Histopathology, bacteriology and experimental transmission of cold-water vibriosis in Atlantic salmon Salmo salar

In Scotland, low level mortalities in farmed Atlantic salmon were associated with a bacterium which had properties generally associated wlth the genus Vibno, but which did not resemble any previously described species. In naturally infected fish extensive sloughing and necrosis of the gut mucosa, haemorrhaging, and an increase in perltoneal exudate were recorded. Similar lesions were produced i...

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 ...

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...

Comparative experimental transmission of cardiomyopathy syndrome (CMS) in Atlantic salmon Salmo salar.

Cardiomyopathy syndrome (CMS) has been recorded in wild and farmed Atlantic salmon Salmo salar. Characteristic heart lesions primarily involving the myocardium are reported in natural outbreaks with associated mortality. To date, no experimental trials have reproduced these lesions in the laboratory. The present study reports on the first successful experimental transmission of CMS in Atlantic ...
