Origin Of Deadly Human Malaria Parasite Linked To Primates In Africa

University of Pennsylvania School of Medicine An international team of scientists has traced the origin of Plasmodium vivax, the second-worst malaria parasite of humans, to Africa, according to a study published this week in Nature Communications. Until recently, the closest genetic relatives of human P. vivax were found only in Asian macaques, leading researchers to believe that P. vivax originated in Asia. The study, led by researchers from the Perelman School of Medicine at the...

Finding has implications for effectiveness of potential vaccines A mutation on the surface of human red blood cells provides protection against malaria caused by the parasite Plasmodium vivax, research led by Case Western Reserve University School of Medicine shows. The minute change, at a single position of red blood cell surface protein called the Duffy blood-group antigen, has been known for years. But the researchers found this difference makes it harder for the parasite to lock...

A new evidence-based global distribution map of Plasmodium vivax malaria, published August 3 in the open-access journal PLoS Neglected Tropical Diseases, is used to estimate that 2.85 billion people lived at risk of infection with this parasite in 2009. The map, created as part of the Malaria Atlas Project (MAP), a multinational research collaboration funded mainly by the Wellcome Trust, reviews a host of information that challenges the dogma that P. vivax transmission is absent through large...

Scientists investigating ovale malaria, a form of the disease thought to be caused by a single species of parasite, have confirmed that the parasite is actually two similar but distinct species which do not reproduce with each other, according to research published in The Journal of Infectious Diseases. Researchers from the London School of Hygiene & Tropical Medicine, the Hospital for Tropical Diseases and Mahidol University, Bangkok collaborated last year in order to share their...

Study proves blood-stage infection due to population mixing and disease evolution In a paradigm changing discovery, Plasmodium vivax (P. vivax) malaria has been identified in a population historically thought to be resistant to the disease, those who do not express the Duffy blood group protein on their red blood cells, according to researchers from Case Western Reserve University School of Medicine, Pasteur Institute, and the Madagascar Ministry of Health. In a study of more than 600...
