 A wide variety of indigenous microorganisms colonized in the human intestine could continuously affect human health. Interaction between host humans and gut microbes forms a unique microbiota for each individual, and established symbiotic relationship is important to maintain human healthy state. Disrupted bacterial composition and following change of bacterial metabolites, that is dysbiosis, have been found to be associated with the development of various diseases such as inflammatory bowel diseases and lifestyle-related diseases. Our research projects are as follows : ��1�� Comparative analysis of gut microbiota and intestinal environment between healthy and diseased state, ��2�� exploratory research on food components and microbial agents which could ameliorate diseased conditions through modifying intestinal environment,��3��formation process of human gut microbiota and influencing factors.
