*The DGGE analysis was performed by applying universal bacterial primers (UNIV) and specific primers for the lactic acid bacteria (LACT), Eubacterium rectale – Clostridium coccoides group (EREC), Clostridium leptum group (CLEPT), Bacteroides fragilis group (BFRA) and Bifidobacterium spp. (BIFI).

**Detection frequencies (% of samples positive) of the specified DGGE genotypes are presented. Statistical analysis: The Fisher's exact test based on band presence/absence data. P-values for the statistically significant differences are presented in parenthesis.
