Wild fauna as a probable animal reservoir for Trypanosoma brucei gambiense in Cameroon.
Blood was collected from wild animals in three human African trypanosomiasis foci and from a nonendemic control area to study the existence of a wild animal reservoir for Trypanosoma brucei gambiense in South Cameroon. Expand
[The trapping of tsetse flies (Diptera: Glossinidae). Improvement of a model: the Vavoua trap].
A new model of trap is proposed, the "Vavoua" trap, issued from the biconical and the pyramidal traps, with a similar efficiency but a twice lower cost, to consider its use for large-scale control of tsetse flies in the forest zones by rural communities. Expand
Multiple trypanosome infections in wild tsetse in Côte d'Ivoire detected by PCR analysis and DNA probes.
There was no obvious association between the different species of flies and the infecting trypanosomes, and a large proportion (97%) of the probed midguts were shown to contain Kilifi T. godfreyi infections. Expand
A high prevalence of mixed trypanosome infections in tsetse flies in Sinfra, Côte d'Ivoire, detected by DNA amplification.
It is demonstrated that PCR facilitates the easy identification of maturetrypanosome infections in tsetse, providing a reliable estimation of trypanosomiasis challenge. Expand
Characterization of Trypanosoma brucei s.l. infecting asymptomatic sleeping-sickness patients in Côte d'Ivoire: a new genetic group?
Six villagers in the Sinfra focus of sleeping sickness in Côte d'Ivoire who in 1995 were asymptomatic and refusing treatment, despite then being serologically and parasitologically positive for trypanosomes, were followed-up until 2002, when all six cases were infected with a 'new' distinct genetic group of T. brucei s.l. b.

Measurement of risk in endemic areas of human African trypanosomiasis in Côte d'Ivoire.
An index of epidemiological risk was developed for the foci of human African trypanosomiasis (HAT) in the forest zone of Côte d'Ivoire, based on the following characteristics of Glossina palpalisExpand
Infection rate of Trypanosoma brucei s.l., T. vivax, T. congolense "forest type", and T. simiae in small wild vertebrates in south Cameroon.
This study showed that trypanosomes of the subgenera Duttonella, Nannomonas and Trypanozoon could infect small wild vertebrates as has been shown for large ungulates and carnivores. Expand
Influence of habitat and seasonal variation on wild mammal diversity and distribution with special reference to the Trypanosoma brucei gambiense host-reservoir in Bipindi (Cameroon).
Variations in the influence of habitat and seasonal variations on the diversity and spatial distribution of wild mammals in Bipindi indicate a permanent movement of wild mammal reservoir or feeding hosts from one biotope to another over the seasons. Expand
Untreated Human Infections by Trypanosoma brucei gambiense Are Not 100% Fatal
It is demonstrated that a number of human African trypanosomiasis patients from the Ivory Coast display such infection courses, recognising that trypanotolerance exists in humans, as is now widely accepted for animals, is a major step forward for future research in the field of HAT. Expand
Follow‐up of Card Agglutination Trypanosomiasis Test (CATT) positive but apparently aparasitaemic individuals in Côte d'Ivoire: evidence for a complex and heterogeneous population
The stability of seropositivity and the pattern of results obtained with both immunological and parasitological examinations support the view that individual factors, such as immune response to infection, might be involved in the isolated CATT positivity phenomenon. Expand
