The experiments were designed to examine the effect of Ascaris suum body fluid in the experimental erysipeloid in mice. The experiments were conducted in 3 series depending on the time of the first dosis of Ascaris fluid in relation to the time of infection with Erysipelothrix rhussiopathiae. In no case could death be prevented in mice infected with erysipeloid, though in vitro experiments showed the bacteria to be sensitive to the effect of the fluid (Przyjałkowski, 1962). The only positive effect consisted in the attenuated course of the disease, this being expressed by the increased survival rate of animals which were given the Ascaris body fluid.
