Infectious pancreatic necrosis virus (IPNV) is a nonenveloped virus, with a double stranded (dsRNA) genome. The capsid is of an icosahedral structure 60 nm in diameter. IPNV is found in both freshwater and seawater worldwide. IPNV has been isolated from a wide diversity of aquatic organisms, mainly fish, but also mollusks and crustaceous. In salmonid fish it causes a highly contagiuos disease called IPN (infectious pancreatic necrosis), which mainly affect the acinarcells of the pancreas. After replication it spreads through the blood to other organs, and may be persistent in the host for years without causing death. The main problem to the host is weightloss due to necrosis in the enzym secreting pancreatic tissue.
