It is caused by infectious pancreatic necrosis virus, which is a member of the Birnaviridae family.

IPNV disease was first described in salmonid fingerlings in a Canadian hatchery back in 1940 causing a very severe infection of the gut and the condition was referred to as a catarrhal enteritis. However the actual virus was not isolated until 1960 by Ken Wolf a virologist working in the USA. Infectious pancreatic necrosis virus (IPNV) is a Birnavirus that infects salmonid fish. The infection is usually mortal for fish under six months of age, while older fish become carriers, usually without any signs of infection, and will spread the virus to other susceptible fish and to their offspring. IPNV är ett ikosaederformat virus utan hölje vars arvsmassa består av två dubbelsträngade RNA-segment. IPNV tillhör virusfamiljen Birnaviridae, där namnet syftar på några av virusens kännetecken: bi- står både för de två RNA-segmenten och att RNAt är dubbelsträngat, medan -rna betecknar att arvsmassan består av just RNA. Methods Virus isolation and cell cultures. For growth and titration of IPNV from sampled tissues, the RTG2 cell line, from Viral RNA extraction and reverse-transcription (RT).

In both cases, survivors could become life-long carriers.22 In carriers approaching sexual maturity, variable levels of virus are found in The virus causing the typical signs of the IPN disease in salmonids, named infectious pancreatic necrosis virus (IPNV), has also been isolated from other fish species either suffering related diseases (then named IPNV-like virus) or asymptomatic; the general term aquabirnavirus is used to encompass all these viruses. The interplay between infectious pancreatic necrosis virus (IPNV) and the IFN system: IFN signaling is inhibited by IPNV infection.

The production of virus may increase under stress, and carriers can shed the virus and infect surrounding fish [11].

IPNV is represented by multiple strains with markedly different virulence. Comparison of isolates reveals hyper variable regions (HVR), which are presumably associated with pathogenicity. A total of 25 infectious pancreatic necrosis virus (IPNV) isolates were obtained, mainly from rainbow trout (Oncorhynchus mykiss). The molecular evolution of these Chinese IPNV isolates and the previously reported Chinese IPNV strains ChRtm213 and WZ2016 was analyzed, based on their VP2 gene coding region sequences (CDS). Virus antigen was detected in infected fry during and immediately after an epizootic, but although IPNV-carrier fish could be detected by the ELISA technique, the sensitivity of detection was not as great as that of isolation of the infectious virus in cell culture. A non‐destructive procedure was utilized to determine the infectious pancreatic necrosis virus (IPNV) status of an apparently healthy turbot broodstock.

IPNV is represented by multiple strains with markedly different virulence. Infectious pancreatic necrosis virus (IPNV) is an economically relevant pathogen of farmed Atlantic salmon (Salmo salar Linnaeus 1758) and rainbow trout (Oncorhynchus mykiss Walbaum 1792). The aquatic virus (Birnaviridae) has a bi-segmented double-stranded RNA genome of about six kilobases (kb).
