Evaluation of H9N2 avian influenza virus dissemination in various organs of experimentally infected broiler chickens using RT-PCR
Widespread occurrence of H9N2 low pathogenic avian influenza (LPAI) viruses in many Asian countriesduring the past decade has resulted in the need for evaluation of the pathogenesis of H9N2 virus infection. In this study, tissue tropism and dissemination of A/Chicken/Iran/772/1998(H9N2) virus throughout the body of broiler chickens were investigated. The clinical signs, gross lesions and antibo...
متن کاملSequence Analysis and Phylogenetic Profiling of the Nonstructural (NS) Genes of H9N2 Influenza A Viruses Isolated in Iran during 1998-2007
The earliest evidences on circulation of Avian Influenza (AI) virus on the Iranian poultry farms date back to 1998. Great economic losses through dramatic drop in egg production and high mortality rates are characteristically attributed to H9N2 AI virus. In the present work non-structural (NS) genes of 10 Iranian H9N2 chicken AI viruses collected during 1998-2007 were fully sequenced and subjec...
متن کاملDetection of Seasonal Influenza H1N1 and H3N2 Viruses using RT-PCR Assay during 2009 Flu Pandemic in Golestan Province
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...
متن کاملتغییرات ژنتیکی ویروس و فرار از سامانه ایمنی، چالشهای پیشرو علیه آنفلوآنزا: مقاله مروری
The spread of influenza viruses in multiple bird and mammalian species is a worldwide serious threat to human and animal populations' health and raise major concern for ongoing pandemic in humans. Direct transmission of the avian viruses which have sialic acid specific receptors similar to human influenza viruses are a warning to the emergence of a new mutant strain that is likely to share mole...
متن کاملFusion and sequence analysis of the influenza A (H9N2) virus M2e and C-terminal fragment of Mycobacterium tuberculosis HSP70 (H37Rv)
The present study was aimed to construct a fusion plasmid harboring the extracellular domain of the influenza A M2-protein (M2e), which was fused to the N-terminus of the truncated HSP70 (HSP70359–610) molecule as a new approach for future vaccine research against influenza A. The amplified fragments, M2e and HSP70359-610 genes, were gel-purified. The products were then single digested with Bam...
