Combined effects of ionizing radiation and agents of biological nature on the body of animals

As a result of the work carried out, proceeding from the conceptual position of radiation parasitology about a certain commonality of the mechanisms of the pathogenic effect of ionizing radiation and parasitic agents on living organisms, we determined the conditions for modeling parasitic invasion, as well as combined radiation-helminthic damage to the body using optimal doses of agents of invasive etiology. Irradiation of rabbits at a half-lethal dose of 7.0 Gy, produced before infection with passaluros at a dose of LD50 (1500 eggs of P. ambiguus), aggravates the course of the invasive process and promotes its generalization, accelerating the death of animals. The combined radiation-helminthic lesion proceeds quickly with the absolute death of all affected animals.
