A microscopic organism which lives as a parasite in human blood. It is transmitted by the bite of insects such as the tsetse fly and causes sleeping sickness and other serious illnesses.
A genus of parasitic protozoans that move by means of a long trailing flagellum and a thin wavy membrane, which project from the body surface. Trypanosomes undergo part of their development in the blood of a vertebrate host. The remaining stages occur in invertebrate hosts, which then transmit the parasites back to the vertebrates. T. rhodesiense and T. gambiense, which are transmitted through the bite of *tsetse flies, cause sleeping sickness in Africa. T. cruzi, carried by reduviid bugs, causes Chagas disease in South America.
A genus of microscopic parasites, several of which are responsible for causing sleeping sickness and some allied diseases.
A genus of parasitic, flagellate protozoa found in the blood of many vertebrates, including humans. The protozoa are transmitted by insect vectors. The only two species relevant for disease in humans are T. brucei and T. cruzi.
A kind of protozoan parasite from the genus Trypanosoma that infects the blood plasma of animals and humans, causing disease and spread by insects.
