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...

The aim of this study was to determine the prevalence of malaria infection and antibodies against the repetitive epitopes of the circumsporozoite (CS) proteins of Plasmodium falciparum, P. malariae, P. vivax VK210, P. vivax VK247, and P. vivax-like in individuals living in the states of Rondônia, Pará, Mato Grosso, Amazonas, and Acre. Active malaria transmission was occurring in all studied sit...

A splenectomized aotus monkey infected with human quartan malaria (Plasmodium malariae) developed oedema and proteinuria. Histological examination revealed a generalized diffuse glomerulonephritis and immunofluorescent staining showed granular deposits of IgM in the glomeruli. The pathological picture resembled that shown by human patients with the quartan malaria nephrotic syndrome.

OBJECTIVE To describe the clinical features and management of African migrants recently arrived in Western Australia and subsequently diagnosed with malaria. DESIGN, PARTICIPANTS AND SETTING Retrospective case record analysis of African migrants aged > or = 16 years with malaria referred to Royal Perth Hospital (RPH) from the WA Migrant Health Unit (MHU) between 1 March 2003 and 30 September ...

Molecular diagnosis of malaria offers many potential advantages over microscopy, including identification of malaria to the species level in an era with few experienced microscopists. We developed high-throughput multiplex 5' nuclease quantitative PCR (qPCR) assays, with the potential to support large studies, to specifically identify Plasmodium falciparum, P. vivax, P. ovale, P. malariae, and ...

Malaria is an infectious protozoan parasitic disease transmitted by Anopheles spp mosquito. As a entity, malaria still major global health problem due to its morbidity and mortality that endangered millions of individuals inhabitants in tropical region. Kidney derangement moderately frequent severe caused the species P. falciparum also malariae, but seldom this condition has been reported vivax...

This Atomic Force Microscope image shows the surface of a Plasmodium malariae trophozoite-infected red blood cell isolated from a Burmese patient suffering from quartan malaria (top). Of note, the P. malariae-infected cell (bottom left) is covered with dense ‘spike-like’ excrescences (mean height: 7Æ59 nm; mean diameter: 52Æ95 nm), which are morphologically distinct from the larger, more rounde...

A TaqMan real-time PCR system was used to detect and discriminate the 4 species of human malaria parasites in clinical blood samples. A 150-base pair (bp) region of the small subunit ribosomal RNA (SSU rRNA) gene of each malaria parasite, including species-specific sequences to be detected by TaqMan probe, was used as a target for PCR analysis. The PCR method used universal primers and species-...

To the Editor: A recent article by Zucker (1) described two cases of malaria that were probably transfusion associated. A case of transfusionassociated malaria in which the source was identified was reported in San Francisco in 1991. The case was in an elderly man in whom malaria infection developed after coronary bypass surgery. The patient was born in China and immigrated to the United States...
