Symbionts from the microbial flora may be seen as "expansion packs" as they provide an accessory genome to their hosts. Thereby, they confer additional functions such as treatment of otherwise undigestible metabolites and improved disease resistance. I am particularly interested in the latter aspect.
FishProbio: Efficient and sustaining alternative strategy to prevent and treat two major opportunistic diseases in salmonids, columnaris and furonculosis.
SORDAC-MAPAQ, Coll. S. Charette (IBIS).
Under inadequate conditions, however, the pathogen undergoes a shift in virulence as a response to the destabilisation of the host microbial flora. Currently available methods to treat furunculosis have been pushed to their limits, as they either favour antibiotic resistance or induce harmful adverse effects to the farmed fish. Endogenous probiotics are a promising alternative, since they are innocuous to the fish itself, to the environment and to human consumers. In this study, we use in vitro antagonism screening assays and next-generation sequencing to unravel efficient probiotic candidates from the brook charr against A. salmonicida.
