Heavy and light chain homologs of ferritin are essential for blood-feeding and egg production of the ectoparasitic copepod Lepeophtheirus salmonis
Heggland, Erna Irene; Trösse, Christiane; Eichner, Christiane; Nilsen, Frank (Peer reviewed; Journal article, 2019)The salmon louse, Lepeophtheirus salmonis, is a hematophagous ectoparasite of salmonid fish. Due to its blood-feeding activity, the louse is exposed to great amounts of iron, which is an essential, yet potentially toxic ... -
Hematophagy in the salmon louse (Lepeophtheirus salmonis) : Characterization of genes and proteins involved in parasite blood-feeding
Heggland, Erna Irene (Doctoral thesis, 2020-02-13)The salmon louse (Lepeophtheirus salmonis) is an obligate, hematophagous ectoparasite infecting salmonid fish such as the Atlantic salmon (Salmo salar). The parasite is at present the number one threat to the Norwegian ... -
Host gill attachment causes blood-feeding by the salmon louse (Lepeophtheirus salmonis) chalimus larvae and alters parasite development and transcriptome
Heggland, Erna Irene; Dondrup, Michael; Nilsen, Frank; Eichner, Christiane (Journal article; Peer reviewed, 2020-05-06)Background: Blood-feeding is a common strategy among parasitizing arthropods, including the ectoparasitic salmon louse (Lepeophtheirus salmonis), feeding off its salmon host’s skin and blood. Blood is rich in nutrients, ... -
The transcriptomic response of adult salmon lice (Lepeophtheirus salmonis) to reduced salinity
Borchel, Andreas; Heggland, Erna Irene; Nilsen, Frank (Journal article; Peer reviewed, 2021)Salmon lice (Lepeophtheirus salmonis) are marine parasitic copepods living on salmonids and are challenging for salmon aquaculture. One of several treatment methods is the application of freshwater to the fish which can ... -
Without a pinch of salt: effect of low salinity on eggs and nauplii of the salmon louse (Lepeophtheirus salmonis)
Borchel, Andreas; Heggland, Erna Irene; Nilsen, Frank (Journal article; Peer reviewed, 2023)The salmon louse is an economically important parasite on Atlantic salmon and poses a major threat to aquaculture. Several treatment methods have lost their effect due to resistance development in the lice. A rather new ...
