菌群失调(dysbacteriousis)?指在原微生物环境中,微生物群落或种群发生了定量或定性的异常变化。以量的变化为主,因此菌群失调又称比例失调。根据失调的程度,菌群失调可分为三度:一度失调又称潜伏型菌群失调,只能从细菌定量检查上发现有变化,在临床上往往没有表现或只有轻微的反应;二度失调又称局限型菌群失调,为不可逆的失调,菌群内生理性波动转变为病理性波动,临床上多有慢性病的表现;三度失调,又称为菌群紊乱症,也称为菌交替症或二重感染,表现为原来 Dysbacterial (dysbacterial) refers to the original microbial environment, microbial communities or populations have a quantitative or qualitative abnormal changes. Changes in the amount of the main, so the flora imbalance, also known as the proportion of disorders. According to the degree of disorders, flora can be divided into three degrees: once dysfunction, also known as latent flora, can only be found on bacterial quantitative examination of changes in the clinical often have no performance or only minor reactions; second degree of disorder Also known as the limitations of flora, irreversible disorders, physiological fluctuations within the flora into pathological fluctuations, the clinical manifestations of chronic diseases; third degree disorders, also known as flora disorder, also known as bacteria alternating Symptom or double infection, manifested as the original
