人体肠道里生活着超过1000种以上的微生物,统称为肠道微生物。这些微生物细胞总量约为人体细胞总数的10倍,而其编码的基因总量更是人体基因总数的100倍。肠道微生物和宿主在长期进化中形成了一个具有协同作用的共生复合体,构成了肠道微生态。微生物细胞之间、宿主细胞之间及微生物和宿主细胞之间,存在着一个复杂的细胞通讯网络,包括微生物对宿主的作用、宿主对微生物的作用,不同的微生物间也可发生交互作用,从而维持肠道微生态
More than 1000 kinds of microorganisms live in human intestine, collectively referred to as gut microbes. The total number of these microbial cells is about 10 times the total number of human cells, and its total number of genes encoded more than 100 times the total number of human genes. Intestinal microorganisms and hosts form a synergistic symbiotic complex that forms gut microbes during long-term evolution. Microbial cells, host cells and between microorganisms and host cells, there is a complex cellular communication network, including the role of microorganisms on the host, the role of the host on the microorganisms, microorganisms can also interact with each other, and thus Maintain intestinal microflora
