Development may help shed light on disease in animals and protect human populationsCurrent tests to identify specific strains of infectious prions, which cause a range of transmissible diseases (such as mad cow) in animals and humans, can take anywhere from six months to a year to yield results "“ a time-lag that may put human populations at risk.Now, a group of scientists from The Scripps Research Institute's Florida campus have developed a new method that cuts this critical time lag...

A blood test has been developed by Canadian researchers that can diagnose fatal chronic wasting disease in elk, and may provide an inexpensive approach to screening for mad cow disease. According to the researchers, the test looks for damaged cells in the blood, and may also provide a way to diagnose Creutzfeldt-Jakob disease in humans. The report appears in the journal Nucleic Acids Research. "We can now take a blood sample from a live animal and look at the DNA patterns in the blood and...

In the rogues' gallery of microscopic infectious agents, the prion is the toughest hombre in town. Warped pathogens that lack both DNA and RNA, prions are believed to cause such fatal brain ailments as chronic wasting disease (CWD) in deer and moose, mad cow disease in cattle, scrapie in sheep and Creutzfeldt-Jakob disease in humans. In addition to being perhaps the weirdest infectious agent know to science, the prion is also the most durable. It resists almost every method of destruction...

A worldwide group of scientists has created an infectious prion disease in a mouse model, in a step that may help unravel the mystery of this progressive disease that affects the nervous system in humans and animals. The research team, including Christina J. Sigurdson, D.V.M., Ph.D., assistant professor of pathology at the University of California, San Diego School of Medicine, also discovered that changing the structure of the prion protein by altering just two nucleic acids leads to a fatal...

By Maggie Fox, Health and Science Correspondent WASHINGTON -- The muscles of deer affected by a mad cow-like disease carry the infectious prions that spread the illness, meaning that venison could potentially spread the agent to humans, researchers reported on Thursday. They said leg muscle tissue taken from mule deer with chronic wasting disease (CWD) infected specially bred mice when they were injected with the tissue. While stressing that was a long way from showing venison was infectious,...

NEW YORK (Reuters Health) - Findings from an animal study suggest that disease-cause prions can be spread via infected skeletal muscle from deer with chronic wasting disease (CWD) -- a wildlife illness related to mad cow disease. Whether CWD can be passed to humans is still unclear, but the present findings suggest that if this does occur, simply handling the meat of infected dear could pose a risk, senior author Dr. Glenn C. Telling, from the University of Kentucky in Lexington, and...

MADISON -- White-tailed deer, it seems, are homebodies. That is the upshot of an intensive study of the traveling behaviors of 173 radio-collared white-tailed deer in south central Wisconsin. The new results, which surprised researchers by revealing how little deer move about the landscape, are important because they may help researchers and wildlife managers better understand how chronic wasting disease (CWD) spreads. "They are using small home ranges and not traveling long distances,"...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - The agent that causes mad cow disease, scrapie and chronic wasting disease in deer and elk may sometimes be spread through urine, Swiss researchers reported on Thursday. They found that, under certain conditions in mice, the deformed brain proteins known as prions that transmit the disease could be found in urine. "We tested whether chronic inflammatory kidney disorders would trigger excretion of prion...
