Isolation, identification and molecular characterization of Inclusion body hepatitis virus

چکیده
Inclusion body hepatitis caused by avian adenovirus with highly pathogenic strain lead to heavy mortality and unusual lesion like hydropericardium in commercial broilers. Samples were collected from an outbreak in 12000 broiler flock from Andhra Pradesh with sudden high mortality initiated from 32 days of age. Liver was enlarged and showed petechae. Hydropericardium was extensive. 10% liver suspension inoculated to SPF chicks produced mortality with hydropericardium and showed presence of intranuclear inclusions in the hepatocytes. Viral DNA extracted from infected liver processed for PCR produced an amplicon of 890 bp. Nucleotide sequence analysis using blast programme of NCBI showed 99% identity with fowl adenovirus.

Background and Aims: Inclusion body hepatitis (IBH) is one of the most important reemerging diseases in many countries with intensive poultry industries. In Iran, the etiological agent of IBH (fowl adenovirus) has not been yet confirmed. The aim of this study was the molecular detection and identification of fowl adenovirus involving IBH in chicken flocks in Iran. Materials and Methods: Polymer...
متن کاملMolecular identification of aviadenoviruses in broiler chickens suspected to inclusion body hepatitis in Golestan province, Iran
Background: Fowl adenoviruses (FAdVs) are distributed widely throughout the world, and domestic avian species of all ages are susceptible. Fowl aviadenoviruses (FAdVs) can be separated into 5 different species (A-E) with various genotypes and 12 serotypes. Some geno- or serotypes induce hepatitis-hydropericardium syndrome (HPS), inclusion body hepatitis (IBH), and adenoviral gizzard erosion (AG...
متن کاملIdentification of Aptamer-Binding Sites in Hepatitis C Virus Envelope Glycoprotein E2
Hepatitis C Virus (HCV) encodes two envelope glycoproteins, E1 and E2. Our previous work selected a specific aptamer ZE2, which could bind to E2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting HCV. In this study, the binding sites between E2 and aptamer ZE2 were further explored. E2 was truncated to 15...

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...
