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...

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...
