The study of a number of main growth characteristics of S. flexneri (S) cells during the first and second cycles of their cultivation in a solid culture medium in Peshkov's chamber from seed material, nonsynchronized and synchronized by C. E. Helmstetter's method, has revealed that this method does not permit obtaining completely synchronized cultures. Four physiological cell clusters, differing in the time of generation, growth rate, size at the beginning and the end of the cycle and the time of adaptation, have been detected.
对弗氏志贺氏菌（S）细胞在固体培养基中于佩什科夫氏培养室进行第一代和第二代培养期间的一些主要生长特性进行研究，所用种子材料分别为非同步化的以及通过C.E. 赫尔姆施泰特方法同步化的，结果表明该方法无法获得完全同步化的培养物。已检测到四个生理细胞群，它们在产生时间、生长速率、周期开始和结束时的大小以及适应时间方面存在差异。
