Atlantic salmon Salmo salar and ballan wrasse Labrus bergylta display different susceptibility to clonal strains of Paramoeba perurans
Dahle, Ole Martin Vik; Blindheim, Steffen H.; Nylund, Are; Karlsbakk, Egil; Breck, Olav; Glosvik, Henriette; Andersen, Linda (Journal article; Peer reviewed, 2020)Amoebic gill disease (AGD), caused by the marine amoeba Paramoeba perurans, is an important disease of farmed Atlantic salmon Salmo salar L. in Norway. The use of wrasse as cleaner fish in salmon net pens raises questions ... -
Characterization of ‘Candidatus Syngnamydia salmonis’ (Chlamydiales, Simkaniaceae), a bacterium associated with epitheliocystis in Atlantic salmon (Salmo salar L.)
Nylund, Stian; Steigen, Andreas; Karlsbakk, Egil; Plarre, Heidrun; Andersen, Linda; Karlsen, Marius; Watanabe, Kuninori; Nylund, Are (Peer reviewed; Journal article, 2015-01)Two Chlamydiales have previously been found to infect Atlantic salmon (Salmo salar L.), Candidatus Piscichlamydia salmonis and Candidatus Clavichlamydia salmonicola. Both develop intracellularly in cyst-like inclusions in ... -
Dying for change: A roadmap to refine the fish acute toxicity test after 40 years of applying a lethal endpoint
Katsiadaki, Ioanna; Ellis, Tim; Andersen, Linda; Antczak, Philipp; Blaker, Ellen; Burden, Natalie; Fisher, Tom; Green, Christopher; Labram, Briony; Pearson, Audrey; Petersen, Karina; Pickford, Dan; Ramsden, Chris; Rønneseth, Anita; Ryder, Kathy; Sacker, Dominic; Stevens, Chloe; Watanabe, Haruna; Yamamoto, Hiroshi; Sewell, Fiona; Hawkins, Penny; Rufli, Hans; Handy, Richard D.; Maynard, Samuel K.; Jacobs, Miriam (Journal article; Peer reviewed, 2021)The fish acute toxicity test (TG203; OECD, 2019) is frequently used and highly embedded in hazard and risk assessment globally. The test estimates the concentration of a chemical that kills 50% of the fish (LC50) over a ... -
Experimental challenge of Atlantic salmon Salmo salar using clones of Paramoeba perurans, P. pemaquidensis and Tetramitus sp.
Nylund, Are; Røed, Martin; Blindheim, Steffen H.; Trösse, Christiane; Andersen, Linda (Journal article; Peer reviewed, 2021)Salmon gill disease in Norway is in most cases associated with a range of different pathogens, stress and environmental factors. Paramoeba perurans and other amoebae have been isolated during such disease outbreaks. Other ... -
Growth characteristics and morphology of Paramoeba perurans from Atlantic salmon Salmo salar L. and ballan wrasse Labrus bergylta in Norway
Blindheim, Steffen Hageselle; Andersen, Linda; Trösse, Christiane; Karlsbakk, Egil Erlingsson; Nylund, Are (Journal article; Peer reviewed, 2023)Background Paramoeba perurans is the causative agent of amoebic gill disease (AGD) in Atlantic salmon Salmo salar L. and many other farmed marine fish species worldwide. The first cases of AGD in Norway were reported in ... -
Method for cryopreservation of Paramoeba perurans
Trösse, Christiane; Nylund, Are; Blindheim, Steffen H.; Andersen, Linda; Kindt, Mats Martin (Journal article; Peer reviewed, 2020-11-07)Paramoeba perurans causes amoebic gill disease (AGD), which is a major problem in aquaculture worldwide. The parasite can be cultured in vitro, but to this date, no method for long-term storage of the clones exists. In ... -
Net cleaning impacts Atlantic salmon gill health through microbiome dysbiosis
