On the possible mechanism of the protective effect of Escherichia.
A model on a HEp-2 cell culture was elaborated, permitting the study of the ability of microbes to be adsorbed an to proliferate on the surface of cells and of the mechanism of their protective effect. The ability of E. coli strains to be adsorbed and to proliferate on the surface of a cell culture was found to differ. It has been demonstrated that the protection of the cell culture from subsequent infection with virulent Shigella can be explained not only by the antagonistic activity of E. coli strains, but also by their ability to be adsorbed and to proliferate on the surface of cells. A similar mechanism of protective effect is supposed in preparations of the Colibacterin type.
