Microbiota comparison between C. difficile negative and positive residents. a Mean cumulative relative abundance distribution for the major bacterial genera (>1 %) for C. difficile negative (N = 38 samples) and positive residents (N = 80 samples). b Changes in microbial genus populations between C. difficile negative and positive residents. Populations whom relative abundance is statistically different are expressed as mean relative abundance ± standard error of the mean (p < 0.05 according to multiple unpaired t-test with Benjamini-Hochberg False Discovery Rate). c Bacterial diversity (inverse Simpson biodiversity index), bacterial richness (Chao1 richness index) and bacterial evenness (Deduced from Simpson index). Bacterial diversity indexes are expressed as the mean value with standard deviation, from subsampled datasets. Statistical differences are represented by asterisks (p < 0.05 according to non parametric Mann–Whitney test) after Bonferroni corrections
