Dourine is an infectious disease caused by a parasite, Trypanosoma equiperdum. It is specific to equines (horses, donkeys) and is not transmissible to humans. Its mortality rate is very high.

What is dourine?

Dourine is a trypanosomiasis, i.e., an infection caused by a blood parasite. The pathogen responsible for the infection is a protozoan, Trypanosoma equiperdum.

Dourine and animals

The infection takes the form of genital edema, paraphimosis, pathognomonic oedematous skin plaques (silver dollar plaques) and terminal neurological signs, with a mortality rate of 50%.
