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)

Malaria is a widespread disease known to affect hundreds of millions of people and presents a perceivable [...] polar oxygen and amidine substituents and the hydrophobic linking chain for the activity against malaria
Delayed anemia after treatment with injectable artesunate in the democratic republic of the Congo: a manageable issue (Publications)
treatment of severe malaria. A total of 350 patients (215 [61.4%] < 5 years of age and 135 [38.6%] > /= 5 years of age) were followed-up after treatment with injectable artesunate for severe malaria in hospitals
Probing <em>Plasmodium falciparum</em> sexual commitment at the single-cell level (Publications)
Background: Malaria parasites go through major transitions during their complex life cycle, yet the underlying differentiation pathways remain obscure. Here we apply single cell transcriptomics to unravel [...] programs, with important implications for our understanding of parasite biology and the ongoing malaria elimination campaign.
High sensitivity detection of <em>Plasmodium</em> species reveals positive correlations between infections of different species, shifts in age... (Publications)
molecular diagnosis reveals patterns of malaria risk that are significantly different from those obtained by standard LM. Results provide insight relevant to design of malaria control and eradication strategies [...] BACKGROUND: When diagnosed by standard light microscopy (LM), malaria prevalence can vary significantly between sites, even at local scale, and mixed species infections are consistently less common than [...] high-throughput molecular species diagnostic assay now enables routine...
Socially-marketed rapid diagnostic tests and ACT in the private sector: ten years of experience in Cambodia (Publications)
some populations have recently experienced dramatic declines in malaria, the majority of those most at risk of Plasmodium falciparum malaria still lack access to effective treatment with artemisinin combination [...] which, in many countries, plays an important role in the provision of malaria treatment. The Affordable Medicines Facility for malaria (AMFm) is a recent initiative that aims to increase the provision of
Association between the proportion of <em>Plasmodium falciparum</em> and <em>Plasmodium vivax</em> infections detected by passive surveillance and the... (Publications)
proportion of infections detected in routine malaria data, P(Detect), was derived from paired household cross-sectional survey and routinely collected malaria data within health facilities. P(Detect) was [...] BACKGROUND: Passively collected malaria case data are the foundation for public health decision making. However, because of population-level immunity, infections might not always be sufficiently symptomatic [...] model in 431 clusters spanning the Americas, Africa, and Asia. The...
Dengue fever in Dar es Salaam, Tanzania: clinical features and outcome in populations of black and non-black racial category (Publications)
are under-reported in Africa and often mistaken for malaria. These results highlight the need to introduce point-of-care tests, beside the one for malaria, to detect outbreaks and orientate diagnosis. TRIAL [...] clinical presentation, including warning signs, was assessed by logistic regression adjusted for age, malaria coinfection, secondary dengue and duration of symptoms at inclusion. The independent association [...] attended care after a slightly longer duration of symptoms (median of 2.9...
Clonal expansion of artemisinin-resistant <em>Plasmodium falciparum</em> in Uganda is associated with substandard treatment practices (Publications)
the frame of the Community Access to Rectal Artesunate for Malaria project, blood samples were collected from children with signs of severe malaria before and after RAS implementation. K13 polymorphisms were [...] a driver of this recent emergence. Rectal artesunate (RAS) as pre-referral treatment for severe malaria in children was implemented in 2019 in Northern Uganda. The objective of this study was to determine
Feasibility of repellent use in a context of increasing outdoor transmission: a qualitative study in rural Tanzania (Publications)
long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) has substantially reduced malaria morbidity and mortality in sub-Saharan Africa. These tools target indoor resting and biting vectors [...] may select for vectors that bite and rest outdoors. Thus, to significantly impact this residual malaria transmission outdoors, tools targeting outdoor transmission are required. Repellents, used for personal [...] hinges upon its community acceptability. This study assessed the...
