Equine habronemiosis, known as “summer wounds or summer sores,” is a gastric or more common cutaneous disease in horses. It is caused by larvae of nematodes of the genus Habronema spp and Draschia spp. It is a disease common in horses and can have a significant impact on their health and well-being; Despite being a frequent reason for veterinary consultation in Colombia, few cases have been described, so it is necessary to continue with research focused on risk factors, incidence and prevalence, due to the negative impact of this disease on health and the use of animals. equines generating a great economic impact (Cardona, Violet, Montes, 2016). This article explores its ethology, biological cycle, clinical manifestations, diagnosis, treatment and preventive measures. Habronema nematode lavas, which can be found in bird and mammal feces, are transmitted through flies and horseflies, generating internal and external lesions in horses; Flies deposit larvae in open wounds or mucous membranes, where they can be swallowed; The larvae migrate to the skin forming nodules and subsequently detach and move to the soil, completing their development. Equine Cutaneous Habronemiasis (ECH) is considered a parasitic disease that manifests as skin and/or conjunctival lesions, which can be painful and cause aesthetic and functional problems; It affects skin nodules, ulcers, pruritus and scabs, often seasonally during hot, humid months. The diagnosis of this disease is based on the observation of typical skin lesions and the identification of larvae in tissue or exudate samples. Histology may also be helpful. It is important to differentiate it from other skin conditions in horses, such as sarcoids and squamous cell carcinoma. Treatment includes removal of larvae, cleaning and disinfection of wounds, the use of topical or systematic therapies, such as anthelmintics; At the prevention level, this focuses on vector control, maintaining hygiene in stables, as well as avoiding exposure to flies is essential to prevent habronemiosis.
