Trypanosoma evansi is a species of excavate trypanosome in the genus Trypanosoma that causes one form of surra in animals.[1] It has been proposed that T. evansi is—like T. equiperdum—a derivative of T. brucei.[2] Due to this loss of part of the mitochondrial (kinetoplast) DNA T. evansi is not capable of infecting the invertebrate vector and establishing the subsequent life-stages.[3][4] Due to its mechanical transmission T. evansi is not restricted to transmission via the tsetse fly but shows a very broad vector specificity including the genera Tabanus, Stomoxys, Haematopota, Chrysops and Lyperosia.[5] It rarely causes disease in humans,[6] indeed, it has only been recorded in cases where the patient lacks a normal component of human serum, Apolipoprotein L1.[7] T. evansi is very common in India and Iran [8] and causes acute disease in camels and horses, and chronic disease in cattle and buffalo. In Pakistan, it has been found to be the most prevalent trypanosome species in donkeys.[9]
