These important histological alterations are coincident with
modifications in the intestinal microbiota. The PCR-DGGE patterns
analysis has shown that the dietary administration of inulin or
The inclusion of the prebiotic inulin produced a decrease in the
species richness, although the H0 index was not affected. The
cluster analyses of the PCR-DGGE patterns demonstrated that the
inclusion of inulin increased the similarity of these patterns. The
ability of inulin to alter intestinal microbiota has previously been
noted in Artic charr (S. alpinus) [60], although Mahious et al. [61]
did not described a clear effect of inulin on the intestinal bacterial
community of turbot (Psetta maxima).
