Outbreak of viral haemorrhagic septicaemia (VHS) in seawater-farmed rainbow trout in Norway caused by VHS virus Genotype III.
We describe the finding of a novel viral haemorrhagic septicaemia virus (VHSV) Genotype III strain that caused disease of both a neurological and septicaemic nature in seawater-farmed rainbow trout Oncorhynchus mykiss in Storfjorden, Norway. In November 2007, an outbreak of VHS associated with slightly elevated mortality was confirmed at a seawater site rearing rainbow trout (90 to 440 g). With...
متن کاملIn vitro susceptibility of rainbow trout fin cells to viral haemorrhagic septicaemia virus
Cells isolated from rainbow trout fins Oncorhynchus mykiss, Walbaum were propagated and subcultured a s fibroblast-like. Viral haemorrhagic septicaemia virus (VHSV) replicated in the cultured fin cells as demonstrated by fin cell lysis, posihve immunofluorescence with polyclonal antiVHSV, and Increase in titre as measured by either infection of f ~ s h cell lines or by sandwich ELISA with anti-...
متن کاملVirulence of viral haemorrhagic septicaemia virus (VHSV) genotype III in rainbow trout.
In general, viral haemorrhagic septicaemia virus (VHSV) isolates from marine fish species in European waters (genotypes GIb, GII and GIII) are non- to low virulent in rainbow trout. However, a VHSV isolation was made in 2007 from a disease outbreak in sea farmed rainbow trout in Norway. The isolate, named NO-2007-50-385, was demonstrated to belong to GIII. This isolate has attracted attention t...
متن کاملCell-mediated cytotoxicity in rainbow trout, Oncorhynchus mykiss, infected with viral haemorrhagic septicaemia virus.
Mammalian cytotoxic T cells as part of the adaptive immune system recognize virus-infected target cells by binding of their T-cell receptors (TCR) to classical MHC class I molecules loaded with viral peptides. Our previous studies have shown that the allele of the single dominant polymorphic classical MHC class I locus Onmy-UBA is identical in the rainbow trout clone C25 and in the permanent ra...
متن کاملViral load of various tissues of rainbow trout challenged with viral haemorrhagic septicaemia virus at various stages of disease.
Market-sized rainbow trout Oncorhynchus mykiss were challenged by waterborne exposure to viral haemorrhagic septicaemia virus (VHSV isolate of genogroup Ia). Fish were sampled at 4 stages of infection (before onset of clinical signs, clinically affected fish, mortalities and survivors) and the viral load determined in (1) internal organs, (2) muscle tissue and (3) brain and gill tissue. Virus l...
