Merozoite surface protein-1 (MSP-1) is one of the several proteins on the surface of the asexual merozoite of malaria parasites. It undergoes a two stage proteolytic cleavage to form a C-terminal 19-kDa fragment or PfMSP119 that is used for red blood cell invasion. A homologue of PfMSP-119 of Plasmodium falciparum called PvMSP-119 has been identified in Plasmodium vivax. Recently, attention has been focused on this...

Predictive parasite density based on a linear regression model obtained from the time of positivity of two malaria rapid diagnostic tests (SD Bioline Malaria Ag-Pf/Pan and Paracheck™-Pf) in Côte d’Ivoire

Rapid diagnostic tests (RDTs) are the current complement to microscopy for ensuring prompt malaria treatment. However, non-estimation of the parasite density is one of the limits of these RDTs. This study aimed to estimate the parasite density based on the time of positivity of two RDTs, SD Bioline Malaria Ag-Pf/Pan and Paracheck™-Pf. A highly parasitized blood sample underwent successive dilutions. On each...
