Abs that inhibit Plasmodium falciparum invasion of erythrocytes form an important component of human immunity against malaria, but key target Ags are largely unknown. Phenotypic variation by P. falciparum mediates the evasion of inhibitory Abs, contributing to the capacity of P. falciparum to cause repeat and chronic infections. However, Ags involved in mediating immune evasion have not been de...

There exists great disparity in the number of clinical P. falciparum episodes among children of the same age and living in similar conditions. The epidemiological determinants of such disparity are unclear. We used a data-mining approach to explore a nineteen-year longitudinal malaria cohort study dataset from Senegal and identify variables associated with increased risk of malaria episodes. Th...

Malaria is one of the most widespread infectious diseases of tropical countries with an estimated 207 million cases globally. In India, there are endemic pockets of this disease, including Aligarh. Hundreds of Plasmodium falciparum and P. vivax cases with severe pathological conditions are recorded every year in this district. The aim of this study is to find out changes in liver enzymes and ki...

Recent studies using laboratory clones have demonstrated that several antiretroviral protease inhibitors (PIs) inhibit the growth of Plasmodium falciparum at concentrations that may be of clinical significance, especially during human immunodeficiency virus type 1 (HIV-1) and malaria coinfection. Using clinical isolates, we now demonstrate the in vitro effectiveness of two HIV-1 aspartic PIs, s...

BACKGROUND AND OBJECTIVES Glycolysis is the sole source of energy for the intraerythrocytic stages of Plasmodium falciparum, making glycolytic enzymes putative therapeutic targets. Enolase, a single copy gene in P. falciparum is one such enzyme whose activity is elevated approximately 10-15 fold in infected RBC's. It holds the possibility of having multiple biological functions in the parasite ...

background: cerebral malaria (cm) is one of the major causes of death in african populations infected with plasmodium falciparum. only 1% of infected subjects develop cm. the reasons for these differences are not fully understood, but it is likely that the host humoral response against blood-stage antigens plays a role in protection from malaria, although the precise targets and mechanisms medi...

background : the aim of the study was to identify the prevalence of different species of plasmodium and haplotypes of pfcrt in plasmodium falciparum from the selected area. methods : overall, 10,372 blood films of suspected malarial patients were examined microscopically from rural health center sinawan, district muzaffargarh, pakistan from november 2008 to november 2010. p. falciparum positive...

Indirect evidence has suggested the existence of a second chitinase gene, PgCHT2, in the avian malaria parasite Plasmodium gallinaceum. We have now identified PgCHT2 as the orthologue of the P. falciparum chitinase gene PfCHT1, a malaria transmission-blocking target. Computational phylogenetic evidence and biochemical and cell biological functional data support the hypothesis that an avian-rela...

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...

Despite recognition of acute respiratory distress syndrome in both falciparum and vivax malaria, disease-related changes in pulmonary function have not been defined, and underlying mechanisms are not well understood. Respiratory symptoms, pulmonary function, pulmonary phagocytic cell activity, and longitudinal changes were examined in 26 adults with uncomplicated falciparum, vivax, and ovale ma...
