Fig 3. Quantification of fecal bacteria species before kidney transplantation.

A, B: Quantification of Lactobacilli in fecal samples collected before kidney transplantation. The proportion of patients harboring Lactobacilli in their feces before KT tended to be higher in NODAT patients and in initially diabetic patients than in controls (A; p = 0.08 by X² test). When initially diabetic and NODAT patients were grouped together, they more frequently harbored Lactobacilli in their feces than controls (B; p = 0.03 by X² test). C: Relative abundance of Faecalibacterium prausnitzii out of the total bacteria in the feces of transplanted patients collected before KT. Initially diabetic patients had a lower proportion of F. prausnitzii than controls. NODAT harbored an intermediate relative abundance of F. prausnitzii in their feces. D: Relative abundance of Clostridium leptum out of the total bacteria in the feces of transplanted patients collected before KT. Bars at the top of graphs indicate significant differences; dotted bars at the top of the graph indicate trends (p≤0.08); A, B: X² test. C, D: One-way ANOVA.
