[Changes in the ultrastructure of staphylococci in kidney tissue in experimental infection]

A study of ultrathin sections fo the kidney tissue of mice infected with staphylococci showed intracellular localization of the bacteria. In vivo there occurred a morphological reconstruction of external layers of the cell wall of staphylococci, and lysis of individual staphylococci. The middle part of the cell wall and the cytoplasmic membrane proved to be the structures the most stable to lysis. Specific changes of bacteria similar to the changes noted with the action of penicillin on staphylococci in vitro followed effective penicillin therapy of mice infected with staphylococci.
