Figure 4From: Reductions in intestinal Clostridiales precede the development of nosocomial Clostridium difficile infectionIntestinal bacterial taxa exhibiting significant differences in abundance between Clostridium difficile infection (CDI) cases and control subjects. The scatter plots show log-transformed 16S sequence counts for the corresponding bacterial (A) phylum or (B- D) family in cases (n = 25) versus controls (n = 25). Results are presented for both V1-V3 and V3-V5 sequence sets. Patients with the lowest degree of intestinal biodiversity (n = 6; all of these patients are cases) are shown with open circles. Horizontal lines represent the median and interquartile range. P values were determined by logistic regression.Back to article page
