Quality control of long-lasting insecticidal nets: are we neglecting it? (Publications)
long-lasting insecticidal nets (LLINs) for malaria control have been delivered to recipient countries. LLINs are the largest single item in the global malaria control budget. To be eligible for donor-funded

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

Previous World Health [...] more accurate but will likely rise twofold due to better detection of treatment failures, and the malaria community needs to anticipate and prepare for potentially large increases in estimated failure rates
The use of the polymerase chain reaction for more sensitive detection of <em>Plasmodium falciparum</em> (Publications)
The prevalence of Plasmodium falciparum in children and adults living in a malaria-endemic area in Papua New Guinea was determined by microscopy and by polymerase chain reaction (PCR). The sensitivity [...] infection remained undetected by microscopy. The introduction of PCR has opened up new possibilities in malaria diagnosis and research.
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

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...

We have designed a multiwell microarray that is used in conjunction with PCR-amplified target genes implicated in the drug resistance of malaria with subsequent [...] by RFLP of mixed infections. The system is sufficiently sensitive to assay parasites in clinical malaria cases and in most asymptomatic cases, and it allows high throughput with minimal hands-on time. The
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
