ABSTRACT Infectious pancreatic necrosis (IPN) is an acute contagious systemic disease affecting several fish species and a critical disease in the salmonid fish farming industry. Here, we report the complete genome sequence of IPN virus (IPNV) RNA segments A and B, isolated from a farmed brook trout in Pennsylvania.

We investigated the susceptibility of trouts of different species and origins to infectious pancreatic necrosis virus (IPNV) and the pathogenicity of three strains of IPNV for brook trout (Salvelinus fontinalis) of various origins and lake trout (Salvelinus namaycush) of a single origin. Fish were inoculated by immersion in water containing 105 PFU of virus/mL for 6 h. Susceptibility to IPNV infection was assessed by counting dead fish over a period of 21 d after infection and on histological lesions in the pancreas, kidney, and intestine of the infected fish. Different species of trouts had different susceptibility to IPNV strain 3865. Brook trout had the highest mortality followed by rainbow trout (Salmo gairdneri), whereas the least mortality occurred in lake trout. Brook trout from Crowford, Nebraska, were more than twice as susceptible as the same species from Baldwin Mills, Quebec. Rainbow trout also varied in susceptibility as a result of origin. Virus isolate 3B, originally isolated from chain pickerel (Esox niger), was less virulent than isolates 4495 or 3865 (both from trout). Hatcheries that use water from sources containing pickerel may increase their chances of IPN infection.Key words: trout species, infectious pancreatic necrosis virus, resistance

Increased Susceptibility

Studies were conducted to determine the etiology of an epizootic disease occurring in fry and yearling brook trout (Salvelinus fontinalis); clinical signs, experimental infection, and pathological lesions suggested infectious pancreatic necrosis. Electron microscopy and physicochemical characteristics were used to identify the virus isolated from sick trout as IPN virus. The isolates showed only partial antigenic similarity to the reference strain IPN VR299. Increased susceptibility to IPN virus was observed in one genetic line of trout.

Pancreatic Necrosis Virus

The presence of infectious pancreatic necrosis (IPN) virus in brook (Salvelinus fontinalis) and rainbow (Salmo gairdneri) trout was identified and further investigated. A high incidence of virus was found by virological examination of kidney tissue from yearling and older trout. By comparison, brook trout had a much higher incidence of virus than rainbow trout.The virus was isolated most frequently from the kidneys of both species of trout. These findings indicate that the examinations of peritoneal washes and feces is not adequate for the detection of IPN carrier fish.
