Journal ArticleDOI
Bidirectional introgressive hybridization between a cattle and human schistosome species.
Tine Huyse,Tine Huyse,Bonnie L. Webster,Sarah Geldof,J. Russell Stothard,Oumar T. Diaw,Katja Polman,David Rollinson +7 more
TL;DR: In this article, nuclear and mitochondrial markers revealed unexpected natural interactions between a bovine and human Schistosoma species: S. bovis and S. haematobium.
Journal ArticleDOI
Introgressive Hybridization of Schistosoma haematobium Group Species in Senegal: Species Barrier Break Down between Ruminant and Human Schistosomes
TL;DR: These data provide indisputable evidence for: the high occurrence of bidirectional hybridization between these Schistosoma species; the first conclusive evidence for the natural hybridisation between S. haematobium and S. curassoni; and demonstrate that the transmission of the different species and their hybrids appears focal.
Journal ArticleDOI
Praziquantel treatment of school children from single and mixed infection foci of intestinal and urogenital schistosomiasis along the Senegal River Basin: monitoring treatment success and re-infection patterns.
Bonnie L. Webster,Oumar T. Diaw,Mohmoudane M. Seye,Djibril S. Faye,J. Russell Stothard,José Carlos Sousa-Figueiredo,José Carlos Sousa-Figueiredo,José Carlos Sousa-Figueiredo,David Rollinson +8 more
TL;DR: The data show that high and rapid re-infection rates occur, especially for S. mansoni, within a six-month period following treatment, and new treatment regimes should be designed and implemented to control schistosomiasis in the school-age population.
Journal ArticleDOI
Genetic diversity within Schistosoma haematobium: DNA barcoding reveals two distinct groups.
Bonnie L. Webster,Aiden M. Emery,Joanne P. Webster,Anouk N. Gouvras,Amadou Garba,Oumar T. Diaw,Mohmoudane M. Seye,Louis Albert Tchuem Tchuenté,Christopher Simoonga,Joseph R. Mwanga,Charles N. Lange,Curtis Kariuki,Khalfan A. Mohammed,J. Russell Stothard,David Rollinson +14 more
TL;DR: The high occurrence of the haplotype (H1) suggests that at some point in the recent evolutionary history of S. haematobium in Africa the population may have passed through a genetic ‘bottleneck’ followed by a population expansion.
Journal ArticleDOI
DNA ‘barcoding’ of Schistosoma mansoni across sub-Saharan Africa supports substantial within locality diversity and geographical separation of genotypes
Bonnie L. Webster,Joanne P. Webster,Anouk N. Gouvras,Amadou Garba,Mariama S. Lamine,Oumar T. Diaw,Mohmoudane M. Seye,Louis-Albert Tchuem Tchuenté,Christopher Simoonga,Likezo Mubila,Joseph R. Mwanga,Nicholas J.S. Lwambo,Narcis B. Kabatereine,Charles N. Lange,Curtis Kariuki,Gerald M. Mkoji,David Rollinson,J. Russell Stothard +17 more
TL;DR: DNA 'barcoding' approach is taken using sequence analysis of a 450bp region within the mitochondrial cox1 gene to assess the genetic diversity within a large number of S. mansoni larval stages collected from their natural human hosts across sub-Saharan Africa.
