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...

Twelve (57%) of 21 patients had died of the illness....

U.S. researchers reported on Friday that a rare genetic mutation may underlie some cases of mad cow disease in cattle and its discovery may help shed light on where the epidemic started.They believe BSE may sometimes arise spontaneously in cattle, as the mutation, in an Alabama cow that tested positive in 2006 for bovine spongiform encephalopathy, or BSE, is identical to one that causes a related brain-wasting disease in humans. "Cattle producers must never let down their guard against BSE...

The risk of transmitting bovine spongiform encephalopathy, known as mad cow disease, through blood transfusion is surprisingly high, Scottish researchers said. Bovine spongiform encephalopathy, or BSE, one of a group of rare neurodegenerative disorders called transmissible spongiform encephalopathies, has no reliable non-invasive test for detecting infection before the onset of clinical disease. In addition to BSE, these diseases include scrapie, a closely related disease in sheep, and...

Originally By Steve LeBlanc, Associated Press Public health officials in Massachusetts are investigating whether a patient in a Cape Cod hospital has the human form of mad cow disease. Dr. Alfred DeMaria, the state's director of communicable disease control, confirmed Sunday to The Associated Press that tests are being done to see if the patient has Creutzfeldt-Jakob disease and whether it's the variant attributed to mad cow. There have only been three cases of the human form of mad cow...

NEW YORK (Reuters Health) - In patients with cirrhosis of the liver due to infection with hepatitis C virus (HCV), the presence of diabetes is associated with earlier onset and greater severity of liver or "hepatic" encephalopathy, according to results of a prospective study. Hepatic encephalopathy is a complication of cirrhosis of the liver. Toxic substances like ammonia that accumulate in the blood and impair the function of brain cells are believed to be contributing factors. Dr....

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Tests in hamsters suggest it may be possible to develop a blood test for mad cow and related diseases in both humans and animals before they develop symptoms, researchers reported on Thursday. The study, published in the journal Science, also suggests that the damaged brain cells may "leak" the infectious prions that cause the diseases, offering a chance to detect the disease in blood. Such a test would allow...

By Patricia Reaney LONDON (Reuters) - People could be infected with the human form of mad cow disease for more than 50 years without developing the illness, which means the size of a potential epidemic may be underestimated, UK scientists said on Friday. So far about 160 people have been diagnosed with variant Creutzfeldt-Jakob disease (vCJD). Cases of the fatal disease have also been reported in France, Italy, Ireland, the Netherlands, Canada, Japan and the United States. Estimates...

VANCOUVER, British Columbia (Reuters) - Tests have confirmed that a six-year-old dairy cow in the Canadian province of British Columbia suffered from mad cow disease, the government said on Sunday. The pure-bred Holstein is Canada's fifth native-born case of the brain-wasting bovine spongiform encephalopathy disease, but the animal did not enter the human food chain, Canada's Food Inspection Agency said. Officials had announced the suspected case last week.

The scientific magazine Brain Research has recently published the results of research work by scientists from the University of Navarra. The work describes the presence and location of the cellular prion protein (PrPC) in the brain of the rat and characterises the neurones expressed therein, above all within the cerebral cortex of this rodent. The authors are Jos© Luis Velayos and Francisco Jos© Moleres, research scientists at the Department of Anatomy at the University of Navarra....
