Plasmodium vivax can cause severe malaria, however its pathogenesis is poorly understood. In contrast to P. falciparum, circulating vivax parasitemia is low, with minimal apparent sequestration in endothelium-lined microvasculature, and pathogenesis thought unrelated to parasite biomass. However, the relationships between vivax disease-severity and total parasite biomass, endothelial autocrine ...

background: plasmodium vivax is the most widespread species of plasmodium in humans and causing about 80 million clinical cases annually. this study was under-taken to detect p. vivax in asymptomatic treated vivax malaria patients to trace la-tent/sub-patent malaria infection. method: the venous blood of all detected cases with p. vivax in bashagard, minab and roodan districts in hormozgan prov...

Malaria therapy, experimental, and epidemiological studies have shown that erythrocyte Duffy blood group-negative people, largely of African ancestry, are resistant to erythrocyte Plasmodium vivax infection. These findings established a paradigm that the Duffy antigen is required for P. vivax erythrocyte invasion. P. vivax is endemic in Madagascar, where admixture of Duffy-negative and Duffy-po...

infection resulting from plasmodium vivax is the commonest type found in india as well as other tropical regions. the clini­cal picture is variable depending on the nature, immunity of the child, and lives in an endemic area or not. here, we report a child, who presented with cerebellar dysfunction with intact sensorium and plasmodium vivax was positive on peripheral smear.

Background: Malaria is still account for 200 million cases annually. Microscopy is the gold standard technique for malaria parasites detection. PCR-based techniques can detect malaria infections with high sensitivity. The study aimed to evaluate the sensitivity of microscopy technique in the detection of P. falciparum and P. vivax, using monoplex real-time PCR, Gezira State, Central Sudan. Met...

Mixed malaria infections, Plasmodium falciparum and P. vivax, are suspected to occur at a greater frequency than is detected by conventional light microscopy. In order to determine the year round pattern of transmission and the frequency of mixed infections in malaria endemic area, we carried out a prospective comparison of diagnosis by conventional light microscopy and nested PCR in Chahbahar ...

The ability of the malaria parasite Plasmodium vivax to invade erythrocytes is dependent on the expression of the Duffy blood group antigen on erythrocytes. Consequently, Africans who are null for the Duffy antigen are not susceptible to P. vivax infections. Recently, P. vivax infections in Duffy-null Africans have been documented, raising the possibility that P. vivax, a virulent pathogen in o...

مالاریا یکی از مهمترین بیماریهای انگلی در جهان محسوب می گردد. مقاومت انگلهای plasmodium falciparum و plasmodium vivax به داروهای ضد مالاریایی، افزایش مقاومت پشه های آنوفل به حشره کشها، جابجایی جمعیت و تغییرات آب و هوایی، منجر به بازپدیدی مالاریا در جهان شده است. این عوامل نشان دهنده نیاز به تولید یک واکسن مالاریایی موثر در کنار سایر روشهای کنترلی جهت حذف این بیماری می باشند. اگرچه آنتی ژنهای کا...

Sulfadoxine is predominantly used in combination with pyrimethamine, commonly known as Fansidar, for the treatment of Plasmodium falciparum. This combination is usually less effective against Plasmodium vivax, probably due to the innate refractoriness of parasites to the sulfadoxine component. To investigate this mechanism of resistance by P. vivax to sulfadoxine, we cloned and sequenced the P....

A total of 509 Anopheles Stephensi and 20 Anopheles Culicifacies mosquitoes were collected during two seasonal activity peaks (June, July, August and September) in the years 2000 and 2001, from 36 localities around Minab, Iranshahr and Kahnouj cities. The identity of specimens was confirmed using Shahgodian PAN morphological key. DNA was extracted from the head and thorax of all specimens and s...
