Severe CDV-infected ependymal cells. A Normal ependymal cells appear like columnar cells (up arrow) with microvilli on their free surface. HE staining, Bar = 20 μm. B There are some eosinophilic inclusions (up arrow) in the cytoplasm and nucleus of ependymal cells. HE staining, Bar = 20 μm. C CDV antigen intense positive reaction (up arrow) in ependymal cells with inclusions. sABC staining, Bar = 20 μm. D Many apoptotic cells (up arrow) are found among ependymal cells. TUNEL staining, Bar = 20 μm
