Safety and protective efficacy of PfSPZ vaccine administered to HIV negative and positive Tanzanian adults (Publications)
PfSPZ Vaccine, composed of attenuated Plasmodium falciparum (Pf) sporozoites (SPZ), protects against malaria. We conducted this clinical trial to assess the safety and efficacy of PfSPZ Vaccine in HIV positive [...] ts received 5 doses of PfSPZ Vaccine or normal saline over 28 days followed by controlled human malaria infection (CHMI) 3 weeks later. RESULTS: There were no solicited adverse events in the 9 HIV- and
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
Semi-field experiments reveal contrasted predation and movement patterns of aquatic macroinvertebrate predators of Anopheles gambiae larvae (Publications)
BACKGROUND: Members of the Anopheles gambiae complex are major malaria vectors in sub-Saharan Africa. Their larval stages inhabit a variety of aquatic habitats in which, under natural circumstances, they [...] taxa of aquatic macroinvertebrate predators. Understanding the potential impact of predators on malaria vector larval population dynamics is important for enabling integrated local mosquito control programmes
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
An evidence synthesis approach for combining different data sources illustrated using entomological efficacy of insecticides for indoor residual... (Publications)
BACKGROUND: Prospective malaria public health interventions are initially tested for entomological impact using standardised experimental hut trials. In some cases, data are collated as aggregated counts [...] residual spray (IRS) product active ingredient, used on wall surfaces to kill mosquitoes and reduce malaria transmission, were analysed using a series of statistical models to understand the benefits and
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
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

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

In an agricultural area of Southern Cote d'Ivoire, the main malaria vector Anopheles coluzzii shows multiple resistance across insecticides mediated by both target site [...] mutation in Cote d'Ivoire, and as in other populations, it is found in both dominant West African malaria vector species. Continued monitoring of N1575Y is underway, as are studies to elucidate its contribution
