Promising medicinal plants for treatment of helminths of bison

Bison bonasus (Linnaeus, 1758) and B. bison (Linnaeus, 1758) are mammals placed in the Red Book of the International Union for Conservation of Nature. Populations of those species of animals are under threat of extinction. Therefore, developing practical measures for their protection is of great significance. However, one way of improving the population of bisons is integrated control of their helminths. The article generalizes the data about the helminth fauna of B. bonasus and B. bison, as well as data on relatively medicinal plants with anthelmintic properties. The results of the analysis indicate the existence of more effective medicinal plants that could be used to develop novel anthelmintic drugs. Less effective anthelmintic plants may be consumed by animals in pastures or with hay in the conditions of stable maintenance. Helminths in bison populations should be controlled using plant-based anthelmintic drugs taking into account infections in animals in particular herds of bisons by more or less dangerous helminths.
