Emergence of resistance to the drug artemisinin in western Thailand has created a critical point in global efforts to control and eliminate malaria worldwide, according to a new study published in the Lancet, a British Medical Journal, by researchers at the Texas Biomedical Research Institute and their collaborators in Thailand. A second study, published concurrently in the journal Science by the same research groups, identifies a major region of the malaria parasite genome associated with...

Scientists from the University of Liverpool are working with computer modeling specialists in India to predict areas of the country that are at most risk of malaria outbreaks, following changes in monsoon rainfall. The number of heavy rainfall events in India has increased over the past 50 years, but research has tended to focus on the impact this has on agriculture rather than the vector-borne diseases, such as malaria and Japanese Encephalitis. The University's School of Environmental...

Malaria infections among infants can be cut by up to 30 per cent when antimalarial drugs are given intermittently over a 12 month period, a three-year clinical trial in Papua New Guinea has shown. The trial showed the drug regime was effective against both Plasmodium falciparum and Plasmodium vivax malaria, the first time antimalarial drugs have been shown to prevent infections by both species of malaria. The treatment regime, called intermittent preventive treatment (IPT), protected the...

Research: Risk factors for mortality from imported falciparum malaria in the UK over 20 years: An observational study Tourists who have visited a malaria-infected country and are over the age of 65 are almost 10 times more likely to die from the disease than those who are aged 18-35, reveals a study published on bmj.com today. The death rate among tourists is particularly high when returning from a 'winter sun' holiday in the Gambia, West Africa. Authors from the London School of...

A three-arm randomized trial conducted by Ivo Mueller of the Papua New Guinea Institute of Medical Research, Madang, Papua New Guinea, and colleagues among infants in Papua New Guinea estimates the preventive effect against malaria episodes of intermittent preventive treatment, in an area where children are exposed to both falciparum and vivax malaria. Their findings, published in this week's PLoS Medicine, show that intermittent preventive treatment given during infancy at the time of...

Scientists have discovered a new target in their fight against the devastating global disease 'malaria' thanks to the discovery of a new protein involved in the parasite's life cycle. The research has uncovered a vital player in the sexual phase of the malaria parasite's reproduction which could prove an effective target for new treatments to stop the disease in its tracks. The scientists from The University of Nottingham's School of Biology, with collaborators from the Universities of...

In this week's PLoS Medicine, Michael Delves of Imperial College London, UK and colleagues compare the activity of 50 current and experimental antimalarials against liver, sexual blood, and mosquito stages of selected human and nonhuman parasite species, including Plasmodium falciparum, Plasmodium berghei, and Plasmodium yoelii. These results provide a valuable guide to help researchers decide which drugs and compounds show most promise as potential future antimalarial drugs for blocking the...

New research from the University of Melbourne shows how the malaria parasite (Plasmodium falciparum) changes into a banana shape before sexual reproduction, a finding that could provide targets for vaccine or drug development and may explain how the parasite evades the human immune system. The work was conducted by an Australian research team led by Dr Matthew Dixon and PhD student Megan Dearnley from the Department of Biochemistry and Molecular Biology, Bio21 Institute at the University...

A study of almost 3,800 pregnancies has provided the most accurate and direct evidence to date that malaria infection reduces early foetal growth. Low birth weight is the most important risk factor for neonatal mortality in developing countries. The research, carried out on the border of Thailand and Myanmar (Burma), highlights the importance of preventing malaria in pregnancy. According to the World Malaria Report 2011, malaria killed an estimated 655,000 people in 2010. It is caused by...
