[The characteristics of the contact of proteolytic strains of Proteus mirabilis and Klebsiella pneumoniae with enterocytes in vivo].

The relationships of opportunistic P. mirabilis and K. pneumoniae, both having proteolytic properties, with enteric cells in white mice have been studied on a ligated intestinal loop, used as an experimental model, by electron microscopy.

[The adhesive and colonizing properties of Aerococcus viridans].

On the basis of experiments carried out in the course of this study the conclusion can be made that one of the mechanisms of the preventive effect of aerococci, the representatives of the indigenous microflora of the gastrointestinal tract, lies in their capacity for adhesion to and colonization of the mucous membrane, this enhancing the resistance of the enteric tract to infections. These properties of anterococci substantiate good prospects of using M-bacterin (live lyophilized aerococcal culture) for the control of enteric infections and dysbacteriosis.

[Structural characteristics of the remote interaction of Shigella and Salmonella with enterocytes of experimental animals].

The electron-microscopic analysis of the adhesion of Shigella and Salmonella nonfimbriated strains to the surface of enterocytes of laboratory animals in vivo and in vitro has revealed the presence of structural links, whose formation occurs with the participation of the glycocalix of the interacting cells and the extracellular gel.
