Background. Malaria is a one of the leading causes of morbidity and mortality in tropical countries. Plasmodium vivax (P. vivax) is usually thought to be causing benign malaria with low incidence of complications as compared to Plasmodium falciparum (P. falciparum). Methods. This retrospective observational study included malaria patients who were admitted to K.T. Children Hospital and P.D.U. G...

INTRODUCTION In remote areas of the Amazon Region, diagnosis of malaria by microscopy is practically impossible. This study aimed to evaluate the performance of two rapid diagnostic tests (RDTs) targeting different malaria antigens stored at room temperature in the Brazilian Amazon Region. METHODOLOGY Performance of the OptiMal Pf/Pan test and ICT-Now Pf/Pan test was analyzed retrospectively ...

BACKGROUND In the majority of health centers in Ethiopia, the severity of falciparum malaria has been determined by parasitemia alone. However, it has been suggested that the use of peripheral infected RBC counts as an indicator of disease severity by itself is insufficient. Therefore, this study was performed to assess the severity of falciparum malaria infection in three Ethiopian localities ...

BACKGROUND Naturally acquired immunity to malaria may be lost with lack of exposure. Recent heterogeneous reductions in transmission in parts of Africa mean that large populations of previously protected people may lose their immunity while remaining at risk of infection. METHODS Using two ethnically similar long-term cohorts of children with historically similar levels of exposure to Plasmod...

BACKGROUND The efficient allocation of financial resources for malaria control using appropriate combinations of interventions requires accurate information on the geographic distribution of malaria risk. An evidence-based description of the global range of Plasmodium falciparum malaria and its endemicity has not been assembled in almost 40 y. This paper aims to define the global geographic dis...

In the present study, we have tried to establish continuous cultures of fresh clinical isolates of P. falciparum by using a serum-free medium, GIT. To examine the ability of GIT to support the parasite growth, the growth of various P. falciparum isolates including two laboratory strains of P. falciparum, FCR3 and K1 was compared in both of GIT and RPMI 1640 medium supplemented by 10% human seru...

background: pfmdr1 and its variants are molecular marker which are responsible for antibiotics resistance in plasmodium falciparum, a parasitic carrier for malaria dis-ease. a novel strategy to treat malaria disease is by disrupting parasite lactate dehy-drogenase (pldh), a crucial enzyme for plasmodium survival during their erythro-cytic stages. this research was aimed to investigate and chara...

background: falciparum malaria is a severe health burden worldwide. antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. malarial hemozoin (hz), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. objective: to determine the immunological impact of hemozoin on the capacity ...

Drug-resistant Plasmodium falciparum is present in Vietnam. We assessed the in vivo sensitivity of P. falciparum to halofantrine in two villages in the southern part of central Vietnam. Halofantrine (8 mg/kg x 3 doses) was administered to 37 patients with either P. falciparum (n = 32) or mixed P. falciparum/P. vivax malaria (n = 5). End points were parasite sensitivity or resistance (RI/RII/RII...

A neural network approach for the prediction of mitochondrial transit peptides (mTPs) from the malaria-causing parasite Plasmodium falciparum is presented. Nuclear-encoded mitochondrial protein precursors of P. falciparum were analyzed by statistical methods, principal component analysis and supervised neural networks, and were compared to those of other eukaryotes. A distinct amino acid usage ...
