身体内的另一个自己随着对于微生物的进一步研究,科学家发现人的胃和盲肠中,存在着种类极多、数量极大的微生物群体。一个正常成年人肠道内的细菌总重量可达1.5千克,数量达到10~(14)个,是人体细胞总数的10倍。有人风趣地说:从数量上来看,我们人类并不应该被称为人类,而应被称作“细菌集团”。这个庞大的群体,就是肠道菌群。肠道菌群——尚未被认识的器官根据细菌在肠道内的不同的生理功能,它们被分为共生菌(益生菌)、条件致病菌(中性菌)和致病菌(有害菌)三大类,它们之间形成并保持一个相对稳定的微生态系统,共同参与人体多种重要
The other one in the body With further research on microbes, scientists have found that there is a very large and large number of microbial populations in the stomach and cecum. A normal adult intestinal bacteria in the total weight of up to 1.5 kg, the number of 10 to (14), is 10 times the total number of human cells. It is funny to say: From a quantitative point of view, we humans should not be called human beings, but should be called “bacteria group ”. This huge group, is the intestinal flora. Gut flora - unidentified organs Depending on the different physiological functions of the bacteria in the intestine, they are divided into symbionts (probiotics), conditional pathogens (neutral bacteria) and pathogenic bacteria (harmful bacteria) Three categories, between them to form and maintain a relatively stable micro-ecosystem, to participate in a variety of important human body
