Infectious equine arteritis virus See Equine arteritis virus

Infectious hematopoietic necrosis virus (IHNV) The type species of the genus Novirhabdovirus. Causes necrosis of hematopoietic tissues of spleen and anterior kidney in trout and salmon in North America, Europe, Korea, Taiwan, Japan and mainland China. Occurs as epidemic disease in fish hatcheries. The fish do not feed and often have a dark red subdermal lesion dorsally located at the back of the head. Replicates in fat head minnow cells or other fish cell lines with CPE. Studies in rainbow trout in fish hatcheries in Idaho show that there is wide genetic diversity amongst IHNV populations. Synonyms: chinook salmon virus; Oregon sockeye disease virus.
