Equine infectious anemia

This is an acute or chronic disease in horse. Before the world war II, about 9,000 horses were annually affected by this disease. However, all horses with virus infection were killed according to the Domestic Animal Infectious Diseases Control Law, resulting in no occurrence in Japan. Since the causative virus is very close to human AIDS virus, equine infectious anemia is considered to be an important disease model of AIDS. Many specimens are stored in this museum.

The liver lesion of congestive liver is called nutmeg liver because its cut surface resembles that of nutmeg. Nutmeg liver is observed in diseases such as equine infectious anemia.
