Their finding challenges the widely-accepted theory that Plasmodium falciparum, which causes the most lethal form of malaria, is the only malaria parasite capable of driving genome evolution in humans. The study was published today in the journal PLOS Medicine. Professor Ivo Mueller from the Walter and Eliza Hall Institute and Barcelona Centre for International Health Research (CRESIB) led the study, with colleagues from the Papua New Guinea Institute of Medical Research, Centre of Global...

A novel technique to "tame" the malaria parasite, by forcing it to depend on an external supply of a vital chemical, has been developed by researchers at the Stanford University School of Medicine and the University of California-San Francisco. The scientists have, in effect, created a domesticated strain of Plasmodium – the one-celled parasite that causes malaria – that would no longer cause this dreaded disease. Their findings not only make it possible to grow large volumes...

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...

New treatments for malaria are possible after Walter and Eliza Hall Institute scientists found that molecules similar to the blood-thinning drug heparin can stop malaria from infecting red blood cells. Malaria is an infection of red blood cells that is transmitted by mosquitoes. The most common form of malaria is caused by the parasite Plasmodium falciparum which burrows into red blood cells where it rapidly multiplies, leading to massive numbers of parasites in the blood stream that can...

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...

UCI, French finding could complicate quest to eradicate deadly disease in humans The parasite that causes malignant malaria in humans has been detected in gorillas, along with two new species of malaria parasites, reports a study co-authored by UC Irvine biologist Francisco Ayala. The study also confirms a recent discovery by Ayala and colleagues that human malignant malaria, caused by Plasmodium falciparum, originated from a closely related parasite found in chimpanzees in equatorial Africa....

Walter and Eliza Hall Institute researchers have uncovered a group of proteins that could form the basis of an effective vaccine against malaria. Presently there is no malaria vaccine available, and these new findings support the development of a vaccine against the blood-stage of malaria. Malaria is an infection of blood cells and is transmitted by mosquitoes. The most common form of malaria is caused by the parasite Plasmodium falciparum. Malaria parasites burrow into red blood cells by...

New research has shown that an emerging new form of malaria caused by the parasite Plasmodium knowlesi, originally believed to only infect monkeys, also poses a deadly threat to humans, BBC News reported. It has been found to be widespread in humans in Malaysia and the international team of experts says it can be deadly if it is not quickly treated. So far the new form of the disease has been concentrated in South East Asia, but researchers warned that Western countries could soon see new...

Amplifying entire mitochondrial genomes yields new insight into evolution of malaria Even though the most deadly form of malaria for humans, Plasmodium falciparum, has been linked to malaria found in chimpanzees, this group has been fairly isolated on the malarial family tree "” until now. A new phylogenetic analysis from the Sackler Institute for Comparative Genomics at the American Museum of Natural History reveals that malarial parasites found in tree-dwelling rats share a close...

A U.S.-led team of scientists has identified the complete genetic sequence of a parasite that is the leading cause of relapsing malaria. Working at The Institute for Genomic Research/J. Craig Venter Institute in Rockville, Md., the scientists studied the parasite Plasmodium vivax. Unlike three other species of Plasmodium that cause malaria, the researchers said P. vivax cannot be grown in the laboratory, severely limiting its scientific study. "Completion of the P. vivax genome promises to...
