肠道微生物组研究人体微生物种群结构、人与微生物交互作用、人体微生物功能差异、微生物和疾病的关系.肠道微生物组在维持人体营养、代谢、生长、免疫、防御等方面发挥着重要作用.肠道微生物组紊乱可导致癌症、肥胖、糖尿病、过敏等疾病的发生和发展.因而深入研究肠道微生物组的成分功能和影响因素,将为人类疾病的治疗和预防提供新的靶标.%The study of intestinal microbiota covers human microbial community structure, human and microbial interactions, different human microbial functionals, and the relationship between microbes and disease. Intestinal microbiota plays an important role in maintaining the body's nutrition, metabolism, growth, immune and defense. The disorders of intestinal microbiota led to the development of human diseases such as cancer, obesity, diabetes, and allergy. Thus, the study of the composition, function and influencing factors of the intestinal microbiota will provide a new field for the treatment and prevention of human diseases.
