Malaria remains a major global threat to human health and economic development.
While the importance of understanding human-vector interaction is well-established, relatively few studies have included human behaviour when measuring exposure to malaria vectors.
The present study gave the first molecular evidence of P. vivax in Nigeria in Duffy negative individuals.
In sub-Saharan Africa, inherited causes of anemia are common, but data are limited regarding the geographical prevalence and coinheritance of these conditions and their overall contributions to childhood anemia.
Parasite clearance following treatment with intravenous artesunate was rapid and adequate.
This protocol for high purity high yield B cell and Th cell isolation and sample storage for subsequent qRT-PCR analysis from a minimal amount of blood is contrivable with basic equipment and independent of continuous power supply.
