Turns model parasite into genetic workhorse-In a genetic leap that could help fast track vaccine and drug development to prevent or tame serious global diseases, DMS researchers have discovered how to destroy a key DNA pathway in a wily and widespread human parasite. The feat surmounts a major hurdle for targeting genes in Toxoplasma gondii, an infection model whose close relatives are responsible for diseases that include malaria and severe diarrhea."This opens a wide window on a complex...

Researchers at the University of Pennsylvania have discovered that parasites hijack host-cell proteins to ensure their survival and proliferation, suggesting new ways to control the diseases they cause. The study, appearing this week online in Science, was led by Doron Greenbaum, PhD, Assistant Professor of Pharmacology in the Penn School of Medicine."Researchers can now develop ways to kill parasites by placing roadblocks in the path they use to destroy their victims," says Greenbaum. The...

Scientists in the UK have reported the first evidence that links schizophrenia to toxoplasma parasites. People who become infected by toxoplasma may develop a minor illness called toxoplasmosis, which can become serious if it is passed from pregnant mother to child. Previous studies have suggested that toxoplasmosis can indirectly cause schizophrenia because of dopamine-blocking treatments like haloperidol. However, Dr. Glenn A. McConkey at the University of Leeds, told Reuters Health that...

CHULA VISTA, Calif., March 17 /PRNewswire/ -- A study by the Stanley Medical Research Institute and Johns Hopkins University Medical Center links Toxoplasma, a cat-borne parasite, to neurotic behavior in infected men and women. Between 25 and 50 percent of the world's human population - and 30 percent of the U.S. population - may be infected. Toxoplasma eggs are shed in an infected cat's feces and then passed to humans when changing cat litter, gardening and petting. In 2000, studies...

British scientists say toxoplasmosis parasite may trigger the development of schizophrenia and bipolar disorders. The team from the University of Leeds shows the parasite may play a role in the development of the disorders by affecting the production of dopamine -- the chemical that relays messages in the brain controlling aspects of movement, cognition and behavior. Toxoplasmosis, which is transmitted through cat feces -- and can be found on unwashed vegetables as well as raw or undercooked...

Scientists have discovered how the toxoplasmosis parasite may trigger the development of schizophrenia and other bipolar disorders. The team from the University of Leeds' Faculty of Biological Sciences (UK) has shown that the parasite may play a role in the development of these disorders by affecting the production of dopamine - the chemical that relays messages in the brain controlling aspects of movement, cognition and behavior. Toxoplasmosis, which is transmitted via cat feces (found on...

 For the first time, a team of researchers at the University of Pennsylvania School of Veterinary Medicine have imaged in real time the body's immune response to a parasitic infection in the brain.The complete findings, published in the current issue of the journal Immunity, provide unexpected insights into how immune cells are regulated in the brain and have implications for treatment of any inflammatory condition that affects the brain.Toxoplasma, a common parasite of humans, is found...

The U.S. Geological Survey says central California sea otters risk higher exposure to disease-causing parasites due to the food they eat and where they feed. Researchers said sea otters that eat small marine snails are at a higher risk of exposure to Toxoplasma gondii, a potentially deadly protozoal pathogen, than animals that feed exclusively on other prey. Sea otters living along the coast near San Simeon and Cambria are more at risk than sea otters outside that area. Recovery of the sea...

Sea otters living along the central California coast risk higher exposure to disease-causing parasites as a consequence of the food they eat and where they feed. Sea otters that eat small marine snails are at a higher risk of exposure to Toxoplasma gondii, a potentially deadly protozoal pathogen, than animals that feed exclusively on other prey, while sea otters living along the coast near San Simeon and Cambria are more at risk than sea otters that live outside this area. Similarly, sea...

By Valenzuela, Stella Cortie, Michael Gold nanoparticles can target and kill the parasite Toxoplasma gondii, opening the way for a new treatment for parasitic infections in humans. Over the ages, people worldwide have revered gold as a precious metal, with its uses being many and varied. In cultures where the Sun was worshiped as a deity, gold was viewed as its representative form on Earth. It has also commonly been used for decorative purposes in art, food and jewellery. Other uses include...
