The culturable intestinal microbiota of triploid and diploid juvenile Atlantic salmon (Salmo salar)-a comparison of composition and drug resistance Leon Cantas 1,2* † , Thomas WK Fraser 3* † , Per Gunnar Fjelldal 4, Ian Mayer 3 and Henning Sørum 1 Background: With the increased use of ploidy manipulation in aquaculture and fisheries management this investigation aimed to determine whether triploidy influences culturable intestinal microbiota composition and bacterial drug resistance in Atlantic salmon (Salmo salar). The results could provide answers to some of the physiological differences observed between triploid and diploid fish, especially in terms of fish health. Results: No ploidy effect was observed in the bacterial species isolated, however, triploids were found to contain a significant increase in total gut microbiota levels, with increases in Pseudomonas spp., Pectobacterium carotovorum
