Intestinal Microecology in Digestive System Health and Diseases / 胃肠病学

ABSTRACT

Gastrointestinal tract contains a wide variety of host-specific microbial communities that not only adapt to the unique and diverse environment in the stomach and intestine, but also respond quickly to all kinds of variants from outside of the body. A series of biochemical signals are occurred for interacting with the host to coordinate the exchange of nutrients and regulate the immune function. The interaction between host and microorganisms is based on homeostasis; dysbiosis of intestinal microbiota contributes to the initiation and development of diseases. The relationship between microbes and host from the perspective of microecology, and the relationship between intestinal microecology and digestive system diseases were summarized in this article.
