Comparison of bacterial quantities in left and right colon biopsies and faeces

Figure 1 Quantities of bacterial groups detected on the mucosa and in faeces. The bacterial targets A: Akkermansia muciniphila; B: Bacteroidetes; C: Bifidobacterium spp.; D: Clostridium cluster IV; E: Clostridium cluster XIVab; F: Collinsella aerofaciens; G: Enterobacteriaceae; H: Faecalibacterium prausnitzii; I: Veillonella spp.; J: Eubacteria are represented with the three sample types side-by-side (biopsies from the right colon as white bars with pattern; biopsies from the left colon as grey bars; faecal samples with dark grey bars). The bacterial quantities between the two mucosal samples did not differ according to paired t-tests, whereas the faecal quantities of all analysed bacteria were significantly higher than those detected for either mucosal site (P < 0.05), except for Enterobacteriaceae. The error bars denote the 95% CI.
