双歧杆菌是人体内必不可少的一种细菌,它在肠道内存在的多少与人体的免疫、衰老、肿瘤和急慢性感染,以及慢性消化系统疾病的发生有着密切关系。因此双歧杆菌是一种对人体健康有益的菌群。当人体处于健康状态时,双歧杆菌在肠道内大量繁殖作为优势菌群而存在;而当人体患病或衰老时,双歧杆菌就会减少,甚至消失。
Bifidobacterium is an indispensable bacteria in the human body. Its existence in the intestine is closely related to human immunity, aging, tumors and acute and chronic infections, and the occurrence of chronic digestive diseases. Bifidobacterium is therefore a beneficial bacteria to human health. When the human body is in a healthy state, Bifidobacteria multiply in the intestine as a predominant flora; and when the human body is sick or aging, Bifidobacteria diminish or even disappear.
