In the present study the impact on gut microbiology and indigenous gut histology of Atlantic salmon ( Salmo salar L.) was investigated following feeding of a control and a prebiotic (EWOS prebiosal ® ) diet and ex vivo exposure to saline or the probiotic bacterium Carnobacterium divergen s. The results showed that ex vivo exposure of C. divergens at 10 8 CFU ml -1 did not cause cell damage to the intestine tract of Atlantic salmon. Furthermore, prior provision of dietary prebiotic elevated the ability of C. divergens to adhere to the epithelium or mucus layer in the proximal intestine, where culturable heterotrophic bacterial levels (which were identified as C. divergens ) were elevated by 234% compared to the control. This effect was not apparent in the distal intestine. The ability of isolated carnobac.. View More»
