General information
Trypanosoma equiperdum
Infection with Trypanosoma equiperdum, also known as dourine, is a chronic or acute infectious disease in equids, which is transmitted directly between animals during mating. Infected equids are the only natural reservoir; the pathogens are present in the genital secretions of both mares and stallions. Incubation period, severity and duration of the disease vary considerably. Subclinical infections are possible; donkeys and mules are more resistant to the pathogen. Clinically, affected animals show inflammation of the outer genitals with depigmentation of the mucosa up to
peripheral-neurological disorders/paralysis. Particularly in Asia and Africa, Trypanosoma is still widespread; Central Europe is currently considered free from Trypanosoma equiperdum. Export-relevant test.
Trypansoma evansi
Trypansoma evansi is present in North Africa, the Middle East, Latin America and Asia.
Transmission mainly occurs mechanically through blood-sucking insects. Infections have been described in various mammals, but especially in camels, cattle and horses. However, dogs can also be infected. In contrast to camels, clinical signs in dogs are often mild.
