BACKGROUND Malaria transmission is an extremely complex condition that is manifested differently in different parts of the world. In Pakistan, malaria is still endemic in many areas. Plasmodium vivax and Plasmodium falciparum are identified to be the most prevalent species of malaria in-Pakistan. A great deal of work regarding malarial transmission is available at regional level in Pakistan but...

BACKGROUND Plasmodium vivax is responsible for approximately 80 million malaria cases in the world. Apical membrane antigen1 (AMA-1) is a type I integral membrane protein present in all Plasmodium species. AMA-1 interferes in critical steps of invasion of human hepatocytes by sporozoites and red blood cells by merozoites and is one of the most immunodominant antigens for eliciting a protective ...

Abstract The present research study was aimed to investigate the efficiency of selected medicinal plants against Plasmodium vivax. Crude methanolic extracts from seeds leaves Datura stramonium , Parthenium hysterophorus Calotropis procera and Dodonaea viscosa were prepared. In addition, Atropine also isolated alkaloid components Eucalyptus obliqua evaluate their in vitro anti-plasmodial effects...

The importance of host and parasite genetic factors in malaria resistance or susceptibility has been investigated since the middle of the last century. Nowadays, of all diseases that affect man, malaria still plays one of the highest levels of selective pressure on human genome. Susceptibility to malaria depends on exposure profile, epidemiological characteristics, and several components of the...

BACKGROUND Plasmodium vivax invasion requires interaction between the human Duffy antigen on the surface of erythrocytes and the P. vivax Duffy binding protein (PvDBP) expressed by the parasite. Given that Duffy-negative individuals are resistant and that Duffy-negative heterozygotes show reduced susceptibility to blood-stage infection, we hypothesized that antibodies directed against region tw...

Plasmodium vivax Duffy binding protein (DBP) is a conserved functionally important protein. P. vivax DBP is an asexual blood-stage malaria vaccine candidate because adhesion of P. vivax DBP to its erythrocyte receptor is essential for the parasite to continue development in human blood. We developed a soluble recombinant protein of P. vivax DBP (rDBP) and examined serologic activity to it in re...

BACKGROUND Plasmodium knowlesi is the commonest cause of malaria in Malaysia, but little is known regarding infection during pregnancy. METHODS To investigate comparative risk and consequences of knowlesi malaria during pregnancy, we reviewed (1) Sabah Health Department malaria-notification records created during 2012-2013, (2) prospectively collected data from all females with polymerase cha...

The genome of the malarial parasite Plasmodium falciparum is extremely AT rich. This bias toward a low GC content is a characteristic of several, but not all, species within the genus Plasmodium. We compared 4283 orthologous pairs of protein-coding sequences between Plasmodium falciparum and the less AT-biased Plasmodium vivax. Our results indicate that the common ancestor of these two species ...

Plasmodium falciparum resistance to artemisinin has emerged in the Greater Mekong Subregion and now poses a threat to malaria control and prevention. Recent work has identified mutations in the kelch propeller domain of the P. falciparum K13 gene to be associated artemisinin resistance as defined by delayed parasite clearance and ex vivo ring stage survival assays. Species specific primers for ...

Background Malaria is one of tropical and semi-tropical and vector-borne parasitic diseases produced by the protozoan parasites of the genus and species Plasmodium. The aim of this study was to assess the epidemiology and the factors associated with the malaria in children in Sistan and Baluchistan province in 2013-2016. Materials and Methods This cross-sectional study was conducted between Mar...
