Topic:Nematodes

Nematodes are parasitic worms that can infect horses, affecting their health and well-being. These parasites typically inhabit the gastrointestinal tract of equines, where they can cause a variety of health issues. Common nematodes affecting horses include strongyles, ascarids, and pinworms. The presence and load of nematodes in horses can lead to symptoms such as weight loss, colic, and diarrhea, and can impact overall performance and health. Monitoring and managing nematode infections is an important aspect of equine veterinary care. This page compiles peer-reviewed research studies and scholarly articles that explore the biology, epidemiology, and management strategies of nematode infections in horses.

Fifteen horses harboring naturally acquired, patent Parascaris equorum and Oxyuris equi infections were equally allotted to 3 treatment groups given (1) injectable vehicle; (2) injectable ivermectin at the dose rate of 200 microgram/kg of body weight; and (3) injectable ivermectin at the rate of 300 microgram/kg. All treatments were given IM in the neck. All animals were killed 14 days after treatment and examined for the targeted nematodes. Regardless of dose rate, ivermectin proved 100% effective in the removal of adult O equi and P equorum infections. Levels of immature P equorum were decre...

is one of the most pathogenic nematodes affecting equids. Larval migration through the cranial mesenteric artery (CMA) with attendant arteritis and thromboembolism can result in fatal non-strangulating intestinal infarction. Once considered a historical disease, recent studies have described the reemergence of this pathogen in several European countries; however, little is known of the current prevalence of in the Canadian horse population. Unassigned: To determine the prevalence of active cranial mesenteric arteritis in horses submitted for postmortem examination to the Diagnostic Services...
