Limited polymorphism in <em>Plasmodium falciparum</em> sexual-stage antigens (Publications)
In areas highly endemic for malaria, individuals are frequently found to be infected simultaneously with multiple Plasmodium falciparum clones. This raises the question of whether all parasite clones produce

result, peak prevalence was reached in 3-5 years old children. However, the prevalence of clinical malaria (estimated from the excess risk of axillary temperatures > or = 37.5 degrees C attributable to p
Anti-malarial ozonides OZ439 and OZ609 tested at clinically relevant compound exposure parameters in a novel ring-stage survival assay (Publications)
BACKGROUND: Drug efficacy against kelch 13 mutant malaria parasites can be determined in vitro with the ring-stage survival assay (RSA). The conventional assay protocol reflects the exposure profile of

vaccine formulations, circulating Tfh cells were expanded in Tanzanian volunteers when an experimental malaria vaccine was adjuvanted in GLA-SE but not when formulated in Alum. The GLA-SE-formulated peptide was
Inhibition of <em>Plasmodium falciparum</em> Hsp90 contributes to the antimalarial activities of aminoalcohol-carbazoles (Publications)
Malaria caused by the protozoan parasite Plasmodium falciparum (Pf) remains a major public health problem throughout the developing world. One molecular target that should receive more attention is the

distribution of insecticide-treated nets. Here, we provide an update on phenotypic IR in four highly malaria-endemic areas of PNG. IR against deltamethrin, lambda-cyhalothrin, and dichlorodiphenyltrichloroethane
Relationship between insecticide resistance profiles in <em>Anopheles gambiae</em> <em>sensu lato</em> and agricultural practices in Côte... (Publications)
BACKGROUND: Insecticide-based malaria vector control is increasingly undermined due to the development of insecticide resistance in mosquitoes. Insecticide resistance may partially be related to the use [...] s between the type of agricultural practices and certain insecticide resistance profiles in the malaria vector An. gambiae s.l. which might arise from the use of pesticides deployed for protecting crops

Furthermore, survival of malaria transmitting Anopheles mosquitoes is strongly decreased after feeding on humans recently treated [...] . Currently, mass drug administration of ivermectin is under investigation as a potential novel malaria vector control tool to reduce Plasmodium transmission by mosquitoes. A "post-ivermectin effect" has
Expression of the MSPDBL2 antigen in a discrete subset of <em>Plasmodium falciparum</em> schizonts is regulated by GDV1 but may not be linked to... (Publications)

IMPORTANCE: Malaria parasites in the blood are remarkably variable, able to switch antigenic targets so they may survive [...] developed specific immune responses. This is one of the challenges in developing vaccines against malaria. MSPDBL2 is a target of naturally acquired immunity expressed in minority proportions of schizonts
