[Adenovirus-induced pneumonia in two guinea pigs]

Two cases of a rare virus-induced disease of Guinea pigs are described. The animals had died because of a pneumonia. Large intranuclear viral inclusion bodies could be demonstrated in the endothelial cells of the lungs. In the second case inclusion bodies could be found additionally in macrophages of the spleen and in macrophages, hepatocytes and endothelial cells of the liver. By means of electron microscopy the virus could be specified as adenovirus.
