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
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....
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...
Analysis of diagnostic findings from the European mobile laboratory in Gueckedou, Guinea, March 2014 through March 2015 (Publications)
2015. METHODS: The unit diagnosed EVD and malaria, using the RealStar Filovirus Screen reverse transcription-polymerase chain reaction (RT-PCR) kit and a malaria rapid diagnostic test, respectively. RESULTS:
Comparison of analytical methods for the evaluation of antibody responses against epitopes of polymorphic protein antigens (Publications)
Surface exposed protein antigens of the malaria parasite Plasmodium falciparum frequently harbor multiple dimorphic amino acid positions. These are associated with parasite immune evasion and represent [...] the humoral immune response against a semiconserved sequence (YX(44)LFX(47)KEKMX(52)L) of the key malaria blood stage vaccine candidate merozoite surface protein-1 (MSP-1). Monoclonal antibodies (mAbs) raised [...] MSP-1(43-53) variant sequences. When used for the evaluation of humoral...
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
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...
Ethnobotanical study of some of mosquito repellent plants in north-eastern Tanzania (Publications)
potential for malaria vector control requires evaluation in areas with different level of malaria endemicity. The essential oils of Ocimum suave and Ocimum kilimandscharicum were evaluated against malaria vectors [...] filter papers impregnated with Ocimum extracts, knockdown effects and mortality was investigated on malaria mosquito Anopheles arabiensis and Anopheles gambiae, including a nuisance mosquito, Culex quinqu
Modelling the impact of insecticide-based control interventions on the evolution of insecticide resistance and disease transmission (Publications)

It is based on a classic Ross-Macdonald derivation of the malaria basic reproductive number (R0) and may be used to assess [...] (iv) the impact of resistance once it has arisen and, in particular, whether it is sufficient for malaria transmission to resume. The model consists of a system of difference equations that tracks the immature [...] and easily generalizable to many scenarios using different calibrations...
