Staphylococcus epidermidis strain No. 17 containing the bacteriocinogenicity plasmid and incapable of the spontaneous loss of this plasmid was studied. When the contact between the dividing cells was broken by shaking, the cells without the plasmid were shown to appear in the population starting from the 30th minute of cultivation. In all cases the loss of the plasmid due to the action of acridine orange at 37 degrees C and 44 degrees C, as well as in cultivation at 44 degrees C, occurred more frequently when the growing population was shaken than in the absence of shaking. This suggests the possibility of transferring the plasmid controlling bacteriocinogenicity in the process of the growth of staphylococcal population.
对含有产细菌素质粒且该质粒不会自发丢失的表皮葡萄球菌17号菌株进行了研究。当通过振荡破坏分裂细胞之间的接触时，从培养第30分钟起，群体中就会出现不含质粒的细胞。在所有情况下，无论是在37℃还是44℃下，吖啶橙作用导致的质粒丢失，以及在44℃培养时，生长中的群体振荡培养时质粒丢失的频率都高于不振荡培养时。这表明在葡萄球菌群体生长过程中存在转移控制细菌素产生的质粒的可能性。
