Trypanosoma evansi is a protozoan trypanosome in the genus trypanosoma that causes one form of the surra disease in animals. It has been proposed that T. evansi is - like T. equiperdum- originally a subspecies of T. brucei brucei.[1] Due to this loss of part of the mitochondrional DNA T. evansi is not capable of infecting the invertebrate vector and establishing the subsequent life-stages [2] .[3] Due to its mere mechanic transmission T. evansi is not restricted to transmission via the Tsetse-fly (glossina sp), but shows a very broad vector specificity including the genera Tabanus, Stomoxys, Haematopota, Chrysops and Lyperosia.[4] It rarely causes disease in humans.[5] It is very common in India and causes acute disease in camels and horses and chronic disease in cattle and buffaloes.
