Identification of the bifidobacterial DGGE band positions by sequencing and the incidence of the bands in secretor (14) and non-secretor samples (57).

AThe similarity of the best Blast hit for a cultured strain is shown in parentheses, in cases where an uncultured bacterium was the best hit. Detailed data for the identification of each position is shown in table S1. B Only the band positions that were detected at least in 10 % of the samples are shown.** Significant differences: Band positions 26.6%, 17.70% and 63.7% were more frequently detected in secretor than non-secretor samples (Fisher's exact test, p
