intermediate host snails of parasitic diseases related to water, and to assess the prevalence of malaria, schistosomiasis and soil-transmitted helminthiasis before dam construction. Mosquitoes were caught [...] in water bodies, and microscopic analyses of blood, stool and urine samples were carried out. Two malaria vector species were identified: Anopheles gambiae and Anopheles funestus. The average infective rate [...] asis and soil-transmitted helminthiasis was low. Our studies revealed...
Indifferent to disease: a qualitative investigation of the reasons why some Papua New Guineans who own mosquito nets choose not to use them (Publications)
regarding malaria transmission pathways or the utility of mosquito nets did not appear to underlie this indifference. Rather, the indifference appeared to be rooted in a lack of fear of malaria infection [...] render individual mosquito net use as easy and as convenient as possible and to promote complementary malaria control strategies where appropriate
Preclinical evaluation of the antifolate QN254, 5-chloro- N'6'-(2,5-dimethoxy-benzyl)-quinazoline-2,4,6-triamine, as an antimalarial drug... (Publications)
inhibitors-such as pyrimethamine (PM)-has now spread to almost all regions where malaria is endemic, rendering antifolate-based malaria treatments highly ineffective. We have previously shown that the di-amino [...] highly PM-resistant Plasmodium falciparum V1S strain, suggesting that QN254 could be used to treat malaria in regions with a high prevalence of antifolate resistance. Here, we further demonstrate that QN254

An increase in risk of Plasmodium vivax malaria in early childhood resulting in a cross-species protection against severe P. falciparum malaria has been proposed as a possible mechanism in Melanesian [...] wild-type allele. No significant differences in the incidence of P. falciparum (Pf) or P. vivax (Pv) malaria were observed between alpha(+)-thalassemia homozygote (Pf: Incidence rate ratio (IRR) = 1.13, CI(95) [...] = 0.008). This study therefore failed to confirm an increased risk of...
Attrition, physical integrity and insecticidal activity of long-lasting insecticidal nets in sub-Saharan Africa and modelling of their impact on... (Publications)
and killing effects of LLINs on both susceptible and pyrethroid resistant malaria vectors to estimate the protection against malaria transmission-in terms of vectorial capacity (VC)-provided by each net cohort [...] BACKGROUND: Long-lasting insecticidal nets (LLINs) are the primary malaria prevention and control intervention in many parts of sub-Saharan Africa. While LLINs are expected to last at least 3 years under [...] contributions of these different interrelated factors to durability of...

The presented data also demonstrate that clinical study sites in malaria endemic regions need to have a strong malaria diagnostic infrastructure, including the ability of capturing sub-microscopic [...] BACKGROUND: Malaria is endemic in Tanzania with majority of clinical cases caused by Plasmodium falciparum. Additionally, Plasmodium malariae and Plasmodium ovale spp. are also present and clinical ma [...] P. malariae infections that were identified during a clinical trial evaluating...

However, knowledge [...] falciparum apical membrane antigen 1 (AMA1) is an important target of naturally-acquired antibodies in malaria immunity and a leading vaccine candidate. However, AMA1 has extensive allelic diversity with more [...] single population. Therefore, AMA1 serves as an excellent model to assess...
