Abstract

Eighty-one stool samples from Taiwanese were collected for analysis of the association between the gut flora and obesity. The supervised analysis showed that the most, abundant genera of bacteria in normal samples from people with a body mass index BMI 24 were Bacteroides 27.7%, Prevotella 19.4%, Escherichia 12%, Phascolarctobacterium 3.9%, and Eubacterium 3.5%. The most abundant genera of bacteria in case samples with a BMI 27 were Bacteroides 29%, Prevotella 21%, Escherichia 7.4%, Megamonas 5.1%, and Phascolarctobacterium 3.8%. A principal coordinate analysis PCoA demonstrated that normal samples were clustered more compactly than case samples. An unsupervised analysis demonstrated that bacterial communities in the gut were clustered into two main groups: N-like and OB-like groups. Remarkably, most normal samples 78% were clustered in the N-like group, and most case samples 81% were clustered in the OB-like group Fisher’s . The results showed that bacterial communities in the gut were highly associated with obesity. This is the first study in Taiwan to investigate the association between human gut flora and obesity, and the results provide new insights into the correlation of bacteria with the rising trend in obesity.
