Comparative analysis of two methods for measuring sales volumes during malaria medicine outlet surveys (Publications)
BACKGROUND: There is increased interest in using commercial providers for improving access to quality malaria treatment. Understanding their current role is an essential first step, notably in terms of the volume [...] methods. METHODS: Using sales volume data on anti-malarials and rapid diagnostic tests (RDTs) for malaria collected through provider recall (RC) and retail audits (RA), this study measures the degree of
Longitudinal estimation of <em>Plasmodium falciparum </em>prevalence in relation to malaria prevention measures in six sub-Saharan African countries (Publications)
(PfPR) is a widely used metric for assessing malaria transmission intensity. This study was carried out concurrently with the RTS,S/AS01 candidate malaria vaccine Phase III trial and estimated PfPR over [...] 3 sites. Surveys were usually performed during the peak malaria parasite transmission season, in one home visit, when medical history and malaria risk factors/prevention measures were collected, and a blood [...] 0.52, 0.68, 0.41) and bed net use in 2 surveys (ORs: 0.63, 0.68, 1.03, 1.78)...
Lysophosphatidylcholine regulates sexual stage differentiation in the human malaria parasite <em>Plasmodium falciparum</em> (Publications)
bottleneck in the Plasmodium life cycle and a key intervention target of ongoing efforts to eradicate malaria. Sexual differentiation is essential for this process, as only sexual parasites, called gametocytes [...] activation of sexual-stage-specific transcription and gametocyte formation. Our results reveal that malaria parasites can sense and process host-derived physiological signals to regulate differentiation. These [...] of the sexual differentiation pathway in Plasmodium that may provide...
Mapping multiple components of malaria risk for improved targeting of elimination interventions (Publications)

Implementing tailored [...] There is a long history of considering the constituent components of malaria risk and the malaria transmission cycle via the use of mathematical models, yet strategic planning in endemic countries tends [...] tends not to take full advantage of available disease intelligence to tailor...
The ethics of health care delivery in a pediatric malaria vaccine trial: the perspectives of stakeholders from Ghana and Tanzania (Publications)
care to participants and communities of low-resource settings involved in a Phase II/III pediatric malaria vaccine trial (PMVT). We conducted 52 key informant interviews with major stakeholders of an int
Development of amplicon deep sequencing markers and data analysis pipeline for genotyping multi-clonal malaria infections (Publications)
BACKGROUND: Amplicon deep sequencing permits sensitive detection of minority clones and improves discriminatory power for genotyping multi-clone Plasmodium falciparum infections. New amplicon sequenci

Fortunately [...] performed for the main three malaria vectors in sub-Saharan Africa, Anopheles gambiae s.s, An. arabiensis and An. funestus. We considered areas having low, moderate and high malaria transmission, corresponding [...] however, there is growing evidence and consensus that effective...
