Biogeography of the fish pathogen Aeromonas salmonicida inferred by vapA genotyping
Gulla, Snorre; Bayliss, Sion; Björnsdóttir, Bryndís; Dalsgaard, Inger; Haenen, Olga; Jansson, Eva; McCarthy, Una; Scholz, Felix; Vercauteren, Maaike; Verner-Jeffreys, David; Welch, Tim; Wiklund, Tom; Colquhoun, Duncan John (Peer reviewed; Journal article, 2019-04-12)A recently described typing system based on sequence variation in the virulence array protein (vapA) gene, encoding the A-layer surface protein array, allows unambiguous subtyping of Aeromonas salmonicida. In the present ... -
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 ... -
Multi-locus variable-number tandem-repeat analysis of the fish-pathogenic bacterium Yersinia ruckeri by multiplex PCR and capillary electrophoresis
Gulla, Snorre; Mohammad, Saima; Colquhoun, Duncan John (Peer reviewed; Journal article, 2019-06-17)Yersinia ruckeri is an important pathogen of farmed salmonids worldwide, but simple tools suitable for epizootiological investigations (infection tracing, etc.) of this bacterium have been lacking. A Multi-Locus Variable-number ... -
Multilocus sequence analysis reveals different lineages of Pseudomonas anguilliseptica associated with disease in farmed lumpfish (Cyclopterus lumpus L.)
Mjølnerød, Even Bysveen; Nilsen, Hanne Katrine; Gulla, Snorre; Riborg, Andreas Ekroll; Bottolfsen, Kirsten; Wiklund, Tom; Christiansen, Debes; Romalde López, Jesús Ángel; Scholz, Felix; Colquhoun, Duncan John (Journal article; Peer reviewed, 2021)The bacterium Pseudomonas anguilliseptica has in recent years emerged as a serious threat to production of lumpfish in Norway. Little is known about the population structure of this bacterium despite its association with ... -
Multilocus variable-number tandem-repeat analysis of Yersinia ruckeri confirms the existence of host specificity, geographic endemism, and anthropogenic dissemination of virulent clones
Gulla, Snorre; Barnes, Andrew C.; Welch, Timothy J.; Romalde, Jesús L.; Ryder, David; Ormsby, Michael J.; Carson, Jeremy; Lagesen, Karin; Verner-Jeffreys, David W.; Davies, Robert L.; Colquhoun, Duncan John (Peer reviewed; Journal article, 2018-08)A multilocus variable-number tandem-repeat analysis (MLVA) assay was developed for epizootiological study of the internationally significant fish pathogen Yersinia ruckeri, which causes yersiniosis in salmonids. The assay ... -
Tenacibaculosis in Norwegian Atlantic salmon (Salmo salar) cage-farmed in cold sea water is primarily associated with Tenacibaculum finnmarkense genomovar finnmarkense
Spilsberg, Bjørn; Nilsen, Hanne Katrine; Tavornpanich, Saraya; Gulla, Snorre; Lagesen, Karin; Jansen, Mona Dverdal; Colquhoun, Duncan John; Olsen, Anne Berit (Journal article; Peer reviewed, 2022)Skin conditions associated with Tenacibaculum spp. constitute a significant threat to the health and welfare of sea-farmed Atlantic salmon (Salmo salar L.) in Norway. Fifteen presumptive tenacibaculosis outbreaks distributed ... -
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 ...
