Correlations between Genus Oscillospira sp. abundance difference (stenotic site vs. non-stenotic site) and the degree of intestinal fibrosis. Patients with great and small Oscillospira sp. abundance differences were presented respectively. (A): Representative illustration showed the measurement of the normalized MT ratio of the affected bowel wall. Tissues with high MT ratios (such as skeletal muscle) appear yellow-red, while tissues with low MT ratios (such as subcutaneous fat) are dark blue. Normalized MT ratio of bowel wall was measured as MT ratios of the bowel wall (delineated by Inline graphic)/MT ratios of muscle (delineated by Inline graphic); (B): Spearman’s rank correlation analysis between Oscillospira sp. abundance difference and normalized MT ratio of bowel wall; (C). Representative intestinal histopathological characteristics of stenotic and non-stenotic sites in the same patient. ↔ indicated space volume of muscularis propria layer; indicated increased collagen deposition in submucosa and muscularis propria layers. (D): Spearman’s rank correlation analysis between Oscillospira sp. abundance difference and fibrosis score and space volume expansion score.
