Falciparum malaria is a protozoan disease caused by Plasmodium falciparum transmitted by the bite of infected Anopheles mosquitoes. This is a very common disorder in the tropics associated with myriad complications. We are presenting here acute pancreatitis as a sole presentation in a 35-yr old tribal man infected with falciparum malaria with high parasitemia. Acute pancreatitis is a well-known...

Plasmodium falciparum invades erythrocytes through multiple ligand-receptor interactions, with redundancies in each pathway. One such alternate pathway is the trypsin-resistant pathway that enables P. falciparum to invade trypsin-treated erythrocytes. Previous studies have shown that this trypsin-resistant pathway is dependent on glycophorin B, as P. falciparum strains invade trypsin-digested g...

BACKGROUND Resistance of antimalarial drugs to Plasmodium falciparum has become a major concern in malaria eradication. Although it is also affected by several socioeconomic factors, a new antiplasmodial agent is needed for a global malaria control program. OBJECTIVE In this study, we attempted to uncover the antiplasmodial properties of Garcinia celebica, an Indonesian medicinal plant, along...

BACKGROUND Heterozygous states of hemoglobin (Hb) A and HbS (HbAS, sickle-cell trait) or HbC (HbAC) protect against Plasmodium falciparum malaria by unclear mechanisms. Several studies suggest that HbAS and HbAC accelerate the acquisition of immunity to malaria, possibly by enhancing P. falciparum-specific antibody responses. METHODS We used a protein microarray representing 491 P. falciparum...

The antifolate drugs sulfadoxine and pyrimethamine are commonly used to treat Plasmodium falciparum malaria. However, they can also affect the Plasmodium vivax parasite if it coexists with P. falciparum, as both species have common drug targets. Resistance to the antifolate drugs arises due to point mutations in the target enzymes of the respective parasite. To assess the cross-species impact o...

In this report and (R. Schmidt-Ullrich, L. H. Miller, and D. F. H. Wallach. Manuscript in preparation.), we have demonstrated that malaria proteins on the surface of merozoites and infected erythrocytes cross-react between at least two primate malarias, Plasmodium knowlesi and P. falciparum. Sera from five Gambian adults who were highly immune to P. falciparum were used as a reagent to study th...

BACKGROUND It has been suggested that Schistosoma infection may be associated with Plasmodium falciparum infection or related reduction in haemoglobin level, but the nature of this interaction remains unclear. This systematic review synthesized evidence on the relationship of S. haematobium or S. mansoni infection with the occurrence of P. falciparum malaria, Plasmodium density and related redu...

Plasmodium falciparum invasion of host erythrocytes is essential for the propagation of the blood stage of malaria infection. Additionally, the brief extracellular merozoite stage of P. falciparum represents one of the rare windows during which the parasite is directly exposed to the host immune response. Therefore, efficient invasion of the host erythrocyte is necessary not only for productive...

This study has evaluated Immunochromatographic test (ICT) as a new diagnostic technique, recently introduced in the Sudan for the detection of Plasmodium falciparum (P. falciparum) parasite. A total of one hundred blood samples were examined using ICT in comparison with the traditional microscopic method. All samples were found to be positive for P. falciparum when stained by Giemsa stain and e...

Plasmodium falciparum malaria merozoites require erythrocyte sialic acid for optimal invasion of human erythrocytes. Since mouse erythrocytes have the form of sialic acid found on human erythrocytes (N-acetyl neuraminic acid), mouse erythrocytes were tested for invasion in vitro. The Camp and 7G8 strains of P. falciparum invaded mouse erythrocytes at 17-45% of the invasion rate of human erythro...
