Vaccine-associated systemic Rhodococcus erythropolis infection in farmed Atlantic salmon Salmo salar

Atlantic salmon – Salmo salar

Distribution Th e species’ range encompasses Europe, North America, and Green land (1) (Fig.1). Non-anadromous forms occur in Europe in a few land-locked locations in Norway and Sweden, and throughout the Neva/Lake Ladoga system and Karelia regions of Russia. In North America non-anadromous forms occurred throughout most of the species’ historical range, as far west as Lake Ontario, and remain ...

Estimation of direct costs associated with cataracts in farmed Atlantic salmon (Salmo salar)

A spreadsheet model that has been standardised for use across different livestock species and diseases, was utilised to estimate the direct costs of cataracts in farmed fish, using the Norwegian farmed salmon industry segment as an example. The data input for the model was obtained from previously published information and also from a small survey specifically carried out to obtain the addition...

Diseases of farmed Atlantic salmon Salmo salar associated with infections by the microsporidian Paranucleospora theridion.

The microsporidian Paranucleospora theridion was discovered in Atlantic salmon Salmo salar suffering from proliferative gill disease in a marine farm in western Norway in 2008. The parasite develops in cells of the reticuloendothelial system, cells important for normal immune function. The aim of this study was to see if P. theridion could play a part in some of the diseases with unclear causes...

Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar

There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains μ, δ and τ, respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, Atlantic salmon (Salmo salar) possess two highly similar Ig heavy chain gene complexes (A and B), comprising two μ genes, two δ genes, three intact τ genes and five τ pseu...
