Abstract

The comparative study of the signs of pathogenicity in 724 enterobacterial strains and in some species of nonfermenting microorganisms isolated from the feces of 115 somatic patients with intestinal dysbacteriosis and 80 healthy persons (565 strains) has revealed that microorganisms belonging to the same species may essentially differ in their occurrence, in the activity of the enzymes (DNAase, RNAase, phosphatase) which they release into the culture medium, as well as in their capacity to give the positive reaction with Congo red. At the same time, the cultures isolated in cases of intestinal dysbacteriosis have been found to be biologically more active.

摘要

对从115例患有肠道菌群失调的躯体疾病患者粪便中分离出的724株肠杆菌菌株以及一些非发酵微生物菌株，与从80名健康人（565株菌株）粪便中分离出的菌株进行致病性特征的比较研究发现，属于同一物种的微生物在其出现频率、释放到培养基中的酶（DNA酶、RNA酶、磷酸酶）活性以及与刚果红产生阳性反应的能力方面可能存在本质差异。同时，已发现肠道菌群失调病例中分离出的培养物在生物学上更具活性。
