Genetic and phylogenetic analysis of the ribonucleoprotein complex genes of H9N2 avian influenza viruses isolated from commercial poultry in Iran
BACKGROUND: The H9N2 subtype of avian influenzaviruses (AIVs) has been isolated in multiple avian species inmany European, Asian, African and American countries. Sincethe first outbreak of H9N2 virus in Iran in 1998, this virus haswidely circulated throughout the country, resulting in majoreconomic losses in chicken flocks. Several amino acids in thevirus ribonucleoprotein (RNP) complex includi...
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 کاملNucleoprotein (NP) Gene Based Phylogenetic Analysis of Iranian H9N2 Avian Influenza Isolates during 1998-2011
Background and Aims: Avian Influenza (AI) H9N2 subtype was first reported to infect turkeys in the United States in 1966 and has been panzootic in Eurasia. In Iran, the H9N2 virus was first isolated from broiler chickens in 1998 in Ghazvin province and it is the most prevalent subtype of influenza virus in poultry industry in Iran at the present time. Materials and Methods: In this study, we se...
متن کاملIdentification and characterization of H2N3 avian influenza virus from backyard poultry and comparison with novel H2N3 swine influenza virus.
In early 2007, H2N3 influenza virus was isolated from a duck and a chicken in two separate poultry flocks in Ohio. Since the same subtype influenza virus with hemagglutinin (H) and neuraminidase (N) genes of avian lineage was also identified in a swine herd in Missouri in 2006, the objective of this study was to characterize and compare the genetic, antigenic, and biologic properties of the avi...
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...
