چکیده

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%), Huancavelica (0.23%). These results showed epidemiology that, until 2019, was absent country. Likewise, it represents need implement prevention control measures against reduce risk dissemination free IPNV. Finally, improving sanitary management reduces its economic productive impact on

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...

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...
