Biotyping reveals loss of motility in two distinct Yersinia ruckeri lineages exclusive to Norwegian aquaculture
Riborg, Andreas Ekroll; Colquhoun, Duncan John; Gulla, Snorre (Journal article; Peer reviewed, 2022)Non-motile strains of Yersinia ruckeri, known as Y. ruckeri biotype 2, now dominate amongst clinical isolates retrieved from rainbow trout internationally. Due to an acute increase in the number of yersiniosis cases in ... -
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 ... -
Pan-genome survey of the fish pathogen Yersinia ruckeri links accessory- and amplified genes to virulence
Riborg, Andreas Ekroll; Gulla, Snorre; Fiskebeck, Eve Marie Louise Zeyl; Ryder, David; Verner-Jeffreys, David W.; Colquhoun, Duncan John; Welch, Timothy J. (Journal article; Peer reviewed, 2023)While both virulent and putatively avirulent Yersinia ruckeri strains exist in aquaculture environments, the relationship between the distribution of virulence-associated factors and de facto pathogenicity in fish remains ... -
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 ...
