Genomic characterization of the virus causing infectious salmon anemia in Atlantic salmon (Salmo salar L.): an orthomyxo-like virus in a teleost.
The genome of infectious salmon anemia virus (ISAV), which infects farmed Atlantic salmon (Salmo salar L.), is characterized here. The virus has an RNA genome, as shown by using specific DNA virus metabolic inhibitors and radioactive in vivo labeling of ISAV nucleic acid. Electrophoresis of [14C]uridine-labeled ISAV RNA revealed that the ISAV genome is segmented. The genome consists of eight se...
متن کاملCloning and identification of the infectious salmon anaemia virus haemagglutinin.
Infectious salmon anaemia virus (ISAV) is an orthomyxo-like virus that causes serious disease in Atlantic salmon (Salmo salar). Like the orthomyxoviruses, ISAV has been shown to possess haemagglutinin (HA) activity. This study presents the cloning, expression and identification of the ISAV HA gene, which was isolated from a cDNA library by immunoscreening. The HA gene contained an ISAV-specific...
متن کاملDevelopment and characterization of two cell lines from gills of Atlantic salmon
Gill disease in Atlantic salmon, Salmo salar L., causes big losses in the salmon farming industry. Until now, tools to cultivate microorganisms causing gill disease and models to study the gill responses have been lacking. Here we describe the establishment and characterization of two cell lines from the gills of Atlantic salmon. Atlantic salmon gill cell ASG-10 consisted of cells staining for ...
متن کاملIsolation of infectious salmon anemia virus (ISAV) from Atlantic salmon in New Brunswick, Canada.
Infectious salmon anemia virus (ISAV) was isolated at a marine grow-out site in New Brunswick, Canada, from Atlantic salmon Salmo salar which experienced mortalities due to hemorrhagic kidney syndrome (HKS). Of 20 fish sampled in this study, 14 showed histologically various degrees of interstitial hemorrhaging, tubular epithelial degeneration and necrosis, and tubular casts in the posterior kid...
متن کاملIn vivo correlates of infectious salmon anemia virus pathogenesis in fish.
The phenotypic correlates of pathogenicity for Infectious salmon anemia virus (ISAV) in salmonid fishes have not been thoroughly studied to date. In this study, a comparison was made of 13 different strains of ISAV, isolated from different geographical regions between 1997 and 2004, for their infectivity in three fish species [Atlantic salmon (Salmo salar), coho salmon (Oncorhynchus kisutch) an...
