This study evaluated the haematological profile of adult individuals infected with the malaria parasite. Methods: A retrospective study was conducted using archived data of malaria positive cases from January 2017 to March 15, 2019. Data retrieved included subjects' demographics, malaria parasite count, malaria parasite species, and full blood count parameters. A total of 236 malaria positive subjects were included in the study. Results: The study showed that more females were infected with the malaria parasite than males (69.07% and 30.93%, respectively). A total of 87.3% of the study population were infected with...

Malaria is one of the three most lethal infectious diseases. Unlike AIDS and tuberculosis, malaria is unique in that the parasite must complete a complex differentiation program in its mosquito vector for transmission to occur (1) (Fig. 1). Despite significant progress made in the last couple of decades, our mechanistic...

Authors: Lambraño J, Curtidor H, Avendaño C, Díaz-Arévalo D, Roa L, Vanegas M, Patarroyo ME, Patarroyo MA Abstract Malaria continues being a high-impact disease regarding public health worldwide; the WHO report for malaria in 2018 estimated that ~219 million cases occurred in 2017, mostly caused by the parasite Plasmodium falciparum. The disease cost the lives of more than 400,000 people, mainly in Africa. In spite of great efforts aimed at developing better prevention (i.e., a highly effective vaccine), diagnosis, and treatment methods for malaria, no efficient solution to this disease ...

Contributors : Maria Toro-Moreno ; Kayla SylvesterSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiens ; Plasmodium bergheiThe apicomplexan parasites Plasmodium spp. are the causative agents of malaria, a disease that poses a significant global health burden. Plasmodium spp. initiate infection of the human host by transforming and replicating within hepatocytes. Yet, despite the liver stage being a critical step during infection, most transcriptomic studies have focused on more technically accessible stages of the Plasmodium life cycle, limiting our ability to target these parasites to pr...

Abstract Parasitic diseases are a serious public health problem affecting hundreds of millions of people worldwide. African trypanosomiasis, American trypanosomiasis, leishmaniasis, malaria and toxoplasmosis are the main parasitic infections caused by protozoan parasites with over one million deaths each year. Due to old medications and drug resistance worldwide, there is an urgent need for new antiparasitic drugs. 1,3,4-Thiadiazoles have been widely studied for medical applications. The chemical, physical and pharmacokinetic properties recommend 1,3,4-thiadiazole ring as a target in drug development. Many scienti...

Plasmodium spp.-infected mosquitos inject sporozoites into the skin of a mammalian host during a blood meal. These enter the host's circulatory system and establish an infection in the liver. After a silent metamorphosis, merozoites invade the blood leading to the symptomatic and transmissible stages of malaria. The silent pre-erythrocytic malaria stage represents a bottleneck in the disease which is ideal to block progression to clinical malaria, through chemotherapeutic and immunoprophylactic interventions. RTS,S/AS01, the only malaria vaccine close to licensure, although with poor efficacy, blocks the sporozoite invasio...

An acute episode of malaria can be followed by multiple recurrent episodes either due to re-infection, recrudescence of a partially treated parasite or, in the case of Plasmodium vivax or P. ovale, relapse from t...

Severe malaria is mostly caused by Plasmodium falciparum, resulting in considerable, systemic inflammation and pronounced endothelial activation. The endothelium forms an interface between blood and tissue, and vasculopathy has previously been linked with malaria severity. We studied the extent to which the endothelial glycocalyx that normally maintains endothelial function is involved in falciparum malaria pathogenesis by using incident dark-field imaging in the buccal mucosa. This enabled calculation of the perfused boundary region, which indicates to what extent erythrocytes can permeate the endothelial glycocalyx. The ...
