STRONGYLOIDIASIS OF YOUNG CATTLE IN THE KALUGA REGION

Strongyloidiasis is a widespread invasive disease of animals and humans caused by nematodes from the order Rhabditida of the family Strongyloididae, which includes more than 50 species. Strongyloides are developed in the same way in all types of animals with the alternation of parasitic and free-living generations (in analogy with heterogonies). Strongyloidiasis is a zoonosis; when it is diagnosed, autoinvasion is possible. Strongyloidiasis causes damage to the gastrointestinal tract, respiratory organs, circulatory and lymphatic systems in the hosts of the invasion, and leads to metabolic disorders, fever and anemia. Since the larvae migrate through the circulatory and lymphatic system, there is some suggestion that animals can become infected intrauterine. There is evidence that strongyloidiasis among animals causes vasculitis of the optic nerve, damage to the nervous system and brain with characteristic symptoms (loss of vision or consciousness, epilepsy, convulsions). When the larvae penetrate through the skin, dermatitis and ulcers occur. Infected animals refuse to eat, which leads to their cachexy and even death. In most cases, strongyloidiasis affects young livestock animals (piglets, calves, lambs, foals) aged up to 3-6 months. The difficulty of controlling strongyloidiasis lies in the fact that Strongylids are geohelminths and animals can become infected by contact with infected soil and litter. According to the study results, strongyloidiasis was detected in newborn calves, which indicates the need for testing for strongyloidiasis and deworming not only young animals, but the entire breeding stock.
