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 ... -
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 ...
