[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. This investigation has shown that the strains under study are capable of damaging the membrane of the jagged edge of enteric cells at the distance of the spread of proteolytic metabolites. This damage is reversible, presenting as compensatory protective reaction of the cells.
