Characterization of Pseudoterranova ceticola (Nematoda: Anisakidae) larvae from meso/bathypelagic fishes off Macaronesia (NW Africa waters)
Bao, Miguel; Olsen, Kaja M.; Levsen, Arne; Cipriani, Paolo; Giulietti, Lucilla; Storesund, Julia Endresen; García-Seoane, Eva; Karlsbakk, Egil Erlingsson (Journal article; Peer reviewed, 2022)The genus Pseudoterranova includes parasite species of cetaceans and pinnipeds. The third stage larva (L3) of seal-infecting species occur in second intermediate or paratenic fish hosts mainly in neritic waters. This study ... -
Distribution of Kudoa thyrsites (Cnidaria, Myxozoa) myoliquefactive stages in Northeast Atlantic mackerel (Scomber scombrus) inferred from qPCR and histology
Giulietti, Lucilla; Johansen Nedberg, Heidi; Karlsbakk, Egil Erlingsson; Marathe, Nachiket Prakash; Storesund, Julia Endresen; Mæhle, Stig; Fiksdal, Ingrid Uglenes; Ghebretnsae, Dawit Berhe; Levsen, Arne (Journal article; Peer reviewed, 2022)Kudoa thyrsites is a myxosporean parasite (Cnidaria, Myxozoa) that infects the skeletal and cardiac muscle of Northeast Atlantic (NEA) mackerel (Scomber scombrus). Heavy infections are associated with post-mortem myoliquefaction ... -
Effect of Anisakis simplex (sl) larvae on the spoilage rate and shelf-life of fish mince products under laboratory conditions
Svanevik, Cecilie Smith; Lunestad, Bjørn Tore; Levsen, Arne (Peer reviewed; Journal article, 2014-12)Wild caught marine fish are commonly infected with anisakid nematodes lodging in the intestinal linings or in the fish muscle. One of the most commonly found nematode parasites in marine fish is Anisakis simplex. During ... -
Fish feed as source of potentially allergenic peptides from the fish parasite Anisakis simplex (s.l.)
Fæste, Christiane Kruse; Levsen, Arne; Lin, Aung Htun; Larsen, Natalie; Plassen, Christin; Moen, Anders; Do, Thien Van; Egaas, Eliann (Peer reviewed; Journal article, 2015-04)The carry-over of certain feed components into animal products can be of concern for human health. The safety assessment of chemical contaminants including natural toxins, agrochemicals, veterinary drugs, and environmental ... -
High prevalence of Ichthyophonus sp. infections in Northeast Atlantic mackerel (Scomber scombrus)
Storesund, Julia Endresen; Nylund, Caroline Da Silva; Karlsbakk, Egil Erlingsson; Giulietti, Lucilla; Bao, Miguel; Cipriani, Paolo; Levsen, Arne (Journal article; Peer reviewed, 2022) -
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
Giulietti, Lucilla; Karlsbakk, Egil Erlingsson; Cipriani, Paolo; Bao Dominguez, Miguel; Storesund, Julia Endresen; Marathe, Nachiket; Levsen, Arne (Journal article; Peer reviewed, 2022)Northeast Atlantic (NEA) mackerel (Scomber scombrus, Scombridae) represents an economically important target for the Norwegian pelagic fishing industry. Despite the commercial significance of NEA mackerel, little is known ... -
Microbiological assessment along the fish production chain of the Norwegian pelagic fisheries sector - Results from a spot sampling programme
Svanevik, Cecilie Smith; Roiha, Irja Sunde; Levsen, Arne; Lunestad, Bjørn Tore (Peer reviewed; Journal article, 2015-10)Microbes play an important role in the degradation of fish products, thus better knowledge of the microbiological conditions throughout the fish production chain may help to optimise product quality and resource utilisation. ... -
Molecular characterization of the myoliquefactive fish parasite kudoa mirabilis (Cnidaria, kudoidae) from se Indian Ocean and its phylogenetic relationship with the kudoa thyrsites species complex
Giulietti, Lucilla; Karlsbakk, Egil; Cipriani, Paolo; Shayo, Salome Daniel; Storesund, Julia Endresen; Levsen, Arne (Journal article; Peer reviewed, 2020)Myxosporean parasites of the genus Kudoa are fish parasites of great economic importance, as some species can affect the fish fillet quality by producing macroscopic cysts or generating post mortem myoliquefaction, commonly ... -
Resurrection of genus Phocanema Myers, 1959, as a genus independent from Pseudoterranova Mozgovoĭ, 1953, for nematode species (Anisakidae) parasitic in pinnipeds and cetaceans, respectively
Bao, Miguel; Giulietti, Lucilla; Levsen, Arne; Karlsbakk, Egil Erlingsson (Journal article; Peer reviewed, 2023)Species of the genus Pseudoterranova, infect kogiid cetaceans and pinnipeds. However, there is mounting molecular evidence that those from cetaceans and pinnipeds are not congeneric. Here, we provide further evidence of ...
