epizootic lymphangitis
C2Technical/Medical/Veterinary
Definition
Meaning
A chronic, contagious fungal disease affecting the lymph vessels and lymph nodes of horses, donkeys, and mules.
The term refers specifically to a disease caused by the fungus *Histoplasma farciminosum*, characterized by cord-like thickening of subcutaneous lymph vessels, ulcerating skin nodules, and discharge. It is a notifiable disease in many countries and is of significant concern in equine medicine.
Linguistics
Semantic Notes
The term is a compound noun. 'Epizootic' indicates an outbreak of disease affecting many animals of one kind at the same time (analogous to an epidemic in humans). 'Lymphangitis' refers to inflammation of the lymphatic vessels. Combined, it names a specific disease entity. It is distinct from other forms of lymphangitis.

Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'сапом' (glanders), который является бактериальным заболеванием. 'Эпизоотический лимфангит' — это точный, но длинный перевод. В профессиональной среде может использоваться сокращение 'ЭЛ'. Важно не переводить 'lymphangitis' дословно как 'воспаление лимфатических желез', это именно воспаление сосудов.
Common Mistakes
- Misspelling as 'epizootic lymphangitis' (missing the 'h').
- Confusing it with 'glanders', a different bacterial disease.
- Using it to describe non-equine animals.
- Pronouncing 'lymphangitis' with a hard 'g' (/ɡ/) instead of a soft 'g' (/dʒ/).

FAQ
Frequently Asked Questions
No, it is not considered a zoonotic disease. It is specific to equines (horses, donkeys, mules).
No. They have similar symptoms but are caused by different pathogens. Glanders is caused by the bacterium *Burkholderia mallei* and is zoonotic, while epizootic lymphangitis is fungal and not zoonotic.
Treatment is difficult and often prolonged, involving antifungal medications like iodides and sometimes surgical removal of lesions. Due to its contagious nature and control challenges, euthanasia may be recommended in some countries.
It is endemic in parts of Africa, Asia, the Middle East, and historically in Southern and Eastern Europe. It is exotic to the UK, North America, and Australia.
