Mass mosquito trapping for malaria control in western Kenya: study protocol for a stepped wedge cluster-randomised trial (Publications)
of malaria threaten the efficacy of existing vector control tools used against malaria mosquitoes. The development of odour-baited mosquito traps has led to the possibility of controlling malaria through [...] mass mosquito trapping could be an effective tool for elimination of malaria. If proven to be effective, this novel approach to malaria control would be a valuable addition to the existing strategies of [...] through mass trapping of malaria vectors. Through daily removal trapping against...
Hemolysis after oral artemisinin combination therapy for uncomplicated <em>Plasmodium falciparum</em> malaria (Publications)
weeks after treatment of severe malaria with intravenous artesunate have been described. We performed a prospective observational study of patients with uncomplicated malaria to investigate whether posttreatment [...] occurs after oral artemisinin-based combination therapy. Eight of 20 patients with uncomplicated malaria who were given oral artemisinin-based combination therapy met the definition of posttreatment hemolysis [...] g/dL; p = 0.002). These findings indicate a need for increased...
Pregnant women and infants as sentinel populations to monitor prevalence of malaria: results of pilot study in Lake Zone of Tanzania (Publications)
screened for malaria infection using a malaria rapid diagnostic test (RDT) from December 2012 to November 2013, regardless of symptoms. Participants who tested positive were treated for malaria per national [...] BACKGROUND: As malaria control interventions are scaled-up, rational approaches are needed for monitoring impact over time. One proposed approach includes monitoring the prevalence of malaria infection among [...] facility (HF) visits. This pilot explored the feasibility and utility of...
Structure of the malaria vaccine candidate antigen CyRPA and its complex with a parasite invasion inhibitory antibody (Publications)
Invasion of erythrocytes by Plasmodial merozoites is a composite process involving the interplay of several proteins. Among them, the Plasmodium falciparum Cysteine-Rich Protective Antigen (PfCyRPA) i
Malaria vectors and their blood-meal sources in an area of high bed net ownership in the western Kenya highlands (Publications)
BACKGROUND: Blood-meal sources of malaria vectors affect their capacity to transmit the disease. Most efficient malaria vectors prefer human hosts. However, with increasing personal protection measures [...] measures it becomes more difficult for them to find human hosts. Here recent malaria vector blood-meal sources in western Kenya highlands were investigated. METHODS: Adult mosquitoes resting indoors, outdoors [...] domesticated animals and 83.6 % had people sharing houses with livestock at...
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...
Investigating sulfoxide-to-sulfone conversion as a prodrug strategy for a phosphatidylinositol 4-kinas inhibitor in a humanized mouse model of malaria (Publications)
its corresponding sulfone metabolite, were evaluated in the NOD-scid IL2Rgamma(null) (NSG) murine malaria disease model of Plasmodium falciparum infection. We hypothesized that the sulfoxide would serve [...] dosed, thereby demonstrating that the sulfoxide served as an effective prodrug for the treatment of malaria.
Community-based prevalence of typhoid fever, typhus, brucellosis and malaria among symptomatic individuals in Afar Region, Ethiopia (Publications)
650 suspected individuals for malaria, 16 (2.5%) were found positive for P. falciparum infection. CONCLUSION: In this study, typhoid fever, typhus, brucellosis and malaria were observed among symptomatic [...] scarcity of proper diagnostic tools, febrile illness related symptoms are often misdiagnosed as malaria. Information on causative agents of febrile illness related symptoms among pastoral communities in [...] based cross-sectional survey, we assessed the prevalence of typhoid fever,...
