Microbial and pathological findings in farmed Atlantic salmon Salmo salar with proliferative gill inflammation.
Proliferative gill inflammation (PGI) is an important cause of loss in seawater-farmed Atlantic salmon in Norway. Several microbes have been associated with PGI, including the commonly but not exclusively observed inclusions (epitheliocysts) within the gill lamellae related to infection with 'Candidatus Piscichlamydia salmonis'. Atlantic salmon transferred in the spring of 2004 to 12 seawater f...
متن کاملIsolation and partial characterization of a novel paramyxovirus from the gills of diseased seawater-reared Atlantic salmon (Salmo salar L).
A formerly undescribed virus has been isolated from the gills of farmed Atlantic salmon post-smolts in Norway suffering from gill disease. Cytopathic effects appeared in RTgill-W1 cells 9 weeks post-inoculation with gill tissue material. Virus production continued for an extended period thereafter. Light and electron microscopic examination revealed inclusions and replication in the cytoplasm. ...
متن کاملA Novel Betaproteobacterial Agent of Gill Epitheliocystis in Seawater Farmed Atlantic Salmon (Salmo salar)
Epitheliocystis, a disease characterised by cytoplasmic bacterial inclusions (cysts) in the gill and less commonly skin epithelial cells, has been reported in many marine and freshwater fish species and may be associated with mortality. Previously, molecular and ultrastructural analyses have exclusively associated members of the Chlamydiae with such inclusions. Here we investigated a population...
متن کاملAtlantic 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 ...
متن کاملHistopathological study of gills in experimentally amoebic gill disease (AGD) infected Atlantic salmon, Salmo salar, L.
Amoebic gill disease (AGD) is the most important parasitic disease of Atlantic salmon industry inAustralia. Atlantic salmon (Salmo salar) experimentally infected with Neoparamoeba sp. apparently showedAGD gross signs on the gill and an amoebic-associated gill pathology. Physico-chemical factors of waterduring the experiment were monitored regularly and were approximately constant (temperature: ...
