A new study demonstrates for the first time how the Toxoplasma gondii parasite enters the brain to influence its host's behavior. This research was led by researchers from the Karolinska Institute and Uppsala University in Sweden publishes today in the Open Access journal PLOS Pathogens. The Toxoplasma gondii parasite causes toxoplasmosis. The parasite is common and infects between 30 and 50 per cent of the global population. It also infects animals, especially domestic cats. Human...

How parasites remote control victims Parasites are unpleasant lodgers at the best of times, but there is one group of parasites that is particularly pernicious. These are the parasites that hijack their victims' nervous systems, reducing them to helpless zombies. 'The fact that parasites can so efficiently alter host behaviour is fascinating', says The Journal of Experimental Biology Editor Michael Dickinson, from the University of Washington, USA, adding, 'There is something horrifying...

Northern Spread Of Avian Malaria In Alaska Fueled By Climate Change
2012-09-20 10:40:27

Researchers discover infected birds in Alaska, say global warming will send disease farther north Malaria has been found in birds in parts of Alaska, and global climate change will drive it even farther north, according to a new study published today in the journal PLOS ONE. The spread could prove devastating to arctic bird species that have never encountered the disease and thus have no resistance to it, said San Francisco State University Associate Professor of Biology Ravinder...

Lee Rannals for redOrbit.com — Your Universe Online You may want to start washing your hands after petting fluffy, because new estimates indicate that 350,000 people a year in the United Kingdom become infected with toxoplasmosis. The disease is spread by direct contact with cats, or eating contaminated food, according to a report by the Food Standards Agency. Only about one in 10 of the people who have become infected with toxoplasmosis have symptoms. "The biggest threat is...

When Washington State University and U.S. Department of Agriculture veterinary scientist Don Knowles got word three years ago that a rare but deadly infection was discovered among a group of horses in south Texas, he felt a jolt of adrenaline. Not only were the horses infected with a parasitic disease similar to malaria in humans, but the epicenter of the outbreak was at no ordinary ranch. It was the King Ranch, legendary for its world-class quarter horses, including former winners of the...

Medicines for Malaria Venture has developed a framework to evaluate the risk of resistance for the antimalarial compounds in its portfolio. A paper based on this work: A framework for assessing the risk of resistance for antimalarials in development has been published in the Malaria Journal today. Resistance defines the longevity of every anti-infective drug, so it is important when developing new medicines for malaria, to check how easily promising antimalarial compounds will select for...

Some Suicide Attempts May Be Blamed On Parasite
2012-08-17 15:24:09

Lee Rannals for redOrbit.com — Your Universe Online A parasite may be to blame for some suicide attempts, according to research appearing in the Journal of Clinical Psychiatry. Toxoplasma gondii, or T. gondii, lies in the bodies of 10 to 20 percent of Americans, but in most it was thought to lie dormant. However, it appears as though the parasite can cause inflammation over time, which produces harmful metabolites that can damage brain cells. “Previous research has found...

Interactions Between Malaria Parasite and HIV Demonstrated With Novel Technique
2012-08-16 08:19:05

The World Health Organization estimates that in 2011 there were 216 million cases of malaria and 34.2 million people living with HIV. These diseases particularly afflict sub-Saharan Africa, where large incidence of co-infection result in high mortality rates. Yet, in spite of this global pandemic, interactions between the parasite that causes malaria, Plasmodium falciparum, and HIV-1 are poorly understood. However, a new video article in JoVE, the Journal of Visualized Experiments, that...
