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...

Fowl adenoviruses (FAdV), detected during routine diagnostic investigations from 38 countries (5 continents) over a decade, were partially sequenced and grouped by phylogenetic analysis. The partial polymerase gene nucleotide sequences of the 365 fowl adenovirus isolates resulted in following species distribution: 11% FAdV-A; 3% FAdV-B; 2% FAdV-C; 34% FAdV-D; 50% FAdV-E. Noticeably, only 79 str...

avian adenovirus was isolated from naturally infected birds during 1990 to 2003 in the vicinity ofkarachi, pakistan. the virus is known to cause hydro-pericardium syndrome (hps) in poultry. the mortalitywas recorded 20-50% in commercial broilers. fifty field samples were collected; however, six samples wereselected for molecular studies. these isolates were grown and characterized by cell cultu...

Acute pulmonary edema, splenomegaly, and ascites were observed in a disease outbreak in adult white and pearl guinea fowl. The clinical history and gross and microscopic lesions resembled those described for marble spleen disease of pheasants and avian adenovirus group II splenomegaly of chickens. A small number of intranuclear inclusion bodies were found in liver, spleen, and lung sections of ...

Studies of hybridization between fowl adenovirus type 1 (chicken embryo lethal orphan virus) DNA and human adenovirus type 2 DNA revealed two short but distinct regions which cross-hybridized under stringent conditions. One of the homologous regions was located between map positions 18.1 and 19.3 and did not correspond to any gene recognized so far. The second region mapped in the hexon gene be...

Fowl adenovirus (FAdV) has caused significant losses in chicken flocks throughout China in recent years. However, the current understanding of the genetic and pathogenic characteristics of the FAdV epidemic in southwestern China remains poorly understood. In this study, a total of 22 strains were isolated from liver samples of diseased chickens from farms in southwestern China. Phylogenetic ana...

Until now, the only published ovine adenovirus DNA sequence was the complete genome of ovine adenovirus isolate 287 (OAV287) which, compared to other mammalian adenoviruses, possesses strikingly unique genomic organisation and should properly be classified into a new adenovirus genus. The protease gene sequence of ovine adenovirus type 3 (OAdV-3) was determined and analysed. The results of phyl...

We report here the complete genome sequence of virulent fowl adenovirus serotype 4 strain HB1510, isolated from a diseased chicken with hydropericardium-hepatitis syndrome in Hubei, China, in 2015. The viral genome is 43,721 bp long, and sequence analysis showed an 11-amino-acid deletion in open reading frame 29 (ORF29).
