Performance of antigen concentration thresholds for attributing fever to malaria among outpatients in Angola (Publications)
The density of malaria parasites is a key determinant in whether or not an infected individual develops fever. While the pyrogenic threshold for malaria parasite density has been well-studied, there is [...] latent-class modeling to attribute malaria etiology to the fevers and to estimate the sensitivity and specificity of different antigen thresholds for detecting malaria fevers. Amongst patients positive [...] febrile HRP2+ patients compared to afebrile HRP2+ patients. When considering HRP2...
Rapid multiplex gene expression assays for monitoring metabolic resistance in the major malaria vector <em>Anopheles gambiae</em> (Publications)
BACKGROUND: Metabolic resistance of the major malaria vector Anopheles gambiae (s.l.) to insecticides is operationally significant, particularly in combination with target site resistance. However, detection
Early antischistosomal leads identified from<em> in vitro</em> and<em> in vivo</em> screening of the Medicines for Malaria Venture pathogen box (Publications)
Facing an almost dry drug development pipeline, screening the Pathogen Box from the Medicines for Malaria Venture (MMV), provides a unique opportunity to possibly expand the pool of potent molecules against

CONCLUSIONS: This study confirms that in malaria endemic settings, sub-patent malaria infections among blood donors [...] ansmitted malaria are nucleic acid-based molecular approaches such as quantitative polymerase chain reaction. The study was undertaken to determine the prevalence of sub-microscopic malaria parasite infection [...] collected from healthy donors living in Malabo, P. falciparum, P. malar...
Dramatic decreases of malaria transmission intensities in Ifakara, south-eastern Tanzania since early 2000s (Publications)
000) historically experienced moderate to high malaria transmission, mediated mostly by Anopheles gambiae and Anopheles funestus. In early 2000s, malaria transmission [Plasmodium falciparum entomological [...] outdoors in Katindiuka-ward by HLC), resulting in overall PfEIR of 0.102 ib/p/yr. Nearly 80% of malaria vectors were from Katindiuka and Mlabani wards. Anopheles gambiae densities were higher outdoors [...] Most houses had brick walls and/or iron roofs (> 90%), and 52% had screened...
Baseline exposure, antibody subclass, and hepatitis B response differentially affect malaria protective immunity following RTS,S/AS01E vaccination in... (Publications)
IgG4, subclass responses. Age, site, previous malaria episodes, and baseline characteristics including antibodies to CSP and other antigens reflecting malaria exposure and maternal IgGs, nutritional status [...] anti-HBsAg antibodies induced by RTS,S/AS01E vaccination were associated with malaria protection. In contrast, higher malaria exposure at baseline and non-cytophilic IgG responses to CSP were associated [...] BACKGROUND: The RTS,S/AS01E vaccine provides partial protection against malaria...
Outdoor malaria transmission risks and social life: a qualitative study in South-Eastern Tanzania (Publications)
BACKGROUND: Behaviour changes in mosquitoes from indoor to outdoor biting result in continuing risk of malaria from outdoor activities, including routine household activities and occasional social and cultural [...] of various social and cultural gatherings that incidentally expose people to mosquito bites and malaria infection. RESULTS: Religious, cultural and social gatherings involving the wider community are conducted [...] work towards elimination. Focusing on single interventions will not...
Identifying key factors of the transmission dynamics of drug-resistant malaria (Publications)
Development of resistance to malaria treatments remains a great threat to continued malaria burden reduction and elimination. Quantifying the impact of key factors which increase the emergence and spread
