Genetics study identifies key genome region underlying artemisinin resistance in malaria parasite Evidence that the most deadly species of malaria parasite, Plasmodium falciparum, is becoming resistant to the front line treatment for malaria on the border of Thailand and Myanmar (Burma) is reported in The Lancet today. This increases concern that resistance could now spread to India and then Africa as resistance to other antimalarial drugs has done before. Eliminating malaria might then...

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...

Researchers compare the genome of 2 parasites to explain differences in host range and transmission strategy Researchers have found the subtle genetic differences that make one parasite far more virulent than its close relative. They looked at the evolution of these parasites and found that although their genome architecture still remains similar, the two split from their common ancestor 28 million years ago, approximately four times longer than the human-gorilla split. Toxoplasma is...

The parasite Toxoplasma gondii has some favorable effects on the pathogenesis and progression of a mouse model of Alzheimer's disease, reports a Mar. 21 study in the open access journal PLoS ONE. Toxoplasma gondii, a parasite commonly hosted in cats and generally known for the potential complications it can cause for human pregnancies, suppressed the immune system. The researchers behind today's study, led by Eun-Hee Shin of the Seoul National University College of Medicine, found that...
