From: Roux-Y Gastric Bypass and Sleeve Gastrectomy directly change gut microbiota composition independent of surgery type

Figure 1

Observed and estimated richness of gut microbiota at different time points during the bariatric surgery procedure. (A) Shannon diversity index estimated a decrease in bacterial richness at S2 and S3. (B) Rarefaction curves showed a reduction in bacterial richness at S2 and S3. (C) Principal component analysis (PCA) plot of similarity between the samples; each dot represents 1 sample, each color a different time point. S1. before surgery (red); S2. after 2 weeks of crash diet (orange); S3. 1 week after surgery (yellow); S4. 3 months after surgery (light blue); S5. 6 months after surgery (dark blue).
