Zool. [mod.L. f. Gr. τρύπανον borer + σῶμα body.] A genus of flagellate infusorial protozoa, species of which are parasitic in the blood of man and other animals, causing specific diseases, such as sleeping-sickness; an infusorian of this genus. Hence Trypanosomacide [L. -cīda, -CIDE 1], a substance having the property of destroying trypanosomes; Trypanosomai, -somatic, -somatous adjs., of, pertaining to, or caused by trypanosomes; ǁ Trypanosomatosis [mod.L.: see -OSIS] = trypanosomiasis; Trypanosome [a. F. trypanosome (Gruby, 1843)], an infusorian of the genus Trypanosoma; ǁ Trypanosomiasis, pl. -ases [mod.L., after elephantiasis, etc.], a disease produced by infection with trypanosomes; Trypanosomic a. = trypanosomal (in quot. 1906, infected with trypanosomes).
