knowing how many of the general population were already exposed to this infection has a major impact on na-tional preventive measures. As of December 30, 2009, a total of 3672 confirmed cases of human infection with a novel Influenza A (2009 H1N1) virus had been reported in Iran with 140 deaths. Objective: In this study we aim to measure,...
Subtype H1N1 influenza A virus (IAV) that caused a pandemic in 2009, called A(H1N1)pdm09, has been circulating as seasonal IAV among humans, escaping from herd immunity through amino acid substitutions hemagglutinin (HA). Additionally, position 162 of HA A(H1N1)pdm09 evolved to be N-linked glycosylated by 2017. Here the effect glycosylation at was examined comparing ratio nonsynonymous diversit...
introduction: this study aimed to evaluate the clinical profile and outcomes of adult patients screened and diagnosed with h1n1 influenza infection at a tertiary care hospital in india. materials and methods: this retrospective study was conducted on all adult patients suspected of h1n1 influenza admitted at a teaching hospital during the epidemic period of january-march 2015. patients were sc...
