Virulence 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 کاملMolecular epidemiology of viral haemorrhagic septicaemia virus (VHSV) in British Columbia, Canada, reveals transmission from wild to farmed fish.
Viral haemorrhagic septicaemia virus (VHSV) is a fish pathogen found throughout the Northern Hemisphere and is capable of infecting and causing mortality in numerous marine and freshwater hosts. In the coastal waters of British Columbia, Canada, the virus has been detected for 20 yr with many occurrences of mass mortalities among populations of Pacific herring Clupea pallasii (Valenciennes) and...
متن کاملOutbreak 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 کاملDevelopment of a monoclonal antibody against viral haemorrhagic septicaemia virus (VHSV) genotype IVa.
The viral haemorrhagic septicaemia virus (VHSV) comprises 4 major genotypes and a number of subtypes with, in most cases, distinct geographical distribution. A quick and simple detection method that can discriminate the different genotypes is desirable for a quick and more efficient prevention of the spread of genotypes to new geographical areas. A monoclonal antibody (MAb) against VHSV genotyp...
متن کاملFish Rhabdoviruses Viral Haemorrhagic Septicaemia Virus (vhsv) and Perch Rhabdovirus (prv): Study of Viral Strains and the Disease Epidemiology in Finland
Viral haemorrhagic septicaemia virus (VHSV) was diagnosed after clinical symptoms for the first time in 2000 from four rainbow trout Oncorhynchus mykiss (Walbaum) farms in Åland and Pyhtää in Finland. Phylogenetic analysis based on the full-length VHSV glycoprotein (G) and nonvirion (NV) genes of the Finnish VHSV isolates in 2000–2004 revealed that all isolates are closely related and grouped i...
