title: Epidemiology of inclusion body hepatitis in poultry in northern India from 1990 to 1994.
abstract: The epidemiology of inclusion body hepatitis (IBH) was studied in poultry in northern India, from April 1990 to March 1994, to evaluate the various factors responsible for causing and determining the severity of the disease. Broiler chicks and Japanese quail (Coturnix coturnix japonica) were the species examined. The factor observed to be most commonly associated with IBH was the presence of aflatoxins in the feed at higher than permissible levels, i.e. 20 parts per billion. Avian adenovirus-1 was isolated from the livers of affected birds. In the final year of the study, a number of outbreaks of IBH caused heavy mortalities among three to five-week-old broiler chicks, which displayed typical IBH lesions in addition to hydropericardium.
