چکیده

There is now a growing body of evidence that challenges the current view that Plasmodium vivax-infected erythrocyte (Pv-iE) are unable to sequester. Here we used ex vivo adhesion assays with Pv-iE before and after maturation to demonstrate a higher binding potential of schizonts compared to other asexual stages. These experimental results are correlated with our observations in a panel of 50 vivax malaria patients where schizonts were completely absent in 27 isolates, and few schizonts were observed in the remaining patients. These observations prompt a paradigm shift in P. vivax biology and open avenues to investigate the role of Pv-iE sequestration.

Identification of proteins from Plasmodium falciparum that are homologous to reticulocyte binding proteins in Plasmodium vivax.

Plasmodium falciparum infections can be fatal, while P. vivax infections usually are not. A possible factor involved in the greater virulence of P. falciparum is that this parasite grows in red blood cells (RBCs) of all maturities whereas P. vivax is restricted to growth in reticulocytes, which represent only approximately 1% of total RBCs in the periphery. Two proteins, expressed at the apical...

Characteristics of Plasmodium vivax-infected erythrocyte rosettes.

To investigate the rosette formation properties of Plasmodium vivax, blood was sampled from 26 adult Thai patients admitted with acute P. vivax malaria and a predominance of trophozoite and schizont stages in their peripheral blood smears. In each case, P. vivax-infected cells formed spontaneous rosettes with two or more uninfected red blood cells. Rosette formation of P. vivax was dependent on...

First Report of Neutrophil Involvement of Exflagellated Plasmodium vivax Microgametes

Dear editor Malarial infections pass through multiple stages, beginning in the hepatic parenchymal cells where invading sporozoites mature into schizonts. On maturation, these schizonts rupture and release merozoites into the bloodstream, which, in turn, target erythrocytes, leading to the clinical manifestations of the disease [1]. Exflagellation is characterized by thin, flagella-shaped micro...

Parasite Biomass-Related Inflammation, Endothelial Activation, Microvascular Dysfunction and Disease Severity in Vivax Malaria

Plasmodium vivax can cause severe malaria, however its pathogenesis is poorly understood. In contrast to P. falciparum, circulating vivax parasitemia is low, with minimal apparent sequestration in endothelium-lined microvasculature, and pathogenesis thought unrelated to parasite biomass. However, the relationships between vivax disease-severity and total parasite biomass, endothelial autocrine ...

In-vitro activity of primaquine against the asexual blood stages of Plasmodium falciparum

Primaquine, an 8-aminoquinoline, has been shown to inhibit the development of the hepatic stages (hypnozoites and schizonts), gametocytes, and asexual, intra-erythrocytic forms of malarial parasites (Peters and Robinson, 1987). This triple action is unique among antimalarial drugs. Primaquine is widely used for its anti-hypnozoite action (i.e. to prevent relapses of Plasmodium vivax or P. ovale...
