Novel antimalarial tetrazoles and amides active against the hemoglobin degradation pathway in <em>Plasmodium falciparum</em> (Publications)
Malaria control programs continue to be threatened by drug resistance. To identify new antimalarials, we conducted a phenotypic screen and identified a novel tetrazole-based series that shows fast-kill [...] polymerization pathway and that can form the basis of future optimization efforts to develop a new malaria treatment.
VectorDisk: a microfluidic platform integrating diagnostic markers for evidence-based mosquito control (Publications)
identify mosquito and malaria parasite species as well as insecticide resistance mechanisms. In the second study, purified nucleic acids served as samples to test arboviral and malaria infective mosquito
Discovery and characterization of potent, efficacious, orally available antimalarial plasmepsin X inhibitors and preclinical safety assessment of... (Publications)
Plasmepsin X (PMX) is an essential aspartyl protease controlling malaria parasite egress and invasion of erythrocytes, development of functional liver merozoites (prophylactic activity), and blocking [...] days. This work demonstrates the potential to deliver PMX inhibitors with in vivo efficacy to treat malaria.
Multiplexed ddPCR-amplicon sequencing reveals isolated <em>Plasmodium falciparum</em> populations amenable to local elimination in Zanzibar, Tanzania (Publications)
Zanzibar has made significant progress toward malaria elimination, but recent stagnation requires novel approaches. We developed a highly multiplexed droplet digital PCR (ddPCR)-based amplicon sequencing [...] genetic structure across the Zanzibar archipelago and provides actionable insights for prioritizing malaria elimination efforts.
Structure-activity relationships and antiplasmodial potencies of novel 3,4-disubstituted 1,2,5-oxadiazoles (Publications)
The 4-substituted 3-amino-1,2,5-oxadiazole 1 from the Malaria Box Project of the Medicines for Malaria Venture foundation shows very promising selectivity and in vitro activity against Plasmodium falciparum
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
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
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
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
Etiology of anemia among infants, school-aged children, and young non-pregnant women in different settings of south-central Côte d'Ivoire (Publications)
samples were subjected to standardized quality-controlled methods. We found high prevalence of anemia, malaria, inflammation, and deficiencies of iron, riboflavin, and vitamin A but low prevalence and intensities [...] factor for anemia in non-pregnant women. Our findings call for interventions to protect infants from malaria, improved intake of dietary iron, and given the importance of anemia of inflammation in school-aged
