Comparison of analytical methods for the evaluation of antibody responses against epitopes of polymorphic protein antigens (Publications)
Surface exposed protein antigens of the malaria parasite Plasmodium falciparum frequently harbor multiple dimorphic amino acid positions. These are associated with parasite immune evasion and represent [...] the humoral immune response against a semiconserved sequence (YX(44)LFX(47)KEKMX(52)L) of the key malaria blood stage vaccine candidate merozoite surface protein-1 (MSP-1). Monoclonal antibodies (mAbs) raised [...] MSP-1(43-53) variant sequences. When used for the evaluation of humoral...
Next generation chemiluminescent probes for antimalarial drug discovery (Publications)
Malaria is caused by parasites of the Plasmodium genus and remains one of the most pressing human health problems. The spread of parasites resistant to or partially resistant to single or multiple drugs [...] frontline antimalarial artemisinin and its derivatives, poses a serious threat to current and future malaria control efforts. In vitro drug assays are important for identifying new antimalarial compounds and [...] detection limit of less than 100 parasites of the presented biosensor system...
Pan-Africa Network for Genomic Surveillance of Poverty Related Diseases and Emerging Pathogens (Projects)
https://www.swisstph.ch/fr/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...
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
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...

Malaria blood slide results from health centre [...] 2006-March 2007), 7056 attendances were recorded in 9880 infants aged 2-11 months, 50% with clinical malaria. Monthly supervision visits highlighted incomplete recording of information between OPD and laboratory
Strong off-target antibody reactivity to malarial antigens induced by RTS,S/AS01E vaccination is associated with protection (Publications)
lower clinical malaria incidence after adjusting for age group, site and post-vaccination anti-CSP levels. RTS,S/AS01E-induced IgG may bind strongly not only to CSP, but to unrelated malaria antigens, and [...] and this seems to either confer, or at least be a marker of, increased protection from clinical malaria.
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.
