Eighteen broiler chickens affected spontaneously with inclusion body hepatitiswere studied histopathologically. Fatty degeneration and formation of intranuclear inclusion bodies in the hepatic cells were characteristic of this disease, as has been pointed outby previous workers. Various types were noticed in the inclusions. They were dividedroughly into two types, eosinophilic and basophilic, on the basis of stainability. Inclusionsof the former type were found in cells showing fatty degeneration and generally numerousthroughout the liver in all the birds examined, whereas those of the latter type were fewand found in cells hardly affected.Lesions of nephrosis, pancytopenia in the bone marrow, and atrophic changes in thebursa of Fabricius were consistently observed in the birds examined. It was emphasizedthat should be attention paid to these lesions, especially those in the bursa of Fabricius,in this disease, in addition to the hepatic changes.Two concurrent diseases, chronic respiratory disease and bacterial (mainly Escherichiacoli) infection, occurred in many cases. It was apparent that the latter complicated thecondition.
