Epizootic Lymphangitis in Horses

Seek veterinary advice if you suspect this disease.

Epizootic Lymphangitis is a contagious and chronic mycosis in horses caused by the fungus Histoplasma farciminosum. It primarily affects the skin and lymphatic system, causing nodules, abscesses, and ulceration that can spread and lead to chronic lymphatic obstruction.

The disease is endemic in parts of Africa, Asia, and South America, posing significant challenges due to its chronic nature and limited treatment options.

Treatment

Treatment of Epizootic Lymphangitis in horses involves a multifaceted approach due to the chronic and debilitating nature of the disease. It typically includes systemic antifungal medications such as potassium iodide, itraconazole, or terbinafine to combat the fungal infection.
Surgical intervention may be necessary to remove nodules and abscesses, particularly in localized and persistent lesions. Supportive care, including wound management, bandaging, and nutritional support, is essential to aid in healing and prevent secondary infections.

Close veterinary supervision and long-term management are often required to achieve successful outcomes in affected horses.

Prevention

Preventing Epizootic Lymphangitis in horses involves strict biosecurity measures to reduce the risk of fungal transmission. This includes quarantine and isolation of new horses, regular screening for early detection of lesions, and maintaining hygienic stabling conditions. Additionally, controlling biting insects and avoiding sharing of equipment between horses can help minimize the spread of the disease in endemic regions.
