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
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...
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...
The bacterial redox signaller pyocyanin as an antiplasmodial agent: comparisons with its thioanalog methylene blue (Publications)
cavity of the enzyme. Like MB, also PYO was also found to be active against blood schizonts of the malaria parasite P. falciparum in vitro. Furthermore, both compounds were active against the disease transmitting [...] PYO, is well tolerated and represents a promising agent for MB-based combination therapies against malaria. Current and future clinical studies can be guided by the comparisons between MB and PYO reported [...] reported here. Additionally, it is of interest to study if and to what...
Identification of new PNEPs indicates a substantial non-PEXEL exportome and underpins common features in<em> Plasmodium falciparum</em> protein export (Publications)
Malaria blood stage parasites export a large number of proteins into their host erythrocyte to change it from a container of predominantly hemoglobin optimized for the transport of oxygen into a niche [...] how many further PNEPs exist. Here we report the identification of new PNEPs in the most virulent malaria parasite Plasmodium falciparum. This includes proteins with a domain structure deviating from previously [...] highlighting protein translocation in the parasite periphery as a general...
Spatial effects of mosquito bednets on child mortality (Publications)
Insecticide treated nets (ITN) have been proven to be an effective tool in reducing the burden of malaria. Few randomized clinical trials examined the spatial effect of ITNs on child mortality at a high [...] coverage. We analyzed for the first time data from a large follow-up study in an area of high perennial malaria transmission in southern Tanzania to describe the spatial effects of bednets on all-cause child mortality [...] with insecticide, and (2) the relative homogeneity of coverage with...
Spatial risk profiling of <em>Plasmodium falciparum</em> parasitaemia in a high endemicity area in Côte d'Ivoire (Publications)
in a high endemicity area of Africa, and to specify how this information can facilitate improved malaria control at the district level. METHODS: A questionnaire was administered to about 4,000 schoolchildren [...] parasitaemia. After accounting for spatial correlation, age, bed net coverage, rainfall during the main malaria transmission season and distance to rivers remained significant covariates. CONCLUSION: It is argued [...] villages in close proximity to rivers, in concert with other...
Case studies in public-private-partnership in health with the focus of enhancing the accessibility of health interventions (Publications)
level NGO consortium with a focus on malaria and the second one is an international advocacy group with an overarching goal of protecting children against malaria through an innovative mechanism. The case [...] case study approach is used to analyze why the PPP approach was used to address malaria control and how it was implemented. Both PPPs demonstrated that relationships between the public and private sector
