Characterization of an infectious pancreatic necrosis virus from rainbow trout fry (Onhorhynchus mykiss) in West Ukraine

First isolation and identification of the Infectious Pancreatic Necrosis (IPN) virus from rainbow trout Onchorhynchus mykiss fingerlings farmed in Greece

During February 2000, two trout farms, situated in NW Greece, reported unusually high losses of hatchery reared rainbow trout fry and fingerlings. Live fish and chilled samples of diseased whole fish were delivered to a veterinary laboratory in Athens for diagnostic investigation. Infections with the fungus Ichthyophonus hoferi as well as the Gram negative bacterium Aeromonas hydrophila were di...

Mother to fry, successful transfer of immunity against infectious haematopoietic necrosis virus infection in rainbow trout.

We have tested whether immunity can be transferred from a mother fish to its fry. Rainbow trout mother fish were inoculated against infectious haematopoietic necrosis virus (IHNV) by intraperitoneal injection of a fragment of the IHNV glycoprotein spanning amino acids 31 to 310. This protein fragment was obtained by isolating the specific cDNA from Japanese IHNV strain HV7601 and expressing it ...

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

Infectious pancreatic necrosis in a recirculating rainbow trout (Oncorhynchus mykiss) culture system

During October 2009, a suspected outbreak of infectious pancreatic necrosis, with typical signs and high mortality, was observed in cultured rainbow trout (Oncorhynchus mykiss) fry (mean weight of 9 g) in a recirculating system in Fars Province, Iran. Tissue samples, including pyloric caeca as well as pancreatic tissues, liver, kidney, and spleen, were aseptically collected from 20 aff ected mo...

Comparative pathogenesis of three strains of infectious hematopoietic necrosis virus in rainbow trout Oncorhynchus mykiss

Three strains of infectious hematopoietic necrosis virus (IHNV) were compared for their pathogenicity to alevin rainbow trout Oncorhynchus n~ykiss by waterborne exposure of the trout to approximately equal concentrations of each virus strain The Idaho strain of IHNV (Type 2) was the most virulent and induced a 62 % mortality over a 10 d period at water temperatures of 10°C. In contrast, strains...
