Abstract

The article comprises the data on the elimination of streptomycin resistance in Staphylococcus aureus after its passage for a long time in a low permanent magenetic field (PMF) with H = 0.5 oe and in a space screened from the geomagnetic field in a permaloy chamber (H = 10(-2). Under these conditions the eliminating effect of the geomagnetic field intensity on the streptomycin resistance of Staphylococci became perceptible after 5--10 their passage under unusual conditions. At the next stages of investigation the eliminating effect of low PMF and of screening was enhanced. At the end of the experiment after 25--40 passages of Staphylococcus aureus throung MF of different intensity the elimination of streptomycin resistance was recorded in all the 11 cultures studied. The quantity of eliminates in populations of experimental substrains of Staphylococcus increased by 1.5--10 and more times as compared to the control.

摘要

本文包含了金黄色葡萄球菌在强度为H = 0.5奥斯特的低强度恒定磁场(PMF)中长时间传代以及在坡莫合金腔中屏蔽地磁场的空间(H = 10⁻²)中传代后链霉素抗性消除的数据。在这些条件下,金黄色葡萄球菌在异常条件下传代5 - 10次后,地磁场强度对葡萄球菌链霉素抗性的消除作用变得明显。在接下来的研究阶段,低强度PMF和屏蔽的消除作用增强。在实验结束时,经过25 - 40次不同强度磁场处理后,在所有研究的11种培养物中均记录到链霉素抗性的消除。与对照相比,金黄色葡萄球菌实验亚菌株群体中的消除数量增加了1.5 - 10倍甚至更多。
