Only Few Seabird Species Contract Avian Malaria

Climate differences have less impact on the transmission of blood parasites than expected Seabirds often live in large colonies in very confined spaces. Parasites, such as fleas and ticks, take advantage of this ideal habitat with its rich supply of nutrition. As a result, they can transmit blood parasites like avian malaria to the birds. Scientists from the Max Planck Institute for Ornithology in Radolfzell and a team of international colleagues have investigated whether this affects all...

An antimalarial agent developed by researchers at Albert Einstein College of Medicine of Yeshiva University proved effective at clearing infections caused by the malaria parasite most lethal to humans — by literally starving the parasites to death. The novel research, carried out on a small number of non-human primates, could bolster efforts to develop more potent therapies against one of the world's leading killers. The study, published in the November 11, 2011 issue of PLoS ONE, was...

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...

Breakthrough In The Battle Against Malaria

Study identifies new ways to kill the human malaria parasite, Plasmodium falciparum An international team of scientists has announced a breakthrough in the fight against malaria, paving the way for the development of new drugs to treat the deadly disease. According to the World Health Organisation malaria currently infects more than 225 million people worldwide and accounts for nearly 800,000 deaths per year. Most deaths occur among children living in Africa where a child dies every 45...

New class of compounds would target earliest stages of infection Researchers have discovered a group of chemical compounds that might one day be developed into drugs that can treat malaria infection in both the liver and the bloodstream. The study, which appears in the Nov. 18 issue of Science, was led by Elizabeth A. Winzeler, Ph.D., of the Scripps Research Institute in La Jolla, Calif., and was partially funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of...

Findings point to the development of novel drugs that could eradicate the disease A international team led by scientists from the Genomics Institute of the Novartis Research Foundation (GNF) and The Scripps Research Institute has discovered a family of chemical compounds that could lead to a new generation of antimalarial drugs capable of not only alleviating symptoms but also preventing the deadly disease. In a study published November 17, 2011, in Science Express, the advance online...

A study conducted by researchers at the Johns Hopkins Malaria Research Institute and their Zambian colleagues detected contrasting patterns of drug resistance in malaria-causing parasites taken from both humans and mosquitoes in rural Zambia. Parasites found in human blood samples showed a high prevalence for pyrimethamine-resistance, which was consistent with the class of drugs widely used to treat malaria in the region. However, parasites taken from mosquitoes themselves had very low...

Malaria Parasite Discovery May Lead To Vaccine
2011-11-10 14:08:10

[ Watch the Video ] Researchers have revealed a new discovery in understanding how a malaria parasite invades human red blood cells. The team from the Wellcome Trust Sanger Institute said they found that the parasite relies on a single receptor on the red blood cell's surface to invade. Malaria kills about a million people every year, most of them being children in Africa under the age of five. The blood stage of the parasite's lifecycle starts when it invades human red blood...

Image 1 - Which Came First? Humans Or Malaria?

Malaria Revealed As Ancient, Adaptive And Persistent Foe One of the most comprehensive analyses yet done of the ancient history of insect-borne disease concludes for the first time that malaria is not only native to the New World, but it has been present long before humans existed and has evolved through birds and monkeys. The findings, presented in a recent issue of American Entomologist by researchers from Oregon State University, are based on the study of insect specimens preserved...
