Calisto, Rita; Sæbø, Eirik Færøy; Storesund, Julia Endresen; Øvreås, Lise; Herfindal, Lars; Lage, Olga M. (Peer reviewed; Journal article, 2019-01-07)There is a strong need to develop new drugs against many severe diseases. Therapy resistance is a major problem, for instance, in infectious diseases and cancer. Drug discovery has again turned to nature to search for ... -

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway
Giulietti, Lucilla; Levsen, Arne; Bao, Miguel; Karlsbakk, Egil Erlingsson; Storesund, Julia Endresen; Tung, Hai-Shan; Cipriani, Paolo (Journal article; Peer reviewed, 2024)Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. ... -

The importance of microbiota and terrestrial inflows in controlling seston C:N:P:O:Si:Ca:Mn:Mg:Fe:K:Na:Cl:S:Cu:Zn stoichiometry of a deep coastal fjord
Erga, Svein Rune; Heldal, Mikal; Prestegard, Siv Kristin; Norland, Svein; Tsagkaraki, Tatiana Margko; Storesund, Julia Endresen (Journal article; Peer reviewed, 2022)Comprehensive fjord-systems represent major extensions of the coastline and are therefore important transfer zones of materials from land to ocean. Despite increased terrestrial inflows to fjords due to climate changes, ... -
Linking bacterial community structure to advection and environmental impact along a coast-fjord gradient of the Sognefjord, western Norway
Storesund, Julia Endresen; Sandaa, Ruth-Anne; Thingstad, T. Frede; Asplin, Lars; Albretsen, Jon; Erga, Svein Rune (Peer reviewed; Journal article, 2017-12)Here we present novel data on bacterial assemblages along a coast-fjord gradient in the Sognefjord, the deepest (1308 m) and longest (205 km) ice-free fjord in the world. Data were collected on two cruises, one in November ... -
Long-term investigation of the ‘soft flesh’ condition in Northeast Atlantic mackerel induced by the myxosporean parasite Kudoa thyrsites (Cnidaria, Myxozoa): Temporal trends and new molecular epidemiological observations
