Very high carriage of gametocytes in asymptomatic low-density <em>Plasmodium falciparum</em> and <em>P. vivax</em> infections in western Thailand (Publications)
Plasmodium spp. are common in low endemicity areas worldwide, but outside Africa, their contribution to malaria transmission is poorly understood. Community-based studies with highly sensitive molecular diagnostics [...] gametocytes indicates that these infections may contribute substantially to the maintenance of local malaria transmission.

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
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

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

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
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
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

Through the TaqMan-Array [...] the most prevalent pathogen (10.2%). Overall, 69% (357/516) of patients with clinical diagnoses of malaria, respiratory, or gastrointestinal infections were prescribed a WHO-guideline-recommended empiric
