Intraperitoneal injection of virulent infectious pancreatic necrosis virus (IPNV) into yearling brook trout Salvelinus fontinalis induced an asynlptomatic, chronic w u s infection that persisted for at least 76 wk post-lnlection (wpl) in spite of the production of a strong humoral immune response. At 8 wpi, 100 % of the fish in one of the injected groups were IPNV camers , as determined by orga...

Integrated multitrophic aquaculture (IMTA) reduces the environmental impacts of commercial aquaculture systems by combining the cultivation of fed species with extractive species. Shellfish play a critical role in IMTA systems by filter-feeding particulate-bound organic nutrients. As bioaccumulating organisms, shellfish may also increase disease risk on farms by serving as reservoirs for import...

Infectious pancreatic necrosis virus (IPNV) is a major viral pathogen of salmonid fish and causes serious economic losses to salmonid aquaculture. Previously, we demonstrated that the IPNV capsid protein, VP2, expressed in yeast self-assembles into subviral particles (SVPs) and injection of these IPNV rVP2 SVPs into rainbow trout elicits an immune response. Immunized fish had reduced viral load...

Infectious pancreatic necrosis (IPN) is a contagious viral disease of fish that causes economic losses in aquaculture worldwide. In Finland, IPN virus (IPNV) has been isolated since 1987 from adult fish showing no signs of clinical disease at fish farms located in the coastal areas of the Baltic Sea. The inland area of Finland, however, remained free of IPN until 2012, when fish on several rain...

Infectious hematopoietic necrosis virus (IHNV) and infectious pancreatic necrosis virus (IPNV) are important pathogens in rainbow trout aquaculture. Detection of these viruses in Croatia initiated investigation of their genetic relatedness to the worldwide IHNV and IPNV isolates. For this purpose, determination of nucleotide sequences of G and NV genes for IHNV and VP2/NS region for IPNV was pe...

Wild marine fish caught from a sea loch on the West Coast of Scotland were tested for infectious pancreatic necrosis virus (IPNV). One pool of 10 hake was found to be IPNV positive from 449 fish tested. This is believed to be the first isolation of IPNV made from hake caught in northern European waters. This was the only positive pool obtained from the study, illustrating a low prevalence of IP...

The infectious pancreatic necrosis virus (IPNV) is a highly pathogenic that affects the aquaculture of rainbow trout (Oncorhynchus mykiss) and can cause mortality rates exceed 90% in juvenile stage. This study aims to know distribution frequency IPNV presentation production farms seven main producing states species Peru. Prevalence values have been identified Cusco (4.05%), Puno (3.81%), Huanca...

Some fish viruses, such as piscine orthoreovirus and infectious Background: salmon anemia virus, target red blood cells (RBCs), highly replicate inside them and induce an immune response. However, the implications of RBCs in the context of birnavirus infection (i.e, infectious pancreatic necrosis virus (IPNV)) have not yet been studied. trout RBCs were obtained from peripheral blood, ficoll Met...

The double-stranded RNA-activated protein kinase R (PKR) is a Type I interferon (IFN) stimulated gene that has important biological and immunological functions. In viral infections, in general, PKR inhibits or promotes viral replication, but PKR-IPNV interaction has not been previously studied. We investigated the involvement of PKR during infectious pancreatic necrosis virus (IPNV) infection u...

Rainbow trout, Oncorhynchus mykiss (Walbaum), were exposed continuously to infectious pancreatic necrosis virus (IPNV) at 0, 10(1), 10(3) or 10(5) plaque forming units (pfu) L(-1) of water to estimate the effects of chronic IPNV exposure on early life stages. Fish density averaged 35 fish L(-1) (low density) or 140 fish L(-1) (high density), and the tank flow rate was 250 mL(-1) min. Virus expo...
