Figure 1 Bacterial diversity indicated as richness (No of bands) and diversity indices, obtained from single strand conformational polymorphism profiles of pouchitis patients in remission before randomisation (after treatment with antibiotics), after placebo (no therapy), and after VSL#3. For each group, the mean (SD) number of bands are shown. Bacterial diversity of the probiotic group was significantly higher compared with the starting value (p = 0.02). Weighted diversity scores (SD) showed the same tendency.
