Spatial distribution of the chromosomal forms of <em>anopheles gambiae</em> in Mali (Publications)
BACKGROUND: Maps of the distribution of malaria vectors are useful tools for stratification of malaria risk and for selective vector control strategies. Although the distribution of members of the Anopheles [...] (insecticide resistance management) and may serve as a decision support tool for the basis for future malaria control strategies including genetically manipulated mosquitoes
Comparative study of the effects of artemether and artesunate on juvenile and adult<em> Schistosoma mansoni</em> in experimentally infected mice (Publications)
stages of schistosome parasites. Since artemisinin derivatives will be increasingly used to treat malaria, it is important to study the effects of 7-day monotherapy regimens on schistosome infections. We [...] artemether or artesunate at various doses and regimens including those currently used for monotherapy of malaria. Three doses of artemether, at concentrations of 150 or 300 mg/kg, administered to mice with juvenile [...] discussions on the effect and use of artemisinin derivatives against...
The mode of action of spatial repellents and their impact on vectorial capacity of<em> Anopheles gambiae sensu stricto</em> (Publications)
Malaria vector control relies on toxicity of insecticides used in long lasting insecticide treated nets and indoor residual spraying. This is despite evidence that sub-lethal insecticides reduce human-vector [...] human-vector contact and malaria transmission. The impact of sub-lethal insecticides on host seeking and blood feeding of mosquitoes was measured. Taxis boxes distinguished between repellency and attraction [...] target product profiles of spatial repellent products that can be used to...
Case studies in public-private-partnership in health with the focus of enhancing the accessibility of health interventions (Publications)
level NGO consortium with a focus on malaria and the second one is an international advocacy group with an overarching goal of protecting children against malaria through an innovative mechanism. The case [...] case study approach is used to analyze why the PPP approach was used to address malaria control and how it was implemented. Both PPPs demonstrated that relationships between the public and private sector
Spatial effects of mosquito bednets on child mortality (Publications)
Insecticide treated nets (ITN) have been proven to be an effective tool in reducing the burden of malaria. Few randomized clinical trials examined the spatial effect of ITNs on child mortality at a high [...] coverage. We analyzed for the first time data from a large follow-up study in an area of high perennial malaria transmission in southern Tanzania to describe the spatial effects of bednets on all-cause child mortality [...] with insecticide, and (2) the relative homogeneity of coverage with...
Ecohealth approach to urban waste management: exposure to environmental pollutants and health risks in Yamoussoukro, Côte d'Ivoire (Publications)
standards of surface water quality. Questionnaire results showed that malaria was the most commonly reported disease. Diarrhoea and malaria were associated with poor sanitation. Households having dry latrines [...] confidence interval (CI) 1.2-2.7) compared to latrines with septic tanks and also a higher risk for malaria (OR = 1.9, 95% (CI) 1.1-3.3). Our research showed that combining health and environmental assessments
Semi-field evaluation of a volatile transfluthrin-based intervention reveals efficacy as a spatial repellent and evidence of other modes of action (Publications)
Presently, the most common malaria control tools-i.e., long lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS)-are limited to targeting indoor biting and resting behaviors of Anopheles [...] Anopheles mosquito species. Few interventions are targeted towards malaria control in areas where transmission is driven or persists due to outdoor biting behaviors. This study investigated a volatile [...] Southern Province, Zambia, is one such environment where outdoor biting is...
Spatial epidemiology of urban health risks in select West African cities (Publications)
epidemiology of diarrhaea and malaria, and their associated risks factors in the following select West African cities. Spatial variability of exposure to diarrhaea and malaria transmission is linked to several
Case report: Diagnostic challenges in the detection of a mixed <em>Plasmodium vivax/ovale</em> infection in a non-endemic setting (Publications)
In clinical practice, mixed-species malaria infections are often not detected by light microscopy (LM) or rapid diagnostic test, as a low number of parasites of one species may occur. Here, we report the [...] This case demonstrates the significance of molecular testing in the detection of mixed-species malaria infections and highlights the importance of a detailed data analysis during the medical validation
Synthesis and pharmacological evaluation of fluorescent and photoactivatable analogues of antiplasmodial naphthylisoquinolines (Publications)
antiplasmodial activities in vitro and in vivo, even against chloroquine-resistant strains of the malaria pathogen. For the directed optimization of these activities, an investigation of the mode of action [...] their pharmacological potential as a valuable lead structure against the widespread tropical disease malaria
