abstract       background and objectives: plasmodium falciparum merozoite surface protein-1 (pfmsp-1) is a promising vaccine against malaria during its blood stages which play an important role in immunity to this disease. polymorphic nature of this gene is a major obstacle in making an effective vaccine against malaria. in this study, the genetic diversity of plasmodium falciparum isolates was...

the emergence of plasmodium vivax in dashte moghan in northwestern iran has become a major concern for iranian's health officials. knowledge of genetic make up of the p. vivax populations in this area would give us an insight into the origin of the prevalent infections and the possible routes they are introduced. this paper reports the analysis of a variable region between the two interspecies ...

background: the worldwide distribution of p. vivax has expanded significantly and the number of reported cases has been on the rise. approximately 88% of malaria cases in iran are caused by plasmodium vivax , and in order to management of the disease, understanding the population genetic structure of the parasite is necessary for designing and applying drugs and vaccines. among many potential c...

background: approximately 85-90% of malaria infections in iran are attributed to plasmodium vivax , while little is known about the genetic of the parasite and its strain types in this region. this study was designed and performed for describing genetic characteristics of plasmodium vivax population of iran based on the merozoite surface protein-3α gene sequence. methods: through a descriptive ...

background genetic diversity has provided plasmodium falciparum with the potential capacity of avoiding the immune response, and possibly supported the natural selection of drug or vaccine-resistant parasites. merozoite surface protein-3 (msp-3) has been used to develop vaccines and investigate the genetic diversity regarding p. falciparum malaria in iran. objectives the main goal of this study...

The malaria parasite Plasmodium falciparum replicates within an intraerythrocytic parasitophorous vacuole (PV). Rupture of the host cell allows release (egress) of daughter merozoites, which invade fresh erythrocytes. We previously showed that a subtilisin-like protease called PfSUB1 regulates egress by being discharged into the PV in the final stages of merozoite development to proteolytically...

Oral immunization of mice with Escherichia coli-expressed Plasmodium yoelii merozoite surface protein 4/5 or the C-terminal 19-kDa fragment of merozoite surface protein 1 induced systemic antibody responses and protected mice against lethal malaria infection. A combination of these two proteins administered orally conferred improved protection compared to that conferred by either protein admini...

This study investigated the genetic diversity of Plasmodium falciparum among asymptomatic pregnant women on intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-Sp) in Osogbo, southwest Nigeria. Blood sample was obtained from consenting attending antenatal clinics. Microscopy and Polymerase chain reaction (PCR) were employed to diagnose analyse diversity. Of 301 samples, 53 (1...
