Emergence of FY*A(null) in a <em>Plasmodium vivax</em>-endemic region of Papua New Guinea (Publications)
Human genetic polymorphisms of this nature are common in malarious regions, and all four human malaria parasites are holoendemic below 1500 meters in PNG. At this elevation, a prominent condition cha [...] demonstrated that alpha(+)-thalassemia is associated with increased susceptibility to uncomplicated malaria among young children. It is further proposed that alpha(+)-thalassemia may facilitate so- called [...] vivax infection to act later in life as a "natural vaccine" against severe...
Spatial mapping and prediction of <em>Plasmodium falciparum</em> infection risk among school-aged children in Côte d'Ivoire (Publications)
school-aged children in Cote d'Ivoire represent the most up-to-date malaria risk maps. These tools can be used for spatial targeting of malaria control interventions. [...] BACKGROUND: In Cote d'Ivoire, malaria remains a major public health issue, and thus a priority to be tackled. The aim of this study was to identify spatially explicit indicators of Plasmodium falciparum [...] ownership and household characteristics. Children were interviewed for preventive measures against malaria....
Leptospira seroprevalence and risk factors in health centre patients in Hoima District, Western Uganda (Publications)
consented participants. Overall, 69% reported having fever in the past year, with 49% reporting malaria, 14% malaria relapse, 6% typhoid fever, 3% brucellosis, and 0% leptospirosis. We tested sera by microscopic [...] Nigeria (serogroup Pyrogenes). Probable recent leptospirosis was associated with having self-reported malaria within the past year (p = 0.048). Higher risk activities included skinning cattle (n = 6) with 12 [...] serogroup). Leptospirosis should be a diagnostic consideration in...
Visual Analysis of Long Lasting Insecticidal Nets to Maximise Universal Access (Projects)

vital in reducing the malaria burden among children over the last 20 years. Reductions have stagnated and resources available for control are half what is needed to meet malaria control milestones. Standard [...] between products, influencing their value-for-money. This project will deliver information to National Malaria Control Programs (NMCP) that enables them to 1) select durable and cost-effective LLINs to buy, 2) [...] NMCP=medium to select the best LLINs for their setting to optimize the...
Molecular epidemiology and seroprevalence in asymptomatic <em>Plasmodium falciparum</em> infections of Malagasy pregnant women in the highlands (Publications)
BACKGROUND: Malaria epidemiology in Madagascar is classified into four different areas, ranging from unstable seasonal transmission in the highlands to hyperendemic perennial transmission areas in the [...] the costal level. Most malaria studies in Madagascar are focused on symptomatic children. However, because of the low transmission in some areas with correspondingly low level of semi-immunity, adults are [...] genetic epidemiology of malarial infections in pregnant women in order to provide...
A review of the frequencies of <em>Plasmodium falciparum</em> Kelch 13 artemisinin resistance mutations in Africa (Publications)

A rise in the frequency of these mutations and [...] Plasmodium falciparum Kelch 13 (Pfk13), 7 years ago has provided an invaluable tool for monitoring AR in malaria endemic countries. Molecular Pfk13 surveillance revealed the resistance foci in the Greater Mekong [...] and their spread would reverse the gains made in the reduction of malar...
Comparative efficacy of Vector Guard® to Olyset® Plus insecticide-treated nets against strongly pyrethroid-resistant <em>Anopheles arabiensis</em> in... (Publications)
promising pyrethroid–PBO ITN for the control of resistant malaria vectors. The addition of Vector Guard® to the class of pyrethroid–PBO ITNs will enable malaria control programs to select cost-effective ITNs, improving [...] Introduction: The resistance of malaria vectors to pyrethroids has compromised the efficacy of pyrethroid insecticide-treated nets (ITNs). In response, ITNs with pyrethroids and piperonyl butoxide (PBO) [...] conducted to evaluate Vector Guard® relative to Olyset® Plus (a...

Next generation chemiluminescent probes for antimalarial drug discovery (Publications)
Malaria is caused by parasites of the Plasmodium genus and remains one of the most pressing human health problems. The spread of parasites resistant to or partially resistant to single or multiple drugs [...] frontline antimalarial artemisinin and its derivatives, poses a serious threat to current and future malaria control efforts. In vitro drug assays are important for identifying new antimalarial compounds and [...] detection limit of less than 100 parasites of the presented biosensor system...
