Trypanosoma (Duttonefla) vivax.
Although Trypanosoma vivax was first discovered in 1905 (Ref. 1), the fact that most stocks of this parasite are restricted to ruminant hosts has retarded investigation of this species compared with the experimentally more amenable T. brucei and T. congolense. The veterinary importance of T. vivax (Box 1) and a recent report suggesting that T. vivax may have an even more extended range than previously thought (Box 2) prompts an evaluation of the current knowledge of the biology of this trypanosome.
