Abstract

Electron microscopic and immunocytochemical studies of Salmonella typhimurium culture were carried out under conditions of cell transfer into an unculturable state induced by carbon, phosphorus, and nitrogen starvation. Morphological variants of bacterial cells were detected in the course of cell culturing under conditions of starvation. Electron microscopy showed that O-antigen was retained in salmonella after long starvation and transfer into an unculturable state.

摘要

在碳、磷和氮饥饿诱导细胞进入不可培养状态的条件下,对鼠伤寒沙门氏菌培养物进行了电子显微镜和免疫细胞化学研究。在饥饿条件下细胞培养过程中检测到细菌细胞的形态变异。电子显微镜显示,长时间饥饿并进入不可培养状态后,沙门氏菌中的O抗原得以保留。
