An investigation into the incidence and pathology of natural trypanosomiasis of bushbuck (Tragelaphus scriptus) and kudu (T. Strepsiceros)

  • D. C. Knottenbelt


Haematological and biochemical data were obtained from44 bushbuck (Tragelaphus scriptus) and 10 kudu (T. strepsiceros) shot in the Matsikite area of Rhodesia which carries populations ofGlossina morsitans andG. pallidipes. Pathological material was obtained from12 bushbuck and four kudu. Examination of the material revealed aTrypanosoma congolense infection in a bushbuck and a mixedT. congolense/T. brucei infection in a kudu, neither showing any apparent pathological effect. All the kudu and bushbuck showed an intense haemosiderosis of the spleen.

Du matériel hématologique et biochimique a été recueilli sur quarante quatre céphalophes et dix Koudous tués dans la région de Matsikite en Rhodésie, où existentGlossina morsitans etGlossina pallidipes.

Du matériel pathologique a été également obtenu de douze céphalophes et de quatre Koudous. Leur examen a permis de déceler la présence deT. congolense chez un céphalophe ainsi qu'une infection mixteT. congolense/T. brucei chez un Koudou, aucun de ces deux animaux n'a montré de signe apparent de maladie. Tous les céphalophes et Koudous examinés ont présenté une intense hémosiderose de la rate.


Se obtuvieron datos hematológicos y bioquímicos de 44 Bushbuck (Tragelophus scriptus) y 10 Kudu (T. strepsiceros), muertos en el área Matsikite de Rodésia. En esta zona existen poblaciones deGlossina marsitans yG. Pallidipes. Se obtuvó material patológico de doce Bushbuck y 4 Kudu. El exámen reveló infección conTrypanosoma congolense en un Busbuck y una infección mixta deT. congolense/T. brucei en un Kudu. Ninguna de los espécies mostro efectos patológicos aparentes. Todos los animales muertos tenían hemosiderosis intensa en el bazo.
