[Electron microscopic study of the interaction of Yersinia pseudotuberculosis with macrophages and HeLa cells].
The comparative electron-microscopic study of early stages of the interaction of Y. pseudotuberculosis virulent strain (No. 282) with "professional" (macrophages) and "nonprofessional" (HeLa cells) phagocytes has been carried out. The character of the intimate mechanism of this interaction has been found to be essentially different. The common feature for both systems is the adsorption of bacteria and their penetration into cells due to phagocytosis. But the subsequent fate of Y. pseudotuberculosis is different. In HeLa cells they are isolated from the cytoplasm by multilayer membrane structures, thus remaining morphologically intact. In macrophages the destruction of the microbe in phagolysosomes occurs.
