在人体消化道的不同部位pH 值不相同,细菌亦不相同,且菌群之间存在着生物拮抗作用,它们是相互依存、相互制约的。在正常情况下,它们之间以一定比例保持着平衡状态。但由于某些原因,可使消化道内细菌发生数量上的变化,改变了原来的比例,就引起了菌群失调症。菌群失调症又分为三度:Ⅰ度为可逆性失调,去掉诱因后可自然恢复;Ⅱ度为慢性失调,诱因去掉后,失调状态仍然存在,如慢性腹泻;Ⅲ度为急性失调,为过路菌或外袭菌代替了常住菌,或常住菌的某一种极度繁殖,临床上表现为急性感染症状。
In different parts of the human digestive tract pH is not the same, the bacteria are not the same, and there are biological antagonism between the flora, they are interdependent and mutually restrictive. Under normal circumstances, they maintain a certain balance between the state. However, for some reason, can make the number of bacteria in the digestive tract changes in the number of changes in the original ratio, it caused the flora disorders. Mycosis is divided into three degrees: Ⅰ degree of reversible disorders, remove the incentive to natural recovery; Ⅱ degree of chronic disorders, incentives are removed, the imbalance is still present, such as chronic diarrhea; Ⅲ degree of acute disorders, as Bacteria or germs instead of the resident bacteria, or a kind of common bacteria breeding, the clinical manifestations of acute infection symptoms.
