The correlationship between the nine distinguished pathway and the 23 significantly differed genera indicated that Prevotella_9 (OTU_5) was negatively related with meiosis-yeast, alpha-linolenic acid metabolism, PPAR signaling pathway, adipocytokine signaling pathway, peroxisome, and amoebiasis, which was the opposite condition for Bacteroides (OTU_22) (p<0.05). Here, PPARA is linked to amebiasis.
