Mice Aren't Scaredy-Cats When Infected By Toxoplasma
2013-09-19 13:05:53

Brett Smith for redOrbit.com - Your Universe Online Known to cause spontaneous abortions in pregnant women or death in immune-compromised patients, the parasite Toxoplasma gondii has an even stranger effect in mice – it takes away their fear of cats. The fearless mice are a boon to both cats, which get an easy meal, and the parasite, which gets access to the cat's intestinal track – the only place the parasite can sexually reproduce. According to a new University of California,...

A benign crystal protein, produced naturally by bacteria and used as an organic pesticide, could be a safe, inexpensive treatment for parasitic worms in humans and provide effective relief to over a billion people around the world. Researchers from the University of California, San Diego, La Jolla, CA, report on this potentially promising solution in a study published ahead of print in the journal Applied and Environmental Microbiology. Hookworms, and other intestinal parasites known as...

A study conducted by Dr. James Diaz, Professor of Public Health and Preventive Medicine and Program Director of the Environmental/Occupational Health Sciences Program at the LSU Health Sciences Center New Orleans School of Public Health, analyzed cases of a parasitic lung infection and found new modes of transmission and associated behaviors, identifying new groups of people at risk. Dr. Diaz hopes to raise the index of suspicion among medical professionals so non-traditional patients and...

Chronic Disease In Toxoplasma Infections Controlled By Plant Proteins

University of South Florida University of South Florida-led research sheds light on malaria-related parasite's transition from acute to chronic stage A new discovery about the malaria-related parasite Toxoplasma gondii -- which can threaten babies, AIDS patients, the elderly and others with weakened immune function -- may help solve the mystery of how this single-celled parasite establishes life-long infections in people. The study, led by a University of South Florida research team,...

Screening method created to expedite the development of new drugs in the fight against tropical diseases such as malaria and African sleeping sickness A novel tool exploits baker's yeast to expedite the development of new drugs to fight multiple tropical diseases, including malaria, schistosomiasis, and African sleeping sickness. The unique screening method uses yeasts which have been genetically engineered to express parasite and human proteins to identify chemical compounds that target...

Amphibian Biodiversity Makes Entire Ecosystem Healthier
2013-02-14 12:24:37

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Colorado, Boulder shows that the richer the biodiversity of amphibian species living in a pond, the more protection that ecosystem has against parasitic infections. The finding of the study support the broader theory that greater biodiversity in large-scale ecosystems such as forests or grasslands may also provide greater protection against diseases, including those that attack humans. A larger...

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...

Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study. According to CU-Boulder Assistant Professor Pieter Johnson, scientists are concerned about how changes in biodiversity affect the risk of infectious diseases in humans and wildlife. Charting the relationships between parasites and amphibians is...

How parasites use different life-history strategies to beat our immune systems may also provide insight into the control of diseases, such as elephantiasis and river blindness, which afflict some of the world's poorest communities in tropical South-East Asia, Africa and Central America. The research is due to be published next week in the online, open-access journal PLoS Biology. The study, led by Dr Simon Babayan of the University of Edinburgh, showed using a mouse model of parasite...


Word of the Day
out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
