Effects of vector-control interventions on changes in risk of malaria parasiotaemia in sub-Saharan Africa: a spatial and temporal analysis (Publications)
episodes and deaths due to malaria have been mainly associated with the expansion of vector-control measures, such as insecticide-treated bednets and indoor residual spraying. Malaria indicator surveys gather [...] gather information about key malaria indicators through national representative household surveys. We aimed to estimate changes in risk of malaria parasitaemia at high spatial resolution in sub-Saharan Africa [...] that had publicly available data from two malaria indicator or...
Metabolic profiling framework for discovery of candidate diagnostic markers of malaria (Publications)
Despite immense efforts to combat malaria in tropical and sub-tropical regions, the potency of this vector-borne disease and its status as a major driver of morbidity and mortality remain undisputed. We
Multiple insecticide resistance in <em>Anopheles gambiae</em> from Tanzania: a major concern for malaria vector control (Publications)
development of insecticide resistance in the major malaria vectors. This study was carried out to monitor the susceptibility status of major malaria vectors to insecticides used for IRS and LLINs in mainland [...] BACKGROUND: Malaria vector control in Tanzania is based on use of long-lasting insecticide treated nets (LLINs) and indoor residual spraying (IRS), which both rely on the use of chemical insecticides. [...] An. gambiae sensu stricto (s.s.) Kisumu strain. RESULTS: Anopheles arabiensis...
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)
component, related mappable malaria metrics are also described which may be measured and evaluated by malaria programmes seeking to better understand the determinants of malaria risk. 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...
