Characterization of natural killer cells in healthy goats (capra aegagrus hircus)
Jørgensen, Cathinka Celine (Student paper, others, 2021)NK cells are essential cells of the innate immune system characterized by their ability to spontaneously eliminate virus-infected cells, tumor cells and all cells that are missing evidence of self. In addition to their ... -
Consequences of Haemorrhagic Smolt Syndrome (HSS) for the Immune Status of Atlantic salmon (Salmo salar L.) (Case Study)
Krasnov, Aleksei; Sommerset, Ingunn; Søfteland, Tina; Afanasyev, Sergey; Boysen, Preben; Lund, Hege (Peer reviewed; Journal article, 2020)Haemorrhagic smolt syndrome (HSS) is a disorder of unknown aetiology causing losses in the fresh water phase of Atlantic salmon farming. Normally, the mortality is limited and symptoms disappear upon seawater exposure. In ... -
Detection of antibodies in Atlantic salmon using a bead-based multiplexed immunoassay
Teige, Lena Hammerlund (PhD Thesis;2020:01, Doctoral thesis, 2020)Viral diseases are among of the main challenges in aquaculture in Norway today. Heart- and skeletal muscle inflammation, caused by Piscine orthoreovirus (PRV), and pancreas disease (PD), caused by Salmonid alphavirus (SAV), ... -
