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
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

Limited antigenic diversity of <em>Plasmodium falciparum</em> apical membrane antigen 1 supports the development of effective multi-allele vaccines (Publications)
evasion used by many important pathogens, and presents major challenges in vaccine development. In malaria, many key immune targets and vaccine candidates show substantial polymorphism. 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...
Semi-field evaluation of a volatile transfluthrin-based intervention reveals efficacy as a spatial repellent and evidence of other modes of action (Publications)
Presently, the most common malaria control tools-i.e., long lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS)-are limited to targeting indoor biting and resting behaviors of Anopheles [...] Anopheles mosquito species. Few interventions are targeted towards malaria control in areas where transmission is driven or persists due to outdoor biting behaviors. This study investigated a volatile [...] Southern Province, Zambia, is one such environment where outdoor biting is...
