[Ultrastructural organization of Salmonella typhimurium cells during long-term starvation and transfer to an unculturable state].

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.
