title: [Ticks and hemoparasitoses of livestock in Senegal. III. The Northern Sudan area].
abstract: The authors describe the results of a study on ticks and hemoparasitoses of cattle and small ruminants in the Senegalese north-sudanian area. For 15 months, 40 bovine, 40 sheep and 40 goats received a routine dipping treatment, aimed at the determination of the tick population dynamics together with an accurate localization of the preferential sites for the different species. The following parasites were collected from the animals: Hyalomma marginatum rufipes, H. truncatum, Rhipicephalus lunulatus, Rh. e. evertsi, Rh. sulcatus, Rh. senegalensis, Boophilus decoloratus. Joint studies were conducted on the hemoparasites using blood smear and splenectomy. Among bovine, Anaplasma marginale, Ehrlichia bovis, Theileria mutans, Th. velifera, Trypanosoma congolense, T. brucei and microfilariae from Setaria labiatopapillosa were observed. Babesia bigemina was observed after a splenectomy. In small ruminants, the detected infections are brought about by A. ovis, Th. ovis and T. vivax. Hematocrite value of apparently healthy animals are studied as well as the seasonal variation of this hematological factor.
