background: one of the most important enzymatic disorders that interact with malaria is deficiency of g6pd (gloucose-6-phosphate dehydrogenase). this enzyme protects red blood cells from hydrogen peroxide and other oxidative damages. distribution of this enzyme deficiency usually accompanies with low level distribution of malaria disease in most malarious areas. so this hypothesis may be consid...

background: the recently reported resistance to antimalarials contributes to making the control of ma­laria more difficult. there is a need to evaluate the current antimalaria regimens to prevent this emerging problem. the aim of this study was to determine dihydrofolate reductase-thymidylate synthase gene mu­tation ( pvdhfr ) regarding antifulate resistance in plasmodium vivax . methods : from...

background: plasmodium vivax is the predominant species causes of malaria with about 90% total annual reported malaria in iran. this study conducted to determine the susceptibility of plasmodium vivax isolates to chloroquine in sistan and balochistan province, southeastern iran. methods: a total 270 subjects with symptomatic malaria and confirmed p. vivax infection completed the designed 28-day...

p. vivax malaria with suspected long incubation have been frequently observed mostly in the northwest part of iran in the course of malaria control and malaria eradication operations. a sero-epidemiological study of such cases which present the first symptom in early spring, before anopheles activities season, was carried out in 92 selected villages with a population of 38,726 in two near areas...

The mechanisms of cellular and humoral immune responses against P. vivax parasite remain poorly understood. Several malaria immunological studies have been conducted in endemic regions where both P. falciparum and P. vivax parasites co-exist. In this study, a comparative analysis of immunity to Plasmodium vivax antigens in different geography and incidence of Plasmodium spp. infection was perfo...

The malaria parasite Plasmodium vivax is known to be majorly endemic to Asian and Latin American countries with no or very few reports of Africans infected with this parasite. Since the human Duffy antigens act as receptors for P. vivax to invade human RBCs and Africans are generally Duffy-negative, non-endemicity of P. vivax in Africa has been attributed to this fact. However, recent reports d...

background: malaria is well known for its fatalities worldwide, plasmodium vivax and the plasmodium falciparum are the two important species of malaria reported from pakistan and creating lots of morbidities across the country. method: study was conducted to determine the surveillance of malaria in south punjab by microscopy and polymerase chain reaction (pcr). result : 40 samples out of 100 pa...

detection of plasmodium vivax specific antibodies with serological tests could be a valuable tool for epidemiological researches. whereas p. vivax cannot be simply obtained in vitro, serological tests using total or semi-purified antigens are infrequently used. given this restriction, the present study investigated whether recombinant p. vivax merozoite surface protein 1 (pvmsp-1 42 kda) could ...

BACKGROUND Sub-microscopic (SM) Plasmodium infections represent transmission reservoirs that could jeopardise malaria elimination goals. A better understanding of the epidemiology of these infections and factors contributing to their occurrence will inform effective elimination strategies. While the epidemiology of SM P. falciparum infections has been documented, that of SM P. vivax infections ...
