Estimating <em>Plasmodium falciparum</em> transmission rates in low-endemic settings using a combination of community prevalence and health facility... (Publications)
As some malaria control programs shift focus from disease control to transmission reduction, there is a need for transmission data to monitor progress. At lower levels of transmission, it becomes increasingly [...] studies. Many programs conduct regular cross sectional parasite prevalence surveys, and have access to malaria treatment data routinely collected by ministries of health, often in health management information
Prodrugs of reverse fosmidomycin analogues (Publications)
biosynthesis that is essential in Plasmodium falciparum. The drug has been used successfully to treat malaria patients in clinical studies, thus validating IspC as an antimalarial target. However, improvement [...] compounds were also tested for their cytotoxicity toward HeLa cells and in vivo in a Plasmodium berghei malaria model as well as in the SCID mouse P. falciparum model
Adherence to and acceptability of artemether-lumefantrine as first-line anti-malarial treatment: evidence from a rural community in Tanzania (Publications)
six-dose regimen of artemether-lumefantrine (AL) therapy for uncomplicated Plasmodium falciparum malaria results in cure rates > 95% with good tolerability. MATERIALS AND METHODS: A prospective study was [...] the context of the ALIVE study, a prospective, community-based, observational study in a rural, malaria-endemic area of Tanzania. Following microscopic confirmation of P. falciparum infection, the first
A novel multiple-stage antimalarial agent that inhibits protein synthesis (Publications)
There is an urgent need for new drugs to treat malaria, with broad therapeutic potential and novel modes of action, to widen the scope of treatment and to overcome emerging drug resistance. Here we describe [...] blocking and chemoprotection. DDD107498 was developed from a screening programme against blood-stage malaria parasites; its molecular target has been identified as translation elongation factor 2 (eEF2), which
Discovery and characterization of ACT-451840: an antimalarial drug with a novel mechanism of action (Publications)
More than 40 % of the world's population is at risk of being infected with malaria. Most malaria cases occur in the countries of sub-Saharan Africa, Central and South America, and Asia. Resistance to standard
Identification of 2,4-disubstituted imidazopyridines as hemozoin formation inhibitors with fast-killing kinetics and <em>in vivo</em> efficacy in the... (Publications)
SoftFocus Kinase library, was identified from a high throughput phenotypic screen against the human malaria parasite Plasmodium falciparum. Hit compounds showed moderate asexual blood stage activity. During [...] Frontrunner compound 37 showed good exposure in mice combined with good in vitro activity against the malaria parasite, which translated into in vivo efficacy in the P. falciparum NOD-scid IL-2Rgamma(null) (NSG)
Imaging of <em>Plasmodium</em> liver stages to drive next-generation antimalarial drug discovery (Publications)
Most malaria drug development focuses on parasite stages detected in red blood cells, even though to achieve eradication, next-generation drugs active against both erythrocytic and exo-erythrocytic forms [...] imidazolopiperazine confers complete causal prophylactic protection (15 mg/kg) in rodent models of malaria and shows potent in vivo blood-stage therapeutic activity. The open source chemical tools resulting
Micro-epidemiological structuring of <em>Plasmodium falciparum</em> parasite populations in regions with varying transmission intensities in Africa (Publications)
Background: The first models of malaria transmission assumed a completely mixed and homogeneous population of parasites. Recent models include spatial heterogeneity and variably mixed populations. However [...] pairs is predicted by relatedness in space and time. Conclusions: Our findings suggest that targeted malaria control will benefit the surrounding community, but unfortunately also that emerging drug resistance
Spatial and temporal characteristics of laboratory-induced <em>Anopheles coluzzii</em> swarms: shape, structure, and flight kinematics (Publications)
Malaria mosquitoes mate in swarms, but how these swarms are formed and maintained remains poorly understood. We characterized three-dimensional spatiotemporal flight kinematics of Anopheles coluzzii males [...] results in the observed elliptical cone swarm shape. We discuss the implications of these finding on malaria mosquito mating success, speciation and for vector control. © 2024 The Author(s)
Asymptomatic <em>Plasmodium</em> infection and glycemic control in adults: results from a population-based survey in south-central Côte d'Ivoire (Publications)
associations of Plasmodium infection (PI) with fasting glucose (FG) and glycated hemoglobin (HbA1c) in malaria-endemic south-central Cote d'Ivoire. METHODS: We studied 979 participants (non-pregnant; no treated [...] Fasting venous blood was obtained for PI, FG, and HbA1c assessment. We defined PI as a positive malaria rapid diagnostic test (RDT) or microscopic identification of Plasmodium species. We applied multivariable [...] diagnosis in the presence of asymptomatic PI may misclassify or...
