The histological changes observed in an outbreak of this disease were acute haemorrhagic enteritis, degeneration of lymphatic tissue, proliferation of reticuloendothelial cells all over the body, and formation of intranuclear inclusion bodies in these cells. By electron microscopy, viral particles showing a crystalline array were found in the nuclei of reticuloendothelial cells. Viral particles which had electron-dense nucleoids and a naked hexagonal shape were about 80 nm in average diameter. The ultrastructural features of those inclusion bodies were identical with those of avian adenovirus.
