文档介绍：人体肠道微生态最新研究
摘要:人体肠道中含有种类繁多的微生物,这些微生物在人体肠道中共同构成肠道微生态。肠道为微生物提供生存环境,而微生物也发挥许多有利于人体的功能。肠道菌群的种类和比例随着人体的年龄、饮食****惯等变化而变化。肠道微生态存在微生态平衡和微生态失调两种状态。微生态调节剂可调通过其中的益生菌和(或)其代谢产物对整宿主体内的微生态区进行调整,使其从失调状态到保持平衡状态。随着微生态制剂的迅速发展,益生菌的使用安全性问题也备受关注。本文对人体肠道微生态的研究、微生态制剂的应用及安全性问题展开综述。结合目前最新的研究,对肠道微生态的进行分析及展望。

The latest study of the human gut microecological
Abstract: In the human intestine,there is a wide variety of anisms. These microbes form the intestinal microecology. Gut is the living environment of microbes , and microbes is so beneficial to human. The types and the proportion of intestinal flora will change when human’s age or eating habit was changed. Intestinal microecology has two states, one is microecological balance and the other is microecological disturbance. Microecological can be regulated from disturbance to balance by useing probiotic and ( or ) its metabolites. With the rapid development of microecologics, the security problems of using probiotic are of concern. The research of human gut microecological as well as the security problems and the using of microecologics were been discussed in the article. According to the latest research, analysis and prospect about gut microecological were giving out.

1 人体肠道微生态的概况
人体内含有的微生物数量庞大,组成复杂。按照正常微生物群在微生态系统中所占的空间不同,通常将人的微生态系统分为以下几类:口腔微生态系统、胃肠道微生态系统、泌尿道微生态系统、生殖道微生态
