Transcription profiling of a recently colonised pyrethroid resistant <em>Anopheles gambiae</em> strain from Ghana (Publications)
resistance to the pyrethroid insecticides used to treat bednets threatens the sustainability of malaria control in sub-Saharan Africa. While the impact of target site insensitivity alleles is being widely [...] detoxification--though equally important--remains elusive. The successful development of new tools for malaria intervention and management requires a comprehensive understanding of insecticide resistance, including
Multiplicity of <em>Plasmodium falciparum</em> infection following intermittent preventive treatment in infants (Publications)
Intermittent preventive treatment in infants with sulphadoxine-pyrimethamine (IPTi-SP) reduces malaria morbidity by 20% to 33%. Potentially, however, this intervention may compromise the acquisition of [...] of polyclonal infections (69.6% vs. 69.7%; P = 0.99). Adjusting for study site, current and prior malaria, parasite density, and season did not change this finding. CONCLUSIONS: IPTi-SP appears to have no

anti-plasmodial activity, and reduced toxicity compared to other artemisinins in clinical use against malaria. We infected adult mice by subcutaneous injection of S. mansoni cercariae (about 200) and treated [...] release of the artemisone that was verified in vivo and in vitro bioassays using drug-sensitive malaria parasites. We found superior strong anti-schistosome effects up to a total reduction of worm number
<em>Plasmodium vivax</em> and <em>Plasmodium falciparum</em> infection dynamics: re-infections, recrudescences and relapses (Publications)
BACKGROUND: In malaria endemic populations, complex patterns of Plasmodium vivax and Plasmodium falciparum blood-stage infection dynamics may be observed. Genotyping samples from longitudinal cohort studies [...] CONCLUSION: The statistical model developed here provides a useful new tool for in-depth analysis of malaria data from longitudinal cohort studies, and future application to data sets with multi-locus genotyping

In an agricultural area of Southern Cote d'Ivoire, the main malaria vector Anopheles coluzzii shows multiple resistance across insecticides mediated by both target site [...] mutation in Cote d'Ivoire, and as in other populations, it is found in both dominant West African malaria vector species. Continued monitoring of N1575Y is underway, as are studies to elucidate its contribution
