Moreover, to further clarify the interaction between oral microbes and inflammatory markers in IBD, this study measured the levels of white blood cell (WBC), C-reactive protein (CRP), fecal calprotectin (FC), and erythrocyte sedimentation rate (ESR) which correlate with IBD, then correlation analysis and redundancy analysis was carried out, and the results demonstrated a positive correlation between SR1 and FC and showed that TM7 positively correlated with ESR, FC, and CRP [61]. The gene discussed is CRP; the disease is irritable bowel syndrome.
