title: [Cellular immune reactions of the white mouse after superinfection with Toxoplasma gondii (author's transl)].
abstract: After superinfection of immunized mice with a virulent strain of Toxoplasma (BK) these mice don't die. There is formation of a cellrich exudate with only very few toxoplasmas. The number of the different exudate-cells (macrophages, big, middlesized and small lymphocytes and heterophils) turn in direction of the lymphocytes in that way, that after the 3rd day of infection 70% of all exudate-cells belong to the group of lymphocytes. They seem to cause the death of the toxoplasmas. After in vitro incubation of trophozoites and exudate-cells of immune mice for 2 hours at 37 degrees C nearly 80% of the added toxoplasmas are killed. Electronmicroscopical pictures show, that this killing is produced by a process of lysis.
