[Submicroscopic structure of the streptococcal L forms isolated from a living body].

The authors studied in the L-forms of streptococcus induced in the living organism. Submicroscopic structure of the L-forms under study was analogous to the L-forms of the museum streptococcus strain and to the L-forms of some other bacteria. As revealed on the ultra-thin sections of the protoplast-like cells the intracytoplasmic membrane structures were located close to the cytoplasmic membrane and also passed through the whole cell in the form of a band. The latter was in contact with the nucleotide. The elemental bodies were found in the vesicular and the protoplastic cells, and also in the space between the cells; sometimes they formed groups surrounded by a membrane.
