Bovine Trypanosomosis in the South-Sudan Zone of Burkina Faso. Results of a Serological Survey

Abstract

A serological survey was performed to assess the importance of bovine trypanosomosis in the South-Sudan zone of Burkina Faso. In total, 1403 head of cattle were randomly examined by indirect-ELISA for the detection of antibodies in 18 farming sites spread out in four provinces. Blood sampling was carried out between July and September 1994, and in March 1995. The overall seroprevalence was estimated at 43 ± 2.6%. The seroprevalence was estimated at 41.7 ± 5.6%, 33.5 ± 4.4% and 34.3 ± 5.7% in the provinces of Bougouriba, Kenedougou and Mouhoun, respectively, during the rainy season (July-September 1994), whereas it was estimated at 62.5 ± 4.6% in the province of Comoe during the dry season (March 1995). No significant relationship was observed between the animal phenotype and the seroprevalence. In contrast, the seroprevalence increased significantly with the animal age.
