Immune responses elicited in rainbow trout through the administration of infectious pancreatic necrosis virus-like particles

Isolation and Identification of the Infectious Haematopoietic Necrosis Virus (IHNV)-like Agent from Farmed Rainbow Trout (Oncorhynchus mykiss) from Iran

Effects of in vitro addition of infectious pancreatic necrosis virus (IPNV) on rainbow trout Oncorhynchus mykiss leucocyte responses.

Infectious pancreatic necrosis virus (IPNV) did not replicate in rainbow trout macrophages cultured in vitro, but a limited increase in viral titer was observed when total leucocytes were infected with the virus. Macrophages did not respond directly to IPNV, in that IPNV did not trigger the respiratory burst of these cells, even when the macrophages were previously stimulated. Supernatants were...

Detection of rainbow trout antibodies to infectious pancreatic necrosis virus by an immunoassay

An enzyme-linked immunosorbent assay (ELISA) for the detection of infectious pancreatic necrosis virus (IPNV) antibodies in rainbow trout Oncorhynchus mykjss was assessed. There was close agreement between the results of the ELISA and a neutralisation test for detecting lPNV antibody when fish sera were tested by both methods. The differences between the ELISA and virus neutralisation are most ...

Infectious pancreatic necrosis virus triggers antiviral immune response in rainbow trout red blood cells, despite not being infective

Some fish viruses, such as piscine orthoreovirus and infectious Background salmon anemia virus, target red blood cells (RBCs), replicate inside them and induce an immune response. However, the roles of RBCs in the context of infectious pancreatic necrosis virus (IPNV) infection have not been studied yet. : Ex vivo rainbow trout RBCs were obtained from peripheral blood, Methods Ficoll purified ...

Occurrence of the infectious Pancreatic necrosis virus in Rainbow trout (Oncorhynchus mykiss) farms in Hidalgo State, Mexico

During the first semester of 2002 the occurrence of the infectious pancreatic necrosis virus (IPNV) in rainbow trout (Oncorhynchus mykiss) farms was investigated in the state of Hidalgo, Mexico. A total of 25 out of 29 analysed farms were positive for IPNV; however only one farm had clinically diseased fish. The spread of IPNV in this state seems to be associated with the movement of trout eggs...
