Epizootic lymphangitis in horses: a review of the literature.

The research article provides a comprehensive review of Epizootic lymphangitis, a common infectious disease in horses, discussing its diagnosis, effects, and treatment procedures.

Overview of Epizootic Lymphangitis

• The research begins by explaining that Epizootic lymphangitis is a prevalent infectious disease that affects horses and other equines in specific regions. Its occurrence rate varies based on geography and the animal’s age.
• The disease is primarily characterized by a distinctive cord-like appearance in the subcutaneous lymphatic system of the animals and the formation of cutaneous pyogranulomas, or pus-filled granulomas beneath the skin.
• The discharge from the pyogranulomas contains noticeable pear-shaped or spherical bodies of the causative microorganism, Histoplasma farciminosum.

Diagnosis of Epizootic Lymphangitis

• The article suggests several methods for diagnosing Epizootic lymphangitis. These include observing common microorganisms in stained smears, culture and tissue sections.
• Serological tests, which identify disease-specific antibodies in a horse’s blood, are also mentioned as a diagnostic method.
• Additionally, a skin hypersensitivity test can be performed to support the diagnosis.

Treatment and Prevention of Epizootic Lymphangitis

• Once the horse is confirmed to be suffering from Epizootic lymphangitis, the research describes Amphotericin B as the preferred pharmaceutical treatment.
• For prevention, particularly in areas where the disease is endemic, a modified-live or an inactivated vaccine is available to provide immunity against the disease
• These vaccines, if used appropriately, prove effective in controlling and managing the spread of the disease.
