[Intracellular parasitism of Shigella in patients with dysentery].

Bioptic specimens of the mucosa of the distal portion of the colon in patients with dysentery, caused by Flexner and Sonne shigellas, were studied by luminescent-serological and electron-microscopy methods. In the cells with unchanged ultrastructure no shigellas were detected. Intracellular localization of shigellas was observed only in cases of deep irreversible alterations in the ultrastructure of the cells.
