title: [Immunosuppressive action of the lethal toxin of Bacillus anthracis in mice].
abstract: In experiments on inbred mice infected with B. anthracis capsular strain 71/12 of Tsenkovsky's second vaccine B. anthracis lethal toxin introduced in mixture with spores has been shown to aggravate anthrax infection in CBA mice susceptible to anthrax, while producing a faint effect on the infectious process in BALB mice with hereditary resistance to anthrax. B. anthracis purified edema toxin has been found to produce a weaker aggravating effect with respect to anthrax infection than the lethal toxin. As revealed in these experiments, the capacity of the lethal toxin to suppress the activity of peritoneal macrophages in vitro is the more pronounced, the more resistant to anthrax are the mice used as the donors of these macrophages. The mechanism of hereditary immunity which may ensure resistance to infection in the presence of immunosuppression is discussed.
