[Morphologic characterization of the contemporary dysentery caused by Shigella flexneri 2A].

There is a tendency in St. Petersburg since 1990s to an increase of dysentery morbidity and lethality mainly caused by Flexner Shigella 2a. Morphology of the disease in adults is given on the material of 286 necropsies in 1993-1994 in the S. P. Botkin Infectious Hospital. Males (mean age 50 years) and among them chronic alcoholics prevailed; females (mean age 70 years) were frequently with a grave cardiovascular pathology. Advanced inflammation (fibrinous, ulcerative and hemorrhagic) of all colon and distal part of the small bowel was a common finding. Hemorrhagic infarctions of the ileum which were not described so far were observed in 10% of the cases.
