Trypanosoma vivax is found throughout the tsetse belt in Africa. It has spread to other parts of Africa, Central America, South America, the West Indies and mauritius. In 1919 T. vivax was reported in the New World for the first time in French Guyana and latter in other parts of South America, Central America, and some Caribbean islands. Bolivia is a sub-tropical country located in the center of South America. It has nine departments. The Santa cruz department is considered one of the most important livestock regions, maintaining a population of 1,598,957 bovines. The German Bush province is located in the extreme south of Santa Cruz departments in the border of Paraguay. In November 1996, we received preliminary reports of anemia and abortions in cattle from bolivian veterinarians of the German Bush province. In February 1997, 87 bovines belonging to 4 ranches of German Bush, were bled from their jugular vein using a vacuum system (Vacuum II, Labnew Campinas, Brazil). The sampled animals, all nelore purebred and crossbreeds (Bos taurus taurus x Bos taurus indicus) between 1 and 9 years old (mean 7 years). The diagnosis was made using the microhematocrit centrifuge test (MHCT). Blood from each sample and the concentrated parasites in the buffy coat of microhematocrit tubes were also used to prepare thin smears. The trypanosomes were identified based on morphological and biometrical data. The clinical signs observed were fever, anemia, abortion, progressive weakness, substantial weight loss in relative short time, and progressive emanciation and lymphonode enlargement. Some animals registered a hematocrit as low as 17%. Thirty-nine of the eighty-seven bovines examined by microhematocrit test were infected by T. vivax (47,82%). The results of this study suggests that T. vivax representa a serious impact to the economy of the region. MenosTrypanosoma vivax is found throughout the tsetse belt in Africa.
