Evaluation of the vectorial capacity of Glossina palpalis gambiensis (Bobo Dioulasso) for Trypanosoma brucei brucei EATRO 1125

Abstract

A total of 440 teneral Glossina palpalis gambiensis received one single bloodmeal on a guinea pig infected chronically with Trypanosoma brucei brucei EATRO 1125. Metacyclic infections were present in 11.29 % of the flies, in 2.32 % infections were limited to procyclical stages. No significant difference in vectorial capacity was observed between male and female flies, the level of metacyclic infections being 13.19 % in the former and 9.55 % in the latter. The parasitaemia level, the percentage of stumpy forms at the moment of the bloodmeal and the maintenance conditions of the flies seemed to influence the infection of the flies.
