| Trypanosoma melophagium | A nonpathogenic species (related to Trypanosoma theileri) found in sheep throughout the world, and probably in goats as well; the vector is Melophagus ovinus. (05 Mar 2000) |
|---|---|
| Trypanosoma rangeli | A species that parasitises a wide variety of mammals, including humans, in South America and is transmitted by the triatomid bugs Rhodnius prolixus and Tiratoma dimidiata, and probably others; it is apparently nonpathogenic but may be pathogenic in the bug host. (05 Mar 2000) |
| Trypanosoma rhodesiense | A haemoflagellate subspecies of parasitic protozoa that causes rhodesian sleeping sickness in humans. It is carried by glossina pallidipes, g. Morsitans and occasionally other species of game-attacking tsetse flies. (12 Dec 1998) |
| Trypanosoma simiae | A species normally found in warthogs; it is highly pathogenic in pigs and camels, and is transmitted cyclically by tsetse flies and mechanically by bloodsucking flies. (05 Mar 2000) |
| Trypanosoma suis | A species pathogenic for swine in Africa; it is transmitted by tsetse flies. (05 Mar 2000) |
| Trypanosoma theileri | A large, relatively nonpathogenic species found in African antelopes and in cattle in many parts of the world; the parasites are spread by bloodsucking tabanid horseflies. (05 Mar 2000) |
| Trypanosoma triatomae | The agent of south american trypanosomiasis or chagas disease. Its vertebrate hosts are man and various domestic and wild animals. Insects of several species are vectors. (12 Dec 1998) |
| Trypanosoma ugandense | A haemoflagellate subspecies of parasitic protozoa that causes gambian or west african sleeping sickness in humans. The vector host is usually the tsetse fly (glossina). (12 Dec 1998) |
| trypanosoma vivax | An active blood parasite that is present in practically all domestic animals in africa, the west indies, and parts of central and south america. In africa, the insect vector is the tsetse fly. In other countries, infection is by mechanical means indicating that the parasites have been introduced to these countries and have been able to maintain themselves in spite of the lack of a suitable intermediate host. It is a cause of nagana, the severity of which depends on the species affected. (12 Dec 1998) |
