Resistance of <em>Anopheles stephensi</em> to selected insecticides used for indoor residual spraying and long-lasting insecticidal nets in Ethiopia (Publications)
BACKGROUND: Malaria, transmitted by the bite of infective female Anopheles mosquitoes, remains a global public health problem. The presence of invasive Anopheles stephensi, capable of transmitting Plasmodium [...] 2016. The ecology of this mosquito species differs from that of Anopheles arabiensis, the primary malaria vector in Ethiopia. This study aimed to evaluate the efficacy of selected insecticides, which are [...] are used in indoor residual spraying (IRS) and selected long-lasting...
Determinants of bed net use conditional on access in population surveys in Ghana (Publications)
e-treated nets (ITNs) are one of the most effective and widely available methods for preventing malaria, and there is interest in understanding the complexities of behavioural drivers of non-use among [...] access to a net. METHODS: Survey data from the Ghana 2014 Demographic and Health Survey and the 2016 Malaria Indicator Survey were used to calculate household members' access to space under a net as well as [...] households when compared to the poorest category. In 2014, exposure to messages...
Co-infection of the four major <em>Plasmodium </em>species: effects on densities and gametocyte carriage (Publications)
BACKGROUND: Co-infection of the four major species of human malaria parasite Plasmodium falciparum (Pf), P. vivax (Pv), P. malariae (Pm), and P. ovale sp. (Po) is regularly observed, but there is limited [...] (95% CI: 0.95, 1.79) for gametocytes. This excess co-infection risk was partially attributable to malaria infections clustering in some villages. Pf-Pv-Pm triple infections were four times more frequent
Long-term acceptability, durability and bio-efficacy of ZeroVector® durable lining for vector control in Papua New Guinea (Publications)
had previously been installed in 40 homes across four study sites representing a cross section of malaria transmission risk and housing style. Structured questionnaires, DL visual inspections and group [...] at 36-months post-installation, the material and fixtures proved durable and the efficacy against malaria vectors did not decrease. However, the DL material had been removed from over 50% of the original [...] suggest DL may not be an appropriate vector control method for large-scale use in...
Molecular methods for tracking residual <em>Plasmodium falciparum </em>transmission in a close-to-elimination setting in Zanzibar (Publications)
essential for surveillance studies conducted to inform malaria control strategies in close-to-elimination settings. Molecular monitoring of residual malaria infections usually requires a large study size, therefore [...] screening large sample sets represents primarily a research tool that should inform the design of malaria elimination strategies. It may also prove beneficial for diagnostic tasks in surveillance-response
Do bednets including piperonyl butoxide offer additional protection against populations of<em> Anopheles gambiae s.l. </em>that are highly resistant... (Publications)
Malaria control is dependent on the use of longlasting insecticidal nets (LLINs) containing pyrethroids. A new generation of LLINs containing both pyrethroids and the synergist piperonyl butoxide (PBO) [...] (PBO) has been developed in response to increasing pyrethroid resistance in African malaria vectors, but questions remain about the performance of these nets in areas where levels of pyrethroid resistance
Activity refinement of aryl amino acetamides that target the <em>P. falciparum</em> STAR-related lipid transfer 1 protein (Publications)
Malaria is a devastating disease that causes significant morbidity worldwide. The development of new antimalarial chemotypes is urgently needed because of the emergence of resistance to frontline therapies [...] a useful tool for further investigating the druggability of PfSTART1 across the lifecycle of the malaria parasite.
Polyamidoamine nanoparticles for the oral administration of antimalarial drugs (Publications)

Liquid chromatography with tandem mass spectrometry analysis of affinity chromatography-purified [...] coinfections such as Plasmodium and Leishmania. When fluorescein-labeled PAAs were fed to females of the malaria mosquito vectors Anopheles atroparvus and Anopheles gambiae, persistent fluorescence was observed
Synthesis and structure-activity relationships of new 2-phenoxybenzamides with antiplasmodial activity (Publications)
The 2-phenoxybenzamide 1 from theMedicines for Malaria Venture Malaria Box Project has shown promising multi-stage activity against different strains of P. falciparum. It was successfully synthesized via
From magic bullet to magic bomb: reductive bioactivation of antiparasitic agents (Publications)
human cells. Examples are the enzymes of folate synthesis or of the nonmevalonate pathway in the malaria parasites. However, there are other ways how a drug can kill selectively. Of particular relevance [...] the host, as this is how the current frontrunners of parasite chemotherapy work. Artemisinins for malaria, fexinidazole for human African trypanosomiasis, benznidazole for Chagas' disease, metronidazole
