A parasitological and entomological survey was conducted in the Sideradougou area (South of Bobo Dioulasso, Burkina Faso) in order to identify transmission factors of Africa animal trypanosomis. A total of 3600 tsetse flies (Glossina tachinoides, Glossina palpalis gambiensis) werere captured along 120 km of linear gallery forest and half were dissected, PCR analysis was undertaken on parasitologically positive flies (161 G. tachinoides, 92 #G. palpalis gambiensis) to characteize the different trypanosomes. All the results were integrated in a GIS (Geographical Information System). Spatial repartition of the characterized trypanosomes enabled to recognize different areas with specific patterns of infection. Relations with environmental factors are discussed.
