肠道菌群差异与健康的研究进展

Recent advances in relationship between diversity of gut microbiota and health

自人类微生物组计划启动以来,研究发现人体肠道内存在有1 000多种共生菌,主要包括Bacteroidetes、Firmicutes、Proteobacteria等菌门（[1]）,它们寄居在肠道的不同部位,通过特有的菌群结构、菌群活动、代谢产物等来影响机体的新陈代谢,

Trillions of microbes inhabit the human intestine,forming a complex microecological community. It has been found that the gut microbiotas contribute nutrients and energy to the host,and they are also involved in the occurrence and development of human diseases. With the continuous development of related research,there is increasing evidence suggesting a close relationship between gut microbiota and human diseases. The discovery of this relationship affects the development of modern health care individually. In this review,we focus on the influence factors to the diversity of gut microbiota,which has influences on colorectal cancer,aging,obesity,immunity,drug effects and malnutrition.
