Antibacterial treatment of lumpfish (Cyclopterus lumpus) experimentally challenged with Vibrio anguillarum, atypical Aeromonas salmonicida and Pasteurella atlantica
Kverme, Karen Obrestad; Kallekleiv, Marielle; Larsen, Kristina; Rønneseth, Anita; Wergeland, Heidrun I.; Samuelsen, Ole B.; Haugland, Gyri T. (Journal article; Peer reviewed, 2021)Lumpfish is a novel farmed species used as cleaner fish for the removal of lice from farmed salmon. As often with new, farmed species, there are challenges with bacterial infections. The frequency of prescription of ... -
Antibiotic uptake by cultured Atlantic cod leucocytes and effect on intracellular Francisella noatunensis subsp. noatunensis replication
Kaldestad, Marte Albriktsen; Haugland, Gyri Teien; Rønneseth, Anita; Wergeland, Heidrun Inger; Samuelsen, Ole Bent (Peer reviewed; Journal article, 2014-02-04)The granuloma disease caused by Francisella noatunensis subsp. noatunensis in farmed Atlantic cod has not been successfully treated by use of antibacterials, even when antibacterial resistance testing indicates a sufficient ... -
Dying for change: A roadmap to refine the fish acute toxicity test after 40 years of applying a lethal endpoint
Katsiadaki, Ioanna; Ellis, Tim; Andersen, Linda; Antczak, Philipp; Blaker, Ellen; Burden, Natalie; Fisher, Tom; Green, Christopher; Labram, Briony; Pearson, Audrey; Petersen, Karina; Pickford, Dan; Ramsden, Chris; Rønneseth, Anita; Ryder, Kathy; Sacker, Dominic; Stevens, Chloe; Watanabe, Haruna; Yamamoto, Hiroshi; Sewell, Fiona; Hawkins, Penny; Rufli, Hans; Handy, Richard D.; Maynard, Samuel K.; Jacobs, Miriam (Journal article; Peer reviewed, 2021)The fish acute toxicity test (TG203; OECD, 2019) is frequently used and highly embedded in hazard and risk assessment globally. The test estimates the concentration of a chemical that kills 50% of the fish (LC50) over a ... -
Genomic analysis of pasteurella atlantica provides insight on its virulence factors and phylogeny and highlights the potential of reverse vaccinology in aquaculture
Ellul, Rebecca Marie; Kalatzis, Panos G.; Frantzen, Cyril Alexander; Haugland, Gyri Teien; Gulla, Snorre; Colquhoun, Duncan John; Middelboe, Mathias; Wergeland, Heidrun Inger; Rønneseth, Anita (Journal article; Peer reviewed, 2021)Pasteurellosis in farmed lumpsuckers, Cyclopterus lumpus, has emerged as a serious disease in Norwegian aquaculture in recent years. Genomic characterization of the causative agent is essential in understanding the biology ... -
Neutrophils in Atlantic salmon (Salmo salar L.) are MHC class II+ and secret IL-12p40 upon bacterial exposure
Haugland, Gyri Teien; Rønneseth, Anita; Gundersen, Lene; Lunde, Harald Sæbø; Nordland, Kaja; Wergeland, Heidrun Inger (Journal article; Peer reviewed, 2022)Antigen-presentation via major histocompatibility complex (MHC) to T cells is the key event to initiate adaptive immune responses. In teleosts, as in mammals, the main types of professional antigen-presenting cells (APCs) ... -
Pasteurella spp. Infections in Atlantic salmon and lumpsucker
Sandlund, Nina; Rønneseth, Anita; Ellul, Rebecca Marie; Nylund, Stian; Sandlund, Liv (Journal article; Peer reviewed, 2021)The use of cleaner fish as a delousing method in Norwegian salmonid aquaculture has increased tremendously over the last few years. This has led to the emergence of a new large industry of farming lumpsuckers (Cyclopterus ... -
qPCR screening for Yersinia ruckeri clonal complex 1 against a background of putatively avirulent strains in Norwegian aquaculture
Riborg, Andreas Ekroll; Gulla, Snorre; Strand, David; Wiik-Nielsen, Jannicke; Rønneseth, Anita; Welch, Timothy J.; Spilsberg, Bjørn; Colquhoun, Duncan John (Journal article; Peer reviewed, 2022)Although a number of genetically diverse Yersinia ruckeri strains are present in Norwegian aquaculture environments, most if not all outbreaks of yersiniosis in Atlantic salmon in Norway are associated with a single specific ... -
Vibrio tapetis from wrasse used for ectoparasite bio-control in salmon farming: Phylogenetic analysis and serotyping
Gulla, Snorre; Rønneseth, Anita; Sørum, Henning; Vågnes, Øyvind Brune; Balboa, Sabela; Romalde, Jesús L.; Colquhoun, Duncan John (Peer reviewed; Journal article, 2017-08-09)So-called ‘cleaner fish’, including various wrasse (Labridae) species, have become increasingly popular in Norwegian salmon farming in recent years for biocontrol of the salmon louse Lepeophtheirus salmonis. Cleaner fish ...
