Gross and Histopathological Alterations in Experimental Trypanosoma Evansi Infection in Donkeys and the Effect of Isometamidium Chloride Treatment
Trypanosoma evansi (T. evansi) infection causes wasting and fatal animal trypanosomosis. This study was aimed at determining the gross and histopathological alterations in donkeys experimentally infected with T. evansi and the effect of isometamidium chloride treatment. Apparently healthy donkeys (N=18) of mixed sexes were randomly assigned to 3 groups; A1 (Infected-untreated), A2 (Infected, isometamidium-treated) and B (Uninfected, control) of six animals each. Each animal in infected groups had about 2.0x106 T. evansi injected through the jugular vein. Parasitaemia levels were evaluated using HCT and Mice Inoculation Test (support test). Gross and histopathological examinations were also conducted post-infection and post-treatment.
