Idiopathic intranuclear inclusion bodies in the renal tubular epithelia of Japanese quail (Coturnix coturnix japonica)

Abstract

We report idiopathic intranuclear inclusion bodies in the renal tubular epithelia of two cases of among the 960 Japanese quail (Coturnix coturnix japonica) in the course of the acute oral toxicity and dietary toxicity test. Basophilic inclusion bodies were seen only in the nuclei of renal tubular epithelia. We could not classify our case into any adenovirus infection by clinical signs and lesions. The inclusion bodies were only identified as adenovirus-like particles based upon the electronmicroscopical features.
