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...

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 ...

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...

Antibodies (Abs) are critical for immunity to malaria. However, Plasmodium falciparum specific Abs decline rapidly in absence of reinfection, suggesting impaired immunological memory. This study determines whether residents of Sweden that were treated for malaria following international travel maintained long-lasting malaria-specific Abs and memory B cells (MBCs). We compared levels of malaria-...

Merozoite surface proteins of Plasmodium falciparum play a critical role in the invasion of human erythrocytes by the malaria parasite. Here we describe the identification of a novel protein with a molecular mass of 40 kDa that is found on the merozoite surface of P. falciparum. We call this protein merozoite surface protein 4 (MSP-4). Evidence for the surface location of MSP-4 includes (i) a s...
