Abstract

The probability of a Glossina pallidipes picking up an infection from a single blood meal in Lambwe Valley was estimated to be 0.0092 for Trypanosoma vivax, 0.0028 for T. congolense, 0.00097 for T. brucei and 0.00024 for the human infective T. brucei. In cattle, the prevalence of blood protozoa was Trypanosoma spp. 5.55%, Babesia spp. 2% and Theileria spp. 33.06%. Thirty-eight point three per cent of the cattle with trypanosomes also had Theileria spp., 2.12% of the cattle with trypanosomes also had Babesia spp. and 88.28% of the cattle with babesia had also Theileria spp.

Résumé

La probabilité pour un Glossina pallidipes de transmettre une infection à partir d'une sucée de sang dans la Vallée le Lambwe a été estimée à 0,0092 pour la Trypanosoma vivax, 0,0028 pour T. congolense, 0,00097 pour T. brucei et 0,00024 pour contagieux humain T. brucei. Chez les bovins, la prévalence du protozoaire du sang était: Trypanosoma spp. 5,55% Babesia spp. 2% et Theileria spp. 33,06. Trente huit virgule trois pour cent de bovins ayant le trypanosomes avaient aussi le Theileria spp. 2,12% des bovins ayant des trypanosomes avaient aussi le Babesia spp. et 88,28% des bovins ayant le babesia avaient aussi le Theileria spp.
