[An electron microscopic study of the interaction between salmonellae and the epithelium of rat ileum].

Electron-microscopy studies of the interaction between salmonellas and the epithelium of the ileum in rats showed that the microbes penetrated into enterocytes of rats in crypts. This is, apparently, associated with the absence of manifested glycocalix on the plasmatic membrane of microvilli of the crypt cells. Salmonellas penetrated into cells, as it seems, during the rupture of the apical plasmatic membrane. The salmonellas found in the prismatic cells showed no signs of degeneration nor digestion. Organells of the epithelial cells in the intraepithelial localization of salmonellas did not undergo any essential changes.
