Contrasting genomic epidemiology between sympatric <em>Plasmodium falciparum</em> and <em>Plasmodium vivax</em> populations (Publications)
The malaria parasites Plasmodium falciparum and Plasmodium vivax differ in key biological processes and associated clinical effects, but consequences on population-level transmission dynamics are difficult [...] difficult to predict. This co-endemic malaria study from Guyana details important epidemiological contrasts between the species by coupling population genomics (1396 spatiotemporally matched parasite genomes [...] uniquely to selected demographics. We discuss possible underlying...
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

We will recruit malaria patients (uncomplicated and severe) and asymptomatic carriers with a positive malaria rapid diagnostic test (RDT), over a two-year period at [...] Background: Malaria is a major public health problem globally and resistance to most widely used drugs impedes its control. Artemisinin resistance has emerged and spread in the Greater Mekong Sub region [...] factors that have led to the emergence of artemisinin resistance in Rwanda ยท...
Probing <em>Plasmodium falciparum</em> sexual commitment at the single-cell level (Publications)
Background: Malaria parasites go through major transitions during their complex life cycle, yet the underlying differentiation pathways remain obscure. Here we apply single cell transcriptomics to unravel [...] programs, with important implications for our understanding of parasite biology and the ongoing malaria elimination campaign.
