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 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...
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...
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...
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...

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
The influence of zinc supplementation on morbidity due to <em>Plasmodium falciparum</em>: a randomized trial in preschool children in Papua New Guinea (Publications)
determine the influence of zinc on malaria morbidity we conducted a randomized placebo-controlled trial of daily zinc supplementation in children residing in a malaria endemic region of Papua New Guinea [...] mg elemental zinc (n = 136) or placebo (n = 138) for 6 days a week for 46 weeks. Slide-confirmed malaria episodes were detected by surveillance of cases self-reporting to a local health center. Cross-sectional
Estimating the duration of Plasmodium falciparum infection from trials of indoor residual spraying (Publications)
cross-sectional survey data collected from three historical trials of indoor residual spraying against malaria: one from two contiguous districts in Tanzania-Kenya (Pare Taveta) carried out in 1954, the others [...] showed considerable variation but no general age trend. There was also no clear relationship between malaria endemicity and infection duration. Analyses of successive sampling from the same individuals with [...] areas. Periods of several years may be required to evaluate long-term...
