Fig. 2From: Long-term effects on luminal and mucosal microbiota and commonly acquired taxa in faecal microbiota transplantation for recurrent Clostridium difficile infectionDonors’ microbiota and alterations in the patients’ faecal and mucosal microbiota before and after faecal microbiota transplantation (FMT) treatment. a The average microbial composition in faecal samples (see panel d for bacterial groups). Donors’ microbiota shown as average from all time points. b Principle component analysis (PCA) from genus level bacterial groups in faecal samples; donors’ samples in dark blue, patients’ pre-FMT samples coloured red and post-FMT samples coloured turquoise. c Microbial diversity in faecal samples measured from patients and donors (average from all time points), statistical significance from other time points indicated with an asterisk. d The average microbial composition in patients’ mucosal samples. e PCA from genus level bacterial groups in patients’ mucosal samples, pre-FMT samples coloured red (patients with one sample n = 13 and patient P3 with 2 samples, see Additional file 1: Table S1) and post-FMT samples (patient n = 11) coloured turquoise. f The fold change of genus level bacterial groups was significantly different in the pre- and post-FMT mucosal samples. d Phylum level taxonomyBack to article page
