Background: Aviadenoviruses affect birds, particularly chickens, ducks, geese, turkeys and pheasants, which have total 12 serotypes. Inclusion body hepatitis (IBH) caused by aviadenovirus was has been reported in many countries worldwide. The diseases was first reported from Assam in 2017. Although there is increasing reports of the occurrence of IBH-HPS in the broiler population of North Eastern India, but its prevalence at different geoclimatic condition and at various seasons have not been carried out. Under these circumstances, the present study was envisaged to analyse the seroprevalence status of Fowl adenovirus infection in some broiler rearing districts of Assam. Methods: For the present study, blood samples were collected from 12 different districts of Assam including all agroclimatic regions during the period from June, 2016 to May, 2017. Association of various factors like age, season and health status with the prevalence of the affected birds were also studied. Indirect ELISA was performed by using commercially available FAdV ELISA kit. The results obtained were analyzed by the Statistical Package for Social Sciences (SPSS) version 26.0.Result: A total of 460 serum samples were screened, of which 213 were found positive for FAdV antibodies with a sero-positivity of 46.38 per cent. FAdV antibodies were observed in all age grouped birds. Highest (64.28%) positivity was recorded in the birds of 4th week of age, followed by above 4th week (63.47%), 3rd week (32.03%), 2nd week (27.36%) and 1st week (10.0%). Health status-wise 68.97 percent sero-positivity was recorded in the affected flock, where as 32.51 percent in apparently healthy flock. Season-wise, highest (61.53%) sero-positivity was recorded in post monsoon season followed by monsoon (49.00%), winter (32.49%) and pre-monsoon (32.39%).

Commercial broiler flocks from a farm located in the State of São Paulo, Brazil, presented diarrhea, depression, increased mortality and poor weight gain. Upon post-mortem examination, classical signs of Inclusion Body Hepatitis/Hydropericardium Syndrome (IBH/HPS) were observed, including enlarged pale yellow-colored livers and straw-colored liquid in the pericardial sac. In addition, gross lesions were also observed in the kidneys, pancreas, thymus, intestines and gallbladder. Samples of these organs were analyzed by PCR for the detection of the hexon gene of the Fowl Adenovirus (FAdVs) Group I. The results were positive for both flocks (A and B) assayed by PCR. The macroscopic lesions associated with the detection of FAdV Group I by PCR in several of these affected organs allowed for the identification of IBH/HPS. In fact, this is the first report in Brazil of IBH/HPS in broilers, which identifies FAdVs group I as a causal agent of the disease. These findings may contribute to the worldwide epidemiology of the adenovirus-mediated hepatitis/hydropericardium syndrome.

AbstractIntroductionFowl adenovirus can cause important diseases in chickens such as inclusion body hepatitis, hepatitis hydropericardium syndrome, and gizzard erosion and ulceration. Inclusion body hepatitis has been regularly reported from many countries. This is the first case report from Turkey, describing an outbreak of inclusion body hepatitis in broiler farms due to fowl adenovirus-8b (FAdV-8b).Material and MethodsBroiler flocks with mortality about 10% were visited in Turkey, and necropsy was performed on dead birds. Samples were subjected to PCR assay to detect FAdV and other viral pathogens. After sequencing, phylogenetic analysis was performed and the nucleotide sequences of hexon genes were compared with the FAdV sequences data available in GenBank.ResultsClinical signs such as anorexia, depression, ruffled feathers, huddling, and greenish diarrhoea were observed. Mortality started at the 8th day of age and ranged from 10% to 14%. Necropsy showed severe hepatitis, jaundice, and pancreatitis. The main necropsy findings included a pale, enlarged, haemorrhagic, and friable liver along with swollen and haemorrhagic kidneys and spleen. PCR and sequence analysis revealed the presence of fowl adenovirus serotype 8b (FAdV-E).ConclusionThis is the first report on characterisation and the pathological lesions associated with FAdV in broilers in Turkey. Our findings suggest that FAdV strains could be an emerging pathogen in Turkish broilers and could actively contribute to hepatitis and immunosuppression.

We report the complete genome sequence of fowl adenovirus D (FAdV-D) strain JP/Tokushima/2010IBH, which was isolated from chickens with inclusion body hepatitis in Japan. This FAdV-D isolate was genetically highly similar to recent isolates from China, suggesting a common origin.
