The present paper was aimed at evaluating hematological changes in rabbits experimentally infected by Trypanosoma evansi. Six male rabbits divided in to two groups were used, being the control group composed of non-infected animals and the test group composed of animals infected by T evansi. The animals were kept at room temperature and were analyzed during 120 days, by blood collections oil days 1, 20, 40, 60 and 120. Hematological changes were observed in the second and third blood collections and the animals with parasitism had a decrease in blood cells, hemoglobin concentration, hematocrit and mean capsular hemoglobin concentration (MCHC) and an increase in the mean capsular volume (MCV) suggesting a macrocytic hypocrhomic anemia on days 20, 40 and 60. The infected rabbits also presented leucopenia and lymphopenia, as well a significant decrease of neutrophil and monocite counts in comparison to those of the control group.
