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...
متن کاملInfectious 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...
متن کاملComparative 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...
متن کاملRainbow Trout, Oncorhynchus mykiss
Rainbow trout are classified as Oncorhynchus mykiss, and as such belong to the same genus as Pacific salmon, and to the family Salmonidae, which includes Atlantic salmon (Salmo salar), various trout (Salvelinus sp.), Arctic char (Salvelinus alpinus), Arctic grayling (Thymallus arcticus) and whitefish (Coregonus sp.). Rainbow trout are native to areas around the North Pacific Ocean, from souther...
متن کاملContinuous exposure to infectious pancreatic necrosis virus during early life stages of rainbow trout, Oncorhynchus mykiss (Walbaum).
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...
