| the population structure of glossina palpalis gambiensis from island and continental locations in coastal guinea. | we undertook a population genetics analysis of the tsetse fly glossina palpalis gambiensis, a major vector of sleeping sickness in west africa, using microsatellite and mitochondrial dna markers. our aims were to estimate effective population size and the degree of isolation between coastal sites on the mainland of guinea and loos islands. the sampling locations encompassed dubréka, the area with the highest human african trypanosomosis (hat) prevalence in west africa, mangrove and savannah site ... | 2009 | 19290038 |
| tsetse elimination: its interest and feasibility in the historical sleeping sickness focus of loos islands, guinea. | guinea is the west african country which is currently the most prevalent for sleeping sickness. the littoral area is the region where most of the recent sleeping sickness cases have been described, especially the mangrove sleeping sickness foci of dubreka and boffa where glossina palpalis gambiensis is the vector. loos islands constitute a small archipelago 5 km apart from the capital, conakry. medical, animal, and entomological surveys were implemented in these islands in oct-nov 2006. no patho ... | 2009 | 19353949 |
| genetic and morphometric evidence for population isolation of glossina palpalis gambiensis (diptera: glossinidae) on the loos islands, guinea. | allele frequencies at four microsatellite loci, and morphometric features based on 11 wing landmarks, were compared among three populations of glossina palpalis gambiensis (diptera: glossinidae) in guinea. one population originated from the loos islands separated from the capital conakry by 5 km of sea, and the two others originated from the continental mangrove area close to dubreka, these two groups being separated by approximately 30 km. microsatellites and wing geometry data both converged t ... | 2006 | 17017219 |
