In the natural biocenoses - parasites are a component part of living nature. However, in the socio-economic conditions, they act as causative agents to disease in humans, animals and plants. Biological pollution of the environment is mainly associated with the organic pollution. This, is caused by the spreading and accumulation in the environment of the living pathogens - pathogens of the infectious and parasitic diseases (viruses, bacteria, fungi, protozoa, eggs and larvae of helminths, insects and ticks) in an amount that exceeds that limit, after which there is a real threat for infection. Phytohelminths cause enormous damage to agricultural production, reducing crop productivity and their resistance to various diseases. However, the harmfulness by phytohelminths is not limited to this: the nutritional quality of the affected plants is reduced, which correspondingly affects the organism of the animal that feeds by such plants. Such helminths, which parasitize to human and animal organisms, and the phytohelminths secrete metabolic products, which negatively affect not only the vegetal organism (plants), but also the animal organism, which eats these affected plants. It has been experimentally demonstrated that the metabolic products of phytohelminths have a depressing effect on antibody synthesis and phagocytosis, increase the erythrocyte sedimentation reaction and slow down the blood coagulation process, in animals that were injected subcutaneously with an extract from the affected parts of potatoes with Ditylenchus destructor species.
