Peripheral blood dendritic cells in children with acute <em>Plasmodium falciparum</em> malaria (Publications)
children suffering from acute malaria in Kilifi, Kenya. Comparable percentages of CD83(+) DCs were found in peripheral blood of healthy children and children with malaria. However, the percentage of HLA-DR(+) [...] qualitative and quantitative analysis of these cells in various human diseases. Plasmodium falciparum malaria is characterized by the poor induction of long-lasting protective immune responses. This study, therefore [...] HLA-DR(+) peripheral blood DCs was significantly reduced in...
Severe malaria and concomitant bacteraemia in children admitted to a rural Mozambican hospital (Publications)
severe malaria. RESULTS: Seven thousand and forty-three children were admitted with a diagnosis of malaria. 25.2% fulfilled the criteria for severe malaria. 5.4% of the children with severe malaria and valid [...] rates of severe malaria cases rose steeply when bacteraemia was also present (from 4.0% to 22.0%, P < 0.0001), and bacteraemia was an independent risk factor for death among severe malaria patients (adjusted [...] associated with severe malaria syndromes, or anaemia severity groups. No...
The effects of untreated bednets on malaria infection and morbidity on the Kenyan coast (Publications)
protected against both malaria infection and clinical disease compared with children not sleeping under bednets. The study was conducted in Kilifi District, Kenya, during the malaria season (June-August, [...] P = 0.47). When these same children were followed-up during the malaria season, there was evidence of a lower rate of clinical malaria among those that used untreated nets in good condition (adjusted [...] or = 10 years. Data collected from a cross-sectional survey showed evidence of...
Effective autodissemination of pyriproxyfen to breeding sites by the exophilic malaria vector <em>Anopheles arabiensis</em> in semi-field settings in... (Publications)
autodissemination of PPF to breeding habitats by malaria vectors. These findings highlight the potential for this technique for outdoor control of malaria vectors and call for the testing of this technique [...] BACKGROUND: Malaria vector control strategies that target adult female mosquitoes are challenged by the emergence of insecticide resistance and behavioural resilience. Conventional larviciding is restricted
The epidemiology of malaria and anaemia in the Bonikro mining area, central Côte d'Ivoire (Publications)
BACKGROUND: The epidemiology of malaria and anaemia is characterized by small-scale spatial and temporal heterogeneity, which might be influenced by human activities, such as mining and related disturbance [...] sector involvement holds promise to foster public health, including the prevention and control of malaria and anaemia. Here, results from a cross-sectional epidemiological survey, conducted in communities [...] haemoglobin (Hb) was measured to determine anaemia. Additionally, mothers...
Modelling heterogeneity in malaria transmission using large sparse spatio-temporal entomological data (Publications)
Background: Malaria transmission is measured using entomological inoculation rate (EIR), number of infective mosquito bites/person/unit time. Understanding heterogeneity of malaria transmission has been [...] database compiled by the Malaria Transmission Intensity and Mortality Burden across Africa (MTIMBA) project (2001-2004) at several sites is the most suitable dataset for studying malaria transmission-mortality [...] a rigorous approach for analysing large and highly variable entomological...
An experimental hut study to quantify the effect of DDT and airborne pyrethroids on entomological parameters of malaria transmission (Publications)
BACKGROUND: Current malaria vector control programmes rely on insecticides with rapid contact toxicity. However, spatial repellents can also be applied to reduce man-vector contact, which might ultimately [...] ultimately impact malaria transmission. The aim of this study was to quantify effects of airborne pyrethroids from coils and DDT used an indoor residual spray (IRS) on entomological parameters that influence [...] influence malaria transmission. METHODS: The effect of Transfluthrin and...
