Larval cyathostominosis in horses

Small strongyles are the most common parasites of horses, capable of surviving different climate conditions. Though the infection is usually asymptomatic, young horses are considered more prone to developing a parasitic syndrome called larval cyathostominosis. In most cases, gastrointestinal symptoms are most prevalent. Treatment is based on the use of fenbendazole and moxidectin. Diagnosis is difficult and serological methods are still under development. The main prevention methods include regular coprological testing, pasture rotation, co-grazing with ruminants, and regular removal of faeces from the pasture.
