INCLUSION BODY HEPATITIS
Fig. 1. Cross-section of the liver, 25-day-old broiler chicken. Multiple basophilic intranuclear inclusion bodies on the background of severe degenerative necrobiotic parenchymal lesions. H/E, Bar = 25 µm.
Fig. 2. The basophilic inclusion bodies are usually big and fill tightly the space around the nuclear membrane (arrow – b). H/E, Bar = 10 µm.
Fig. 3. Eosinophilic inclusion bodies are encountered significantly less frequently, have a round or irregular shape and are surrounded by a light halo (arrow – e). H/E, Bar = 10 µm.
Fig. 4. Although very rarely, along the liver intranuclear inclusion bodies (arrow – a), perivascular mononuclear proliferates (arrow – b) could also be seen. H/E, Bar = 25 µm.
