Fowl adenovirus (FAdV) is a member of the genus Aviadenovirus and causes a number of economically important poultry diseases. One of these diseases, inclusion body hepatitis (IBH), has a worldwide distribution and is characterised by acute mortality (5% - 20%) in production chickens. The disease was first described in the United States of America in 1963 and has also been reported in Canada, th...

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 sus...

Abstract Fowl adenovirus infections have a significant economic impact, especially in the production of broilers. It is considered leading cause three syndromes: adenoviral gizzard erosions and ulcerations, inclusion body hepatitis, hepatitis-hydropericardium syndrome. A critical feature this virus its immunosuppressive effect, via suppressing humoral cellular immunity. In study, we examined im...

In this study, we determined and genetically characterized three fowl adenoviruses isolated from chickens with inclusion body hepatitis (IBH) and hydropericardium syndrome (HPS) in China and assessed their pathogenicity. The full genome of HBQ12, BJH13 and JSJ13 was found to be 44,081, 43,966 and 43,756 nucleotides long, respectively. Sequence alignment and phylogenetic analysis revealed that s...

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...

The sequence of the celO gene from Clostridium thermocellum F7 was determined. The gene product, cellulase CelO (Ct-Cel5F), had a modular structure consisting of a carbohydrate-binding module of the CBM3 family and a catalytic domain of the glycosyl hydrolase family 5. The presence of the dockerin module indicated that the enzyme was a component of the cellulosome complex. The thermostable reco...
