Figure 4.
Fecal microbial analysis. (A) There was no statistically significant difference in the richness (Chao1 index) between the baseline and after rifaximin treatment groups. (B) There was no statistically significant difference in the complexity (Shannon index) between the baseline and after rifaximin treatment groups. (C) Taxonomic composition of fecal bacterial communities in the genus level. The relative abundance of Veillonella was decreased after 4 weeks of treatment with rifaximin, while the other genera were unchanged.
