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...

Recalculating the net use gap: a multi-country comparison of ITN use versus ITN access (Publications)
treated nets is widely recognized as one of the main interventions to prevent malaria and high use rates are a central goal of malaria programs. The gap between household ownership of at least one ITN and population [...] within the household' as now recommended by Roll Back Malaria and the World Health Organization. Data from 41 Demographic Health Surveys (DHS) and Malaria Indicator Surveys (MIS) (2005-2012) in sub-Saharan
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...
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...
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....

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...
Artemisinins and synthetic trioxolanes in the treatment of helminth infections (Publications)
following recommended malaria treatment schedules, found an effect against schistosomiasis. SUMMARY: Artemisinin-based combination therapies are increasingly deployed against malaria, and hence there is [...] that artemisinin-based combination therapy might have on trematode infections in settings where malaria and helminthiases are co-endemic. RECENT FINDINGS: The artemisinins and synthetic trioxolanes possess
