Trypanosoma

 [tri″pan-o-so´mah]
a multispecies genus of protozoa parasitic in the blood and lymph of invertebrates and vertebrates, including humans; most species live part of their life cycle in the intestines of insects and other invertebrates, the typical adult stage being found only in the vertebrate host. T. gambien´se and T. rhodesien´se cause the Gambian and Rhodesian forms of African trypanosomiasis in humans, and T. cru´zi causes American trypanosomiasis. Other species cause diseases in domestic animals.

Trypanosoma

(tri-pan'ō-sō'mă, trip'ă-nō-),
A genus of asexual digenetic protozoan flagellates (family Trypanosomatidae) that have a spindle-shaped body with an undulating membrane on one side, a single anterior flagellum, and a kinetoplast; they are parasitic in the blood plasma of many vertebrates (only a few being pathogenic) and as a rule have an intermediate host, a bloodsucking invertebrate, such as a leech, tick, or insect; pathogenic species cause trypanosomiasis in humans and other diseases in domestic animals.

TRYPANOSOMA CRUZI: (Orig. mag. ×1000)
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. See: illustration

Trypanosoma brucei

A species with three subspecies: T. brucei brucei, T. brucei gambiense, and T. brucei rhodesiense. The subspecies T. brucei brucei causes a wasting disease in cattle called nagana but does not produce disease in humans. The subspecies T. brucei gambiense causes African sleeping sickness in western and central Africa. The subspecies T. brucei rhodesiense, transmitted by the tsetse fly, causes African sleeping sickness in eastern and southern Africa.

Trypanosoma cruzi

The causative agent of American trypanosomiasis (Chagas disease). It is transmitted by triatomids (bloodsucking insects of the family Reduviidae).
