Still the blood feeding copepod parasite, Lepeophtheirus salmonis, remains the major challenge for ... -
Genotyping tool for salmonid gill pox virus (SGPV) obtained from farmed and wild Atlantic salmon (Salmo salar)
Nylund, Are; Macintyre, Thomas Kloster-Jensen; Mohammadi, Faezeh; Lagadec, Erwan; Plarre, Heidrun (Journal article; Peer reviewed, 2023)Poxviruses are common viruses found in vertebrate species. In 2006, the first poxvirus associated with salmon, salmonid gill poxvirus (SGPV), was identified during an outbreak of gill disease at a smolt production site in ... -
Host associated genotypes in the family Branchiomonaceae with proposal of Ca. Branchiomonas mykissicola n. sp. from rainbow trout (Oncorhynchus mykiss)

Identification of housekeeping genes of Candidatus Branchiomonas cysticola associated with epitheliocystis in Atlantic salmon (Salmo salar L.)
Mjølnerød, Even Bysveen; Srivastava, Aashish; Moore, Lindsey; Plarre, Heidrun; Nylund, Are (Journal article; Peer reviewed, 2022)Candidatus Branchiomonas cysticola is an intracellular, gram-negative Betaproteobacteria causing epitheliocystis in Atlantic Salmon (Salmo salar L.). The bacterium has not been genetically characterized at the intraspecific ... -
Infection dynamics and tissue tropism of Parvicapsula pseudobranchicola (Myxozoa: Myxosporea) in farmed Atlantic salmon (Salmo salar)
Nylund, Are; Hansen, Haakon; Brevik, Øyvind Jakobsen; Hustoft, Håvard; Markussen, Turhan; Plarre, Heidrun; Karlsbakk, Egil (Peer reviewed; Journal article, 2018-01-06)Background The myxosporean parasite Parvicapsula pseudobranchicola commonly infects farmed Atlantic salmon in northern Norway. Heavy infections are associated with pseudobranch lesions, runting and mortality in the salmon ... -
Infectious salmon anaemia virus (ISAV): Evolution, genotyping, reservoirs and transmission
Plarre, Heidrun (Doctoral thesis, 2012-06-01)The first officially registered outbreak of infectious salmon anaemia (ISA) started in Norway in November 1984 (Thorud and Djupvik, 1988). It was a chronically proceeding disease among Atlantic salmon (Salmo salar) parr ... -
