[Intraepithelial shigellae invasion of the intestinal mucosa in patients suffering from acute Sonne dysentery].

Data are presented on detection of intraepithelial localization of shigellae in the biopsy materials of the large and small intestine mucosa of the patients with various forms of acute Sonne dysentery, in comparison with the clinico-morphological picture of the disease.
