Journal ArticleDOI
A study on African animal trypanosomosis in four areas of Senegal
TL;DR: A high risk of infection in dogs with T. congolense savannah-type was shown in Sine Saloum, requiring prevention and control of dogs in this area, and the involvement of tsetse flies in the transmission of T. CONGolense is discussed.
Journal ArticleDOI
Detecting Wahlund effects together with amplification problems: Cryptic species, null alleles and short allele dominance in Glossina pallidipes populations from Tanzania.
Oliver Manangwa,Thierry De Meeûs,Pascal Grébaut,Adeline Ségard,Mechtilda Byamungu,Sophie Ravel +5 more
TL;DR: The coexistence of two highly divergent cryptic clades in the same sites is unveiled and separated analyses of the two clades suggest very small tsetse densities and relatively large dispersal.
Journal ArticleDOI
RNA-seq de novo Assembly Reveals Differential Gene Expression in Glossina palpalis gambiensis Infected with Trypanosoma brucei gambiense vs. Non-Infected and Self-Cured Flies.
Illiassou Hamidou Soumana,Christophe Klopp,Sophie Ravel,Ibouniyamine Nabihoudine,Bernadette Tchicaya,Hugues Parrinello,Luc Abate,Stéphanie Rialle,Anne Geiger +8 more
TL;DR: The results provide new means to decipher fly infection mechanisms, crucial to develop anti-vector control strategies, and the possible roles of several DEGs regarding fly susceptibility and refractoriness are discussed.
Journal ArticleDOI
X-chromosome mapping experiments suggest occurrence of cryptic species in the tsetse fly Glossina palpalis palpalis
TL;DR: Using flies from colonies of Glossina palPalis palpalis (Robineau-Desvoidy, 1830) that originated in Nigeria and Bas-Zaire, the two microsatellite loci Gpg19.62 and Gpg55.3 have been added to the X-chromosome map, thus increasing to seven the number of loci mapped on that chromosome.
Journal ArticleDOI
Population structuring of the tsetse Glossina tachinoides resulting from landscape fragmentation in the Mouhoun River basin, Burkina Faso.
Naférima Koné,T. De Meeûs,Jérémy Bouyer,Sophie Ravel,Laure Guerrini,Eliézer K. N’Goran,L. Vial +6 more
TL;DR: The impact of landscape fragmentation resulting from human‐ and climate‐mediated factors on the structure of a population of Glossina tachinoides Westwood (Diptera: Glossinidae) in the Mouhoun River basin, Burkina Faso, was investigated.
