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...

Some Suicide Attempts May Be Blamed On Parasite

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...

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences. This precisely focused therapy combines short strands of "antisense" nucleic acid-like...

Common Parasite Of Cat Litter May Increase Suicide Risk In Women

Lawrence LeBlond for redOrbit.com - Your Universe Online What do unwashed vegetables, undercooked meat, and dirty kitty litter all have in common? For one, they are all known to likely harbor a nasty parasite, which in a recent study has been linked as a killer among women who come into contact with the common critter. To be more specific, the parasite -- Toxoplasma gondii -- has been linked with an increased risk of mental health problems and attempted suicide in women who become...

By pairing an intimate knowledge of immune-system function with a deep understanding of statistical physics, a cross-disciplinary team at the University of Pennsylvania has arrived at a surprising finding: T cells use a movement strategy to track down parasites that is similar to strategies that predators such as monkeys, sharks and blue-fin tuna use to hunt their prey. With this new insight into immune-cell movement patterns, scientists will be able to create more accurate models 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...

May bring them into human homes, bridging "infection gap" between people and wildlife Domestic cats, wild bobcats and pumas that live in the same area share the same diseases.  And domestic cats may bring them into human homes, according to results of a study of what happens when big and small cats cross paths. Initial results of the multi-year study are published today in the scientific journal PLoS One by a group of 14 authors. The joint National Science Foundation (NSF) and...

Genome sequencing helps identify essential protein in disease-carrying parasites Researchers from Boston College have discovered a protein that plays a pivotal role in the progression of the deadly diseases toxoplasmosis and malaria and shown that its function could be genetically blocked in order to halt the progress of the parasite-borne illnesses, the team reports in the current edition of the journal Science. The protein, identified as DOC2.1, plays a similar role in the secretion...
