Multiplicity of <em>Plasmodium falciparum</em> infection following intermittent preventive treatment in infants (Publications)
Intermittent preventive treatment in infants with sulphadoxine-pyrimethamine (IPTi-SP) reduces malaria morbidity by 20% to 33%. Potentially, however, this intervention may compromise the acquisition of [...] of polyclonal infections (69.6% vs. 69.7%; P = 0.99). Adjusting for study site, current and prior malaria, parasite density, and season did not change this finding. CONCLUSIONS: IPTi-SP appears to have no
A 10 year study of the cause of death in children under 15 years in Manhica, Mozambique (Publications)
diseases accounted for 9.5% of the defined causes of death, and injuries for 3.9% of causes of deaths. Malaria was the single largest cause, accounting for 21.8% of cases. Pneumonia with 9.8% was the second leading [...] area. The pattern of childhood mortality in Manhica area is typical of developing countries where malaria, pneumonia and HIV/AIDS are important causes of death
<em>Plasmodium vivax</em> and <em>Plasmodium falciparum</em> infection dynamics: re-infections, recrudescences and relapses (Publications)
BACKGROUND: In malaria endemic populations, complex patterns of Plasmodium vivax and Plasmodium falciparum blood-stage infection dynamics may be observed. Genotyping samples from longitudinal cohort studies [...] CONCLUSION: The statistical model developed here provides a useful new tool for in-depth analysis of malaria data from longitudinal cohort studies, and future application to data sets with multi-locus genotyping
Gestational SARS-CoV-2 infection in a Ugandan birth cohort: high incidence, mild maternal disease, and evidence of association with transient infant... (Publications)
Many questions remain about the prevalence and effects of SARS-CoV-2 infection in malaria-endemic African countries like Uganda, particularly in vulnerable groups such as pregnant women. We describe SARS-CoV-2 [...] immunoglobulin (Ig)G and IgM antibody responses and clinical outcomes in mother-infant dyads enrolled in malaria chemoprevention trials in Uganda. From December 2020-February 2022, among 400 unvaccinated pregnant
Activation of TCR Vδ1+ and Vδ1-Vδ2- γδ T cells upon controlled infection with <em>Plasmodium falciparum</em> in Tanzanian volunteers (Publications)
immune response to malaria remains incomplete. Clinical trials using whole-sporozoite-based vaccination approaches such as the Sanaria PfSPZ Vaccine, followed by controlled human malaria infection (CHMI)
New myxobacteria of the <em>Myxococcaceae</em> clade produce angiolams with antiparasitic activities (Publications)
named angiolams B, C, and D were found to display promising antiparasitic activities against the malaria pathogen Plasmodium falciparum in the 0.3-0.8 µM range.IMPORTANCEThe COVID-19 pandemic and continuously [...] diseases. However, the shortage of treatment options against protozoal parasitic infections, like malaria, is much more severe, especially for the treatment of so-called neglected tropical diseases. The
The Shockwè trap: a human-baited exposure-free device for surveillance and behaviour studies of anthropophilic vectors (Publications)
entomological inoculation rate (EIR) are common parameters routinely used to measure the risk of malaria transmission. Both parameters can be estimated using human landing catches (HLC). Although it is [...] human-exposure free device for monitoring the occurrence of a wide range of mosquito, including major malaria and arboviruses vector species. However, improvements are needed to increase its sampling efficiency
Elimination of <em>Schistosoma mansoni</em> in infected mice by slow release of artemisone (Publications)

We infected adult mice by subcutaneous injection of S. mansoni cercariae (about 200) and treated [...] release of the artemisone that was verified in vivo and in vitro bioassays using drug-sensitive malaria parasites. We found superior strong anti-schistosome effects up to a total reduction of worm number
DDT contamination in water resources of some African countries and its impact on water quality and human health (Publications)
use in indoor residual spraying (IRS) in developing countries, including African countries, for malaria control. There have been no previous reviews on DDT residues in water resources in Africa. The study [...] risk in sampled drinking sources within African water systems. Therefore, alternative methods for malaria vector control should be investigated and applied.
Temporal distribution of <em>Plasmodium falciparum </em>recrudescence following artemisinin-based combination therapy: an individual participant data... (Publications)

METHODS: Individual patient data from 83 anti-malarial efficacy studies collated in the WorldWide [...] constructed distribution was used to estimate the optimal follow-up period for capturing a P. falciparum malaria recrudescence. Simulation studies were conducted based on the constructed distributions to quantify
