To compare clinical presentations, haematological and immunological parameters in urban and rural malaria patients. Clinically suspected malaria patients, resident in either rural or urban communities, were selected from seven health facilities in the Greater Accra region of Ghana. For each suspected malaria patient, parasites were detected microscopically and quantified subsequently. In each study site, an equal number of cases and age-matched controls were selected. In both cases and controls, clinical presentations, nutritional status, haematological, and immunological parameters were profiled.
Emerging cases of drug resistance against Artemisinin combination therapies which are the current and the last line of defense against malaria makes the situation very alarming. Due to the liability of single-target drugs to be more prone to drug resistance, the trend of development of dual or multi-target inhibitors is emerging. Recently, a malaria box molecule, MMV007571 which is a well known new permeability pathways inhibitor was investigated to be also multi-targeting Plasmodium falciparum dihydroorotate dehydrogenase and cytochrome bc1 complex.
Despite clinical and pathological distinctions between malaria and hypertension, accumulated epidemiological and evolutionary evidence indicate the need of deeper understanding how severe malaria contributes to elevated hypertension risk. Malaria is said to exert strong selection pressure on the host genome, thus selecting certain genetic polymorphisms.
The genome sequence project of the human malaria parasite Plasmodium falciparum reveal variations in the parasite DNA sequence. Most of these variations are single nucleotide polymorphism (SNP). A high frequency of single nucleotide polymorphism (SNP) in the Plasmodium falciparum population is usually a benchmark for anti-malarial resistance which allows parasites to be elusive to the chemotherapeutic agents, vaccine and vector control strategies, resulting in the leading cause of morbidity and mortality globally.
Plasmodium falciparum malaria causes morbidity and mortality in African children with sickle cell anemia (SCA), but comparisons of host responses to P. falciparum between children with SCA (HbSS) and HbAA are limited. We assessed parasite biomass and plasma markers of inflammation and endothelial activation in children with HbAA (n=208) or HbSS (n=22) who presented with severe anemia and P. falciparum parasitemia to Mulago Hospital in Kampala, Uganda. Genotyping was performed at study completion.
Malaria is the most common parasitic disease around the world, especially in tropical and sub-tropical regions. This parasitic disease can have a rapid and severe evolution. It is transmitted by female anopheline mosquitoes. There is no reliable vaccine or diagnostic test against malaria; instead, Artesunate is used for the treatment of severe malaria and Artemisinin is used for uncomplicated falciparum malaria.
Malaria infection represents a major public health and economic issue that leads to morbidity and mortality globally. A highly effective and uncomplicated detection tool is required for malaria control in geographical hotspots of transmission. We developed a simple and more sensitive novel approach for the detection of the 18S rRNA gene of Plasmodium falciparum based on loop-mediated isothermal amplification (LAMP) and visualization using colorimetric, streptavidin-functionalized gold nanoparticles (SA-GNPs).
Larvicides are typically applied to fixed and findable mosquito breeding sites, such as fish farming ponds used in commercial aquaculture, to kill immature forms and thereby reduce the size of adult malaria vector populations. However, there is little evidence suggesting that larviciding may suppress community-wide malaria transmission outside Africa. Here, we tested whether the biological larvicide VectoMax FG applied at monthly intervals to fish farming ponds can reduce malaria incidence in Amazonian Brazil.
Malaria and typhoid fever are two febrile illnesses prevalent in the tropics that often present overlapping symptoms. In this work, we demonstrate an optical reader-based diagnostics platform for rapid codetection and quantification of two antigen targets: lipopolysaccharide (LPS) for typhoid fever and plasmodium lactate dehydrogenase (pLDH) for malaria infections.
