Export of parasite proteins into the host erythrocyte is essential for survival of Plasmodium falciparum during its asexual life cycle. While several studies described key factors within the parasite that are involved in protein export, the mechanisms employed to traffic exported proteins within the host cell are currently unknown. Members of the Hsp70 family of chaperones, together with their ...

BACKGROUND & OBJECTIVE Gametocyte sex-ratio in Plasmodium falciparum malaria is an important determinant of transmission success and basis of disease epidemiology. Information on ratio of male to female gametocytes after an exposure of antimalarial regimens under field conditions is very limited. In this retrospective study we observed high densities of gametocytes along with high sex-ratio in ...

Incomplete malaria control efforts have resulted in a worldwide increase in resistance to drugs used to treat the disease. A complex array of mutations underlying antimalarial drug resistance complicates efficient monitoring of parasite populations and limits the success of malaria control efforts in regions of endemicity. To improve the surveillance of Plasmodium falciparum drug resistance, we...

Background: Malaria is one of the most important infectious diseases in tropical and subtropical regions, 45% population living areas that suffer from stable malaria transmission Sudan. The prevalence symptomatic Plasmodium infection based on microscopy RDTs poorly documented Nyala city. This study was conducted to determine plasmodium molecular identification species city, Sudan.

BACKGROUND In the Peruvian Amazon, Plasmodium falciparum and Plasmodium vivax malaria are endemic in rural areas, where microscopy is not available. Malaria rapid diagnostic tests (RDTs) provide quick and accurate diagnosis. However, pfhrp2 gene deletions may limit the use of histidine-rich protein-2 (PfHRP2) detecting RDTs. Further, cross-reactions of P. falciparum with P. vivax-specific test ...

Glucose stimulates the high-affinity processes of chloroquine and amodiaquin accumulation in owl monkey erythrocytes infected with a chloroquine-susceptible strain of Plasmodium falciparum. Although these erythrocytes have greater ability to accumulate amodiaquin than chloroquine, glucose has relatively less effect on amodiaquin accumulation than on chloroquine accumulation. In contrast to thes...

Plasmodium falciparum causes fatal cerebral malaria and more knowledge is required on its proteome. Proteomic studies require the adaptation of P. falciparum field isolates to continuous in vitro cultivation. The objective of this study is to identify and characterize some of the proteins secreted by P. falciparum trophozoites in the host cell using in vitro conditions. For this purpose, propag...

The present work deals with the development of Plasmodium falciparum stages in mouse model and its potential for the study of efficacy of antimalarial drugs. C57BL/6J mice were infected with multidrug resistant P. falciparum strain then treated with arteether and artesunate. A response was observed to antimalarial drugs in terms of decrease in parasitemia. Mice infected with P. falciparum strai...
