Nematophagous Fungi Against Strongylata Larvae of Horses
Nematophagous hyphomycetes were found almost in all parts of the world and in different climatic zones. Therefore probably many researchers separate predatory fungi from all soil samples, wherever nematodes can exist. Currently, the prevention and treatment of nematodoses of herd horses by practicing veterinarians is limited to single deworming with the use of known semi-synthetic anthelmintic drugs. It should be noted that the strategy of anthelmintic treatment is aimed at disinfectation directly in the body of animals. Most anthelmintic drugs have antiparasitic properties, and are highly toxic to any endothermic organism. Chemical components of antiparasitic drugs after animal use are excreted in the environment with feces, and, being practically unchanged, continue their strong toxic effect on the pasture biocenosis components. The nematophagous fungi isolated from the permafrost soil of Yakutia belong to the genus Arthrobotrys according to the description of the species, and by morphological and physiological characteristics; 2 strains of predatory fungi L<sub>3</sub>-1 and L<sub>3</sub>-2 have been identified. Nematophagous fungi of the genus Arthrobotrys occupy a certain place in the system of microbiomes that are able to control nematodes.
