Molecular Characterization and Phylogenetic Analysis of Neuraminidase Gene in A/H1N1 Influenza Virus Isolates Circulating in Iran, 2014-2015.
Objectives: Influenza is one of the most important emerging and reemerging infectious diseases in the world. The aim of this study is molecular and phylogenetic analyses of the variations in circulating influenza A/H1N1 virus isolates during 2014-2015 in Iran and investigate on the drug resistance conditions in the related Iranian isolates. Material and Methods: Throat samples from Iranian pat...
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...
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 evaluation of M2 protein of Iranian avian influenza viruses of H9N2 subtype in order to find mutations of adamantane drug resistance
Background: The H9N2 subtype of influenza A viruses is considered to be widespread in poultry industry. Adamantane is a group of antiviral agents which is effective both in prevention and treatment of influenza A virus infections. These drugs inhibit M2 protein ion channel which has role on viral replication. OBJECTIVES: The main objective of this study is to evaluate M gene of avian influenza ...
متن کاملMolecular Surveillance of Avian Influenza in Bird Parks of Tehran, Iran
BACKGROUND: Avian influenza (AI) viruses have been isolated from a wide diversity of free-living avian species representing several orders. Since 1998, H9N2 AI outbreaks have been one of the major problems in Iranian poultry industry. In 2006, H5N1 was reported in swans in the north of Iran first , but until now there has been no official report from commercial flocks in Iran. OBJECTIVES: The...
