Effect of RTS,S/AS01E vaccine booster dose on cellular immune responses in African infants and children (Publications)
RTS,S/AS01(E), the first approved malaria vaccine, demonstrated moderate efficacy during the phase 3 pediatric trial. We previously investigated cell-mediated immune (CMI) responses following the primary [...] from 709 children and infants after RTS,S/AS01(E) antigen stimulation, and their associations with malaria risk and antibodies one month post-booster and one year later were assessed. IL-2, IFN-γ, IL-17, [...] circumsporozoite protein (CSP) remained higher after one year. IL-2 was...
Antimalarial agents derived from metal-amodiaquine complexes with activity in multiple stages of the <em>Plasmodium</em> life cycle (Publications)
Malaria is the one of the deadliest infectious diseases worldwide. Chemically, quinolines are excellent ligands for metal coordination and are deployed as drugs for malaria treatment. There is a growing [...] coordination with antimalarial quinolines is a potential chemical tool for drug design and discovery in malaria and other infectious diseases susceptible to quinoline treatment.
The impact of using primaquine without prior G6PD testing: a case series describing the obstacles to the medical management of haemolysis (Publications)
vivax malaria in glucose-6-phosphate dehydrogenase (G6PD) deficient individuals employs weekly primaquine dosing. This is the only recommended regimen for this patient sub-group. If national malaria programs [...] with unknown G6PD status from two different countries were prescribed primaquine as per national malaria program guidelines. During treatment both patients presented to the clinic with symptoms of anaemia
Pan-Africa Network for Genomic Surveillance of Poverty Related Diseases and Emerging Pathogens (Projects)
https://www.swisstph.ch/en/projects/project-detail/project/pan-africa-network-for-genomic-surveillance-of-poverty-related-diseases-and-emerging-pathogens
The main objective of the PANGenS project is to use genomic epidemiology of tuberculosis, malaria and emerging and re-emerging pathogens in Africa to better understand disease etiology, dynamics of disease [...] will aid infectious disease monitoring, and genomic surveillance will detect drug-resistant TB and malaria parasites. To achieve this, PANGenS will develop genomic epidemiology capacity across Africa by [...] components, from wet lab to bioinformatics, and to establish proof-of-concept...
Identification of a potential antimalarial drug candidate from a series of 2-aminopyrazines by optimization of aqueous solubility and potency across... (Publications)
blood life-cycle stage of the human malaria parasite Plasmodium falciparum. Several compounds displayed high in vivo efficacy in two different mouse models for malaria, P. berghei-infected mice and P. f
Cryptic population structure and insecticide resistance in <em>Anopheles gambiae</em> from the southern Democratic Republic of Congo (Publications)
Congo (DRC) suffers from one of the highest malaria burdens worldwide, but information on its Anopheles vector populations is relatively limited. Preventative malaria control in DRC is reliant on pyrethroid-treated

Modelling the impact of insecticide-based control interventions on the evolution of insecticide resistance and disease transmission (Publications)
threshold level of mosquitoes below which transmission of malaria is interrupted. It is based on a classic Ross-Macdonald derivation of the malaria basic reproductive number (R0) and may be used to assess [...] (iv) the impact of resistance once it has arisen and, in particular, whether it is sufficient for malaria transmission to resume. The model consists of a system of difference equations that tracks the immature [...] and easily generalizable to many scenarios using different calibrations...
Emergence of FY*A(null) in a <em>Plasmodium vivax</em>-endemic region of Papua New Guinea (Publications)
Human genetic polymorphisms of this nature are common in malarious regions, and all four human malaria parasites are holoendemic below 1500 meters in PNG. At this elevation, a prominent condition cha [...] demonstrated that alpha(+)-thalassemia is associated with increased susceptibility to uncomplicated malaria among young children. It is further proposed that alpha(+)-thalassemia may facilitate so- called [...] vivax infection to act later in life as a "natural vaccine" against severe...
Ethnobotanical study of some of mosquito repellent plants in north-eastern Tanzania (Publications)
potential for malaria vector control requires evaluation in areas with different level of malaria endemicity. The essential oils of Ocimum suave and Ocimum kilimandscharicum were evaluated against malaria vectors [...] filter papers impregnated with Ocimum extracts, knockdown effects and mortality was investigated on malaria mosquito Anopheles arabiensis and Anopheles gambiae, including a nuisance mosquito, Culex quinqu
