The pathogenicity of different birnavirus strains to turbot was determined by challenge experiments. The reference strains of IPNV (Sp, Ab and VR-299) were not pathogenic for turbot (Scophthalmus maximus). The Norwegian serotype (N1) and two selected birnavirus strains isolated from turbot and related to the Ab serotype of IPNV (TB-306 and TB-390) were virulent to different degrees for turbot a...
conclusions taken together, these data reveal that cellular protease of chicken liver cells allows the replication of high yields of h9n2 virus in the absence of trypsin and also cell death in the infected cells is due to necrosis. results the degree of viability was significantly reduced in infected hepatoma cells. observations of caspase activation and cell dna laddering in infected cells wer...
Intraperitoneal injection of virulent infectious pancreatic necrosis virus (IPNV) into yearling brook trout Salvelinus fontinalis induced an asynlptomatic, chronic w u s infection that persisted for at least 76 wk post-lnlection (wpl) in spite of the production of a strong humoral immune response. At 8 wpi, 100 % of the fish in one of the injected groups were IPNV camers , as determined by orga...
Multiple virus infections have recently been observed during routine examination of salmonid fish.1) Infectious hematopoietic necrosis virus (IHNV) and infectious pan creatic necrosis virus (IPNV) are often isolated together or with other viruses, such as a herpes virus or a retro-like virus.1,2) In case of multiple virus infections, only the virus which replicates most efficiently will be dete...
