Terminalia albida (Combretaceae), widely used in Guinean traditional medicine, showed promising activity against Plasmodium falciparum and Candida albicans previous studies. Bioassay-guided fractionation was carried out order to isolate the compounds responsible for these activities. Fractionation isolation were performed by flash chromatography, followed semi-preparative HPLC-DAD-MS. The struc...

Plasmodium falciparum proteasome (Pf20S) inhibitors are active against at multiple stages—erythrocytic, gametocyte, liver, and gamete activation stages—indicating that selective Pf20S possess the potential to be therapeutic, prophylactic, transmission-blocking antimalarials. Starting from a reported compound, we developed noncovalent, macrocyclic peptide inhibitor of malarial with high species ...

circumsporozoite protein (csp) is one of the stage specific antigens, which is used for the development of vaccines and to investigate the genetic diversity in plasmodium falciparum malaria parasite. polymerase chain reaction was used for typing of csp genes on 67 positive falciparum malaria patients from sistan and baluchistan province of iran. three fragments were detected for csp gene. twent...

Sporozoites of Plasmodium falciparum are transmitted to human hosts by Anopheles mosquitoes. Thrombospondin-related adhesive protein (TRAP) is expressed in sporozoites and plays a crucial role in sporozoite gliding and invasion of human hepatocytes. A previous study showed that the TRAP gene has been subjected to balancing selection in the Gambian P. falciparum population. To further study the ...

Malaria vaccines containing the Plasmodium falciparum Circumsporozoite protein repeat domain are undergoing human trials. There is no simple method to evaluate the effect of vaccine-induced responses on P. falciparum sporozoite infectivity. Unlike the rodent malaria Plasmodium berghei, P. falciparum sporozoites do not infect common laboratory animals and only develop in vitro in human hepatocyt...

We conducted this study to determine if the finding of schizontemia could be used as an indicator of severe falciparum malaria. We enrolled 250 patients with severe falciparum malaria and 250 patients with umcomplicated falciparum malaria into the study. Severe falciparum malaria was defined following World Health Organization criteria (2010). Of the 250 patients with severe falciparum malaria,...

BACKGROUND Malaria is a major public health problem in the malaria endemic zones of the world. Various factors influence the prevalence of malaria. This study was conducted to determine the variation in frequency of Plasmodium vivax and Plasmodium falciparum malaria in different seasons of the year in Khyber Teaching Hospital, Peshawar. METHODS A total of 411 patients were included in the stu...

Plasmodium falciparum and P. malariae occur endemically in many parts of Africa. Observations from malariotherapy patients suggest that co-infection with P. malariae may increase P. falciparum gametocyte production. We determined P. falciparum gametocyte prevalence and density by quantitative nucleic acid sequence-based amplification (QT-NASBA) after antimalarial treatment of Kenyan children wi...

background over the past years, the malaria elimination program has considerably decreased the malaria indigenous cases and confined their incidence to the southeastern areas of iran encompassing 28 less developed counties with favorable transmission conditions. objectives the aim of the study was to investigate the effects of climatic and socioeconomic indicators on malaria transmission and to...

objectives: malaria is the most important tropical disease in terms of morbidity and mortality. the diagnosis of malaria can be conveniently subdivided into clinical, parasitological, biochemical, serological and molecular biological detection. the objective of the present work was to compare two techniques, blood smear and pcr-rflp, for detection of plasmodium species. materials & method...
