| Abstract: | The electrophoretic mobility of the cells of Staph. aureus cultivated on the medium with ristomycin is markedly decreased at pH 3.0-5.0. This indicates that ristomycin added to the cultivation medium lowers the number of the phosphate groups in teichoic acids of the staphylococcal cell wall. The effect of ristomycin on the cells of the staphylococci was studied in vitro during the process of their incubation. It was shown that almost within the first minutes of the incubation ristomycin interacts immediately with the ionogenic groups of the cell wall and first of all with the phosphate groups of teichoic acids. |
