Abstract:

The intestinal microbiota, acting as an important “Microbial Organ” in the human body, is related to a diverse
variety of physiological functions including immunity, nutrition and metabolism. This review provides an overview of the
origin and development as well as recent progress on the intestinal microbiota in humans, and insights into the association
between the intestinal microbiota and the pathogenesis of bowel diseases, obesity, diabetes and other common illnesses. We
hope that this paper will contribute to further understanding of the intestinal microbiota in humans and provide new ideas to
develop regulation strategies for human health.

Key words: intestinal microbiota, health regulation, enteropatia, obesity, diabetes
