Nevertheless, an epidemiological study in 2012 demonstrated higher malaria prevalence among bed net users than non-users [...] against malaria. Houses with well-screened windows, with doors that shut properly, and that use insecticidal sprays against mosquitoes, were said not to use bed nets, while frequent attacks from malaria was [...] compromise its effectiveness and supposedly increase of malaria...
Multiple insecticide resistance in <em>Anopheles gambiae</em> from Tanzania: a major concern for malaria vector control (Publications)
development of insecticide resistance in the major malaria vectors. This study was carried out to monitor the susceptibility status of major malaria vectors to insecticides used for IRS and LLINs in mainland [...] BACKGROUND: Malaria vector control in Tanzania is based on use of long-lasting insecticide treated nets (LLINs) and indoor residual spraying (IRS), which both rely on the use of chemical insecticides. [...] An. gambiae sensu stricto (s.s.) Kisumu strain. RESULTS: Anopheles arabiensis...
Lysophosphatidylcholine regulates sexual stage differentiation in the human malaria parasite <em>Plasmodium falciparum</em> (Publications)
bottleneck in the Plasmodium life cycle and a key intervention target of ongoing efforts to eradicate malaria. Sexual differentiation is essential for this process, as only sexual parasites, called gametocytes [...] activation of sexual-stage-specific transcription and gametocyte formation. Our results reveal that malaria parasites can sense and process host-derived physiological signals to regulate differentiation. These [...] of the sexual differentiation pathway in Plasmodium that may provide...
Changes in malaria burden and transmission in sentinel sites after the roll-out of long-lasting insecticidal nets in Papua New Guinea (Publications)
exhibits a complex malaria epidemiology due to diversity in malaria parasites, mosquito vectors, human hosts, and their natural environment. Heterogeneities in transmission and burden of malaria at various scales [...] scales are likely to affect the success of malaria control interventions, and vice-versa. This manuscript assesses changes in malaria prevalence, incidence and transmission in sentinel sites following the [...] Diagnosis of malaria infection in humans was done by rapid diagnostic...
Spatially variable risk factors for malaria in a geographically heterogeneous landscape, western Kenya: an explorative study (Publications)
factors for malaria can give insight into which human and environmental characteristics play important roles in sustaining malaria transmission. METHODS: On Rusinga Island, western Kenya, malaria infection [...] negatively associated with malaria prevalence. DISCUSSION: Identification of risk factors for malaria that vary geographically can provide insight into the local epidemiology of malaria. Examining spatially [...] Combining the data from both surveys, overall malaria prevalence was 24 %....
A malaria risk map of Kinshasa, Democratic Republic of Congo (Publications)
This study presents the first malaria risk map of Kinshasa, a mega city of roughly 10 million inhabitants and located in a highly endemic malaria zone. Prevalence of malaria, anaemia and reported fever was [...] prevalence for malaria and anaemia was 6.4 % (5.6-7.4) and 65.1 % (63.7-66.6) in 2009, and 17.0 % (15.7-18.3) and 64.2 % (62.6-65.9) in 2011. In two HZs sampled in both surveys, malaria prevalence was [...] BACKGROUND: In Kinshasa, malaria remains a major public health problem but its...
Stakeholders' opinions and questions regarding the anticipated malaria vaccine in Tanzania (Publications)

Ecological drivers of <em>Mansonella perstans</em> infection in Uganda and patterns of co-endemicity with lymphatic filariasis and malaria (Publications)
BACKGROUND: Mansonella perstans is a widespread, but relatively unknown human filarial parasite transmitted by Culicoides biting midges. Although it is found in many parts of sub-Saharan Africa, only
Low prevalence of <em>Plasmodium</em> and absence of malaria transmission in Conakry, Guinea: prospects for elimination (Publications)

This study addresses the bio-ecology of larval and adult stages of malaria vectors [...] using the VecTest malaria panel assay and an enzyme-linked immunosorbent assay. A systematic research of Ministry of Health statistical yearbooks was performed to determine malaria prevalence in children [...] infection in Anopheles gambiae s.l. in the city of Conakry, Guinea, and...
