INTRODUCTION At the East part of DRC, anecdotal reports are advancing several causes of unsuccessful campaigns of vaccination by the time going: rumors about use of vaccines for killing purpose, injection of vaccine to decrease the reproductive potential in coming generations, use of vaccines by some rebellions and neighboring countries to kill children(More)
The authors report on the results of experimental infections of teneral (age < 32 hours) and non-teneral (age between 80 and 96 hours) Glossina palpalis palpalis, G. p. gambiensis and G. morsitans morsitans with Trypanosoma congolense IL 1180. Flies were infected once on a parasitaemic rat. Teneral flies, both sexes indiscriminate, showed a procyclic and(More)
Two successive experiments were carried out in which three cows were treated by intramuscular injection of either 0.5 mg/kg isometamidium or 1 mg/kg ethidium and compared with another group of three cows which received a subcutaneously implanted sustained release device (SRD) containing the same dose of drug. The prophylactic effect of both drug(More)
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(More)
This report presents an experimental study of the life cycle of Trypanosoma congolense (ZRE/G 143/90) in relation to the vectorial competence of Glossina morsitans (Mall). The rate of engorgement at the time of an infectious meal and the mortality before day 15 of the life cycle were not significantly different between male and female flies. The mesocyclic(More)
Two methods of salivation of tsetse flies, namely manual salivation and method of Bruce et al. were simultaneously evaluated on 1,702 male uninfected Glossina palpalis palpalis (Zaire), G. palpalis gambiensis (Bobo-Dioulasso), G. p. gambiensis (Maisons-Alfort) et G. morsitans morsitans (Mall) fasted for 23, 48 and 72 hours. The risk of salivation was 0.66(More)
Non-teneral tsetse flies of Glossina morsitans morsitans (strain Mall) about 16 days old were fed, once, on a rat infected by Trypanosoma congolense IL 1180. The global vectorial competence (VC) of these flies was appraised at 0.1035. VC in males was more important than for females. Infection by mesoprocyclic index was greater in female flies than in male(More)
The purpose of this work was to assess the influence of several healthy meals (0, 1 and 2) prior to the infectious one on the vectorial competence of Glossina morsitans morsitans (Mall). The teneral flies (< 32 h old) of this line were divided into three groups. The tsetse flies of group A received no meal. The ones of group B received one healthy meal on(More)
Two groups of teneral flies (aged less than 32 hours) of Glossina morsitans morsitans (Mall) were fed separately on two rats that had been infected with Trypanosoma (Nannomonas) congolense IL 1180, among which one had a low parasitaemia (antilog 5.4-5.7) and the other a high parasitaemia (antilog 7.8-8.1). Following to the two modes of parasitaemia,(More)
The vectorial competence (VC) of teneral (less than 32 h) Glossina tachinoides Westwood and G. palpalis gambiensis Vanderplank, fed simultaneously on a guinea-pig infected with Trypanosoma brucei brucei EATRO 1125, was assessed. Statistical analysis of the experimental results revealed that female G. tachinoides had a significantly higher midgut infection(More)
