Molecular characterization of non-structural gene of H9N2 subtype of avian influenza viruses isolated from broiler chickens in Iran
BACKGROUND: The H9N2 subtype of avian influenzaviruses (AIVs) have spread in Asia and Middle East countriesand have become a serious threat to poultry industry in Iran.OBJECTIVES:Characterization of genes of H9N2 subtype involvingin pathogenicity and diagnosis are crucial in control of avianinfluenza outbreaks. The Nonstructural (NS) gene and its proteinproducts (NS1 & NS2) are important as dia...
متن کاملFiber gene based molecular and biological characterization of hydropericardium-hepatitis syndrome associated avian adenoviruses
This study was designed to perform biological and molecular characterization of avian adenoviruses (AAVs) recovered from suspected cases of hydropericardium-hepatitis syndrome (HHS) in commercial poultry. Initially the samples were screened by Agar Gel Precipitation Test (AGPT) for the presence of AAVs followed by its confirmation and typing through polymerase chain reaction (PCR) focusing on a...
متن کاملAntigenic and genetic characterization of an avian poxvirus isolated from an endangered Hawaiian goose (Branta sandvicensis).
An avian poxvirus from cutaneous lesions in a Hawaiian goose (Branta sandvicensis) was characterized in this study. The virus was isolated by inoculation onto the chorioallantoic membranes (CAMs) of developing chicken embryos. Cytoplasmic inclusion bodies were observed on histopathological examination of CAM lesions. Western blotting analysis using polyclonal antiserum against fowl poxvirus (FW...
متن کاملMolecular detection and phylogenetic analysis of Avipoxvirus strains isolated from different bird species
The polymerase chain reaction (PCR) was used to amplify a 578 bp fragment of the poxvirus 4b core protein. Avipoxvirus (APV) specific DNA was detected in all 10 different isolates (each of which had been isolated from an epidemic) isolated from chicken; canary and mynah were collected from Tehran province. Sequencing was performed for 2 isolates as representative and the nucleotide sequence sho...
متن کاملMolecular characterization of avian adenoviruses in Iranian broiler flocks
This study was conducted to molecularly detect avian adenoviruses in broiler flocks showing liver lesions and respiratory syndrome in northeast Iran. In total, 60 tissue samples were collected from broiler farms with liver lesions, respiratory syndrome and also from clinically healthy flocks. Six samples were positive; however, three samples were selected for molecular studies. PCR products wer...
