A group of conjugation plasmids identified in the cells of wild strains of E. coli isolated from the people and animals were examined. The majority of plasmids showed the ability to inhibit Flac plasmid genetic transfer functions. However, some of them differed in the levels of inhibitory activity. Similar experiments with derepressed F-like pAP22-4 plasmid demonstrated that it is marked by a less ability (as compared with Flac plasmid) to be inhibited by different plasmids. This circumstance is possibly related to the specificity of the genetic regulation of plasmid transfer functions.
对从人和动物中分离出的大肠杆菌野生菌株细胞中鉴定出的一组接合质粒进行了检测。大多数质粒显示出抑制Flac质粒遗传转移功能的能力。然而，其中一些质粒在抑制活性水平上有所不同。对去阻遏的F样pAP22 - 4质粒进行的类似实验表明，与Flac质粒相比，它被不同质粒抑制的能力较弱。这种情况可能与质粒转移功能的遗传调控特异性有关。
