Decreased availability of antimalarials in the private sector following the policy change from chloroquine to sulphadoxine-pyrimethamine in the... (Publications)
BACKGROUND: Malaria control strategies emphasize the need for prompt and effective treatment of malaria episodes. To increase treatment efficacy, Tanzania changed its first-line treatment from chloroquine [...] villages with a total population of 13,506 (18%) had neither a health facility, nor a shop as source of malaria treatment. CONCLUSIONS: While the change to SP resulted in a higher treatment efficacy, it also led
<em>Plasmodium vivax</em> antigen discovery based on alpha-helical coiled coil protein motif (Publications)
partial or high alpha-helical content. Antigenicity was evaluated using human sera samples from malaria-endemic areas of Colombia and Papua New Guinea. Eight of these fragments were selected and used to [...] BALB/c mice. ELISA assays indicated strong reactivity of serum samples from individuals residing in malaria-endemic regions and sera of immunized mice, with the alpha-helical coiled coil structures. In addition [...] whole parasites. Results here point to the alpha-helical coiled coil...
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.
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
Case report: Diagnostic challenges in the detection of a mixed <em>Plasmodium vivax/ovale</em> infection in a non-endemic setting (Publications)
In clinical practice, mixed-species malaria infections are often not detected by light microscopy (LM) or rapid diagnostic test, as a low number of parasites of one species may occur. Here, we report the [...] This case demonstrates the significance of molecular testing in the detection of mixed-species malaria infections and highlights the importance of a detailed data analysis during the medical validation

Public-private partnerships aiming to develop new medicines for malaria and sleeping sickness have, over the past 12 years, brought forward several drug candidates that [...] compounds against trypanosomes and other parasites. Thus, finally, new therapeutic agents against malaria and sleeping sickness are within reach
