Trypanosoma brucei and T. congolense are the causative agents of Nagana or a similar disease in Africa and Asia. T. evansi is the etiological agent of Surra and the so-called ‘Mal de Cadeiras’ outside the African continent. Dogs are also infected by T. cruzi, the etiological agent of Chagas disease in several American countries, and by T. rangeli, another human parasite, in endemic areas of this species in Latin America. Additionally, a newly recognised trypanosome, namely T. caninum, has been isolated from dogs in south-eastern Brazil.
