Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi are the parasites that infect humans. Plasmodium falciparum and Plasmodium vivax cause most of the malarial infections worldwide. Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi are susceptible to chloroquine. Chloroquine was the world's most widely used antim...
Background and Aim: Considering the ongoing national malaria elimination program in Iran, establishing a bank of human Plasmodium genes and proteins can be very useful for research purposes. This study was conducted to collect some of the native isolates of human Plasmodia from endemic areas in the country. Materials and Methods: A 2ml vein-punctured blood sample was prepared from each confi...
Background: Malaria is communicable disease that exists worldwide and a cause of morbidity mortality. Our objectives were to determine the prevalence distribution malaria by sex, age groups species in year 2019 suspected malarial population District D.I.Khan, Pakistan.Materials Methods: This cross-sectional study was conducted Department Community Medicine, Gomal Medical College, Pakistan from ...
BACKGROUND Coma complicates Plasmodium falciparum infection but is uncommonly associated with P. vivax. Most series of vivax coma have been retrospective and have not utilized molecular methods to exclude mixed infections with P. falciparum. METHODS We prospectively enrolled patients hospitalized in Timika, Indonesia, with a Glasgow Coma Score (GCS) ≤10 and P. vivax monoinfection on initial m...
BACKGROUND Although Plasmodium vivax infection is a frequent cause of malaria worldwide, severe presentations have been more regularly described only in recent years. In this setting, despite clinical descriptions of multi-organ involvement, data associating it with kidney dysfunction are relatively scarce. Here, renal dysfunction is retrospectively analyzed in a large cohort of vivax malaria p...
In Papua, Indonesia, the antimalarial susceptibility of Plasmodium vivax (n = 216) and P. falciparum (n = 277) was assessed using a modified schizont maturation assay for chloroquine, amodiaquine, artesunate, lumefantrine, mefloquine, and piperaquine. The most effective antimalarial against P. vivax and P. falciparum was artesunate, with geometric mean 50% inhibitory concentrations (IC50s) (95%...
Mutations in the dihydrofolate reductase (dhfr) genes of Plasmodium falciparum and P. vivax are associated with resistance to the antifolate antimalarial drugs. P. vivax dhfr sequences were obtained from 55 P. vivax isolates (isolates Belem and Sal 1, which are established lines originating from Latin America, and isolates from patient samples from Thailand [n = 44], India [n = 5], Iran [n = 2]...
BACKGROUND & OBJECTIVES Traditionally, Plasmodium falciparum has been attributed to cause severe malaria, whereas P. vivax is considered to cause "benign" tertian malaria. Recently, there has been an increasing body of evidence challenging this conviction. However, the spectrum and degree of severity of the disease caused by P. vivax, as per World Health Organization (2012) remains unclear. Thu...
BACKGROUND The undetectable hypnozoite reservoir for relapsing Plasmodium vivax and P. ovale malarias presents a major challenge for malaria control and elimination in endemic countries. This study aims to directly determine the contribution of relapses to the burden of P. vivax and P. ovale infection, illness, and transmission in Papua New Guinean children. METHODS AND FINDINGS From 17 Augus...
Significant progress toward the control of malaria has been achieved, especially regarding Plasmodium falciparum infections. However, the unique biology of Plasmodium vivax hampers current control strategies. The early appearance of P. vivax gametocytes in the peripheral blood and the impossibility of culturing this parasite are major drawbacks. Using blood samples from 40 P. vivax-infected pat...
