The emergence of artemisinin-resistant Plasmodium falciparum malaria is a major threat to malaria elimination. New tools for supporting the surveillance of artemisinin resistance are critical for current and future malaria control and elimination strategies. We have developed an open-access, user-friendly, web-based tool to analyse parasite clearance half-life data of P. falciparum infected pat...
BACKGROUND Mortality from severe pediatric falciparum malaria appears low in Oceania but Plasmodium vivax is increasingly recognized as a cause of complications and death. The features and prognosis of mixed Plasmodium species infections are poorly characterized. Detailed prospective studies that include accurate malaria diagnosis and detection of co-morbidities are lacking. METHODS AND FINDI...
To understand the effect of previous malaria exposure on antiparasite immune responses is important for developing successful immunization strategies. Controlled human malaria infections (CHMIs) using cryopreserved Plasmodium falciparum sporozoites provide a unique opportunity to study differences in acquisition or recall of antimalaria immune responses in individuals from different transmissio...
Background. People of the Fulani ethnic group are more resistant to malaria compared with genetically distinct ethnic groups, such as the Dogon people, in West Africa, and studies suggest that this resistance is mediated by enhanced antibody responses to Plasmodium falciparum antigens. However, prior studies measured antibody responses to <0.1% of P falciparum proteins, so whether the Fulani m...
To counter the global threat caused by Plasmodium falciparum malaria, new drugs and vaccines are urgently needed. However, there are no practical animal models because P. falciparum infects human erythrocytes almost exclusively. Here we describe a reliable falciparum murine model of malaria by generating strains of P. falciparum in vivo that can infect immunodeficient mice engrafted with human ...
Although the preventive action of dapsone against P. falciparum malaria was known for many years, there was no report about the incidence of P. falciparum malaria in leprosy patients treated with dapsone, especially from areas of Southeast Asia where both leprosy and malaria are endemic. Therefore, two clinic-based malaria surveys were undertaken at a gap of 12 years, comprising 506 lepromatous...
Background: Plasmodiom falciparum MSP-2 is taken into accout as one of the candidates of vaccine agaist malaria and various studies indicated immunizing effect of different domains of the molecule. Monoclonal antibody against MSP-2 is a confident and definite method to confirm this Immunization. Materials and Methods: P. falciparum Parasite was Prepared in a Culture in CludingRPMI1640 and Schi...
The anti-malarial activity of the anti-cancer drug methotrexate against chloroquine-sensitive T9-96 and the multidrug-resistant K1 strains of Plasmodium falciparum was assessed in vitro. Mean IC50 values of 0.32 +/- 0.05 nM and 48.02 +/- 4.40 nM were obtained for T9-96 and K1, respectively, indicating methotrexate's high potency against both sensitive and resistant P. falciparum strains in vitr...
Objective: this study aims to develop a methodology for detecting mutations in the K13 gene and determine mutation frequencies clinical samples. Method: total DNAs were extracted blood samples collected from 50 patients failure with artemisinin treatmentin Central Highlands region. A fragment of was amplified, purified, sequenced by Sanger method. The sequences analysed using Bioedit aligned re...
