Article Synopsis
  • A study investigates filamentous Gram-negative bacteria impacting salmon aquaculture, focusing on isolates from Atlantic salmon affected by mouthrot in British Columbia, Canada, where no genomes were previously available.
  • Researchers used ribosomal DNA sequencing and whole genome sequencing to analyze ten isolates, discovering four known species and two possibly new ones, alongside various potential virulence and antimicrobial resistance genes.
  • The findings highlight specific genes related to disease and resistance, offering valuable insights for future research and strategies in managing mouthrot disease in salmon aquaculture.

There is a limited understanding of the pathogenesis of tenacibaculosis in Atlantic salmon ( L.) and there are few reproducible exposure models for comparison. Atlantic salmon were exposed via bath to , , or and were then grouped with naïve cohabitants.

are frequently detected from fish with tenacibaculosis at aquaculture sites; however, information on the ecology of these bacteria is sparse. Quantitative-PCR assays were used to detect and at commercial Atlantic salmon () netpen sites throughout several tenacibaculosis outbreaks. and were identified in live fish, dead fish, other organisms associated with netpens, water samples and on inanimate substrates, which indicates a ubiquitous distribution around stocked netpen sites.

is a genus of gram negative, marine, filamentous bacteria, associated with the presence of disease (tenacibaculosis) at aquaculture sites worldwide; however, infections induced by this genus are poorly characterized. Documents regarding the genus and close relatives were compiled for a literature review, concentrating on ecology, identification, and impacts of potentially pathogenic species, with a focus on Atlantic salmon in Canada. species likely have a cosmopolitan distribution, but local distributions around aquaculture sites are unknown.
