Scientists Closer to Unfolding Mysteries of Prion Formation in Mad Cow Disease

Short elements within a prion protein's sequence can cause it to activate and even cross the species barrier to spread neurodegenerative disorders such as Creutzfeldt-Jakob disease to humans

Prions, the maddening, infectious proteins, and the diseases they trigger, such as the fatal neurodegenerative disorder in humans, Creutzfeldt-Jakob disease—as well as its bovine counterpart, mad cow disease—have baffled scientists for decades. Although researchers know what they are (abnormally folded proteins) and the illnesses that they cause, how they form and multiply has remained elusive.

GeneThera in Preliminary Talks for Mad Cow Testing

WHEAT RIDGE, CO -- (MARKET WIRE) -- April 16, 2007 -- GeneThera, Inc. (OTCBB: GTHA) announced today it has begun preliminary talks with ranchers to test their cattle for the Mad Cow disease.

Commenting on the talks Dr. Tony Milici stated, "These preliminary talks are an important first step to establish our commercial platform once private companies will be allowed to test for Mad Cow disease in the US. We believe that allowing private companies to test for Mad Cow will have a very positive impact on the US beef industry domestically and internationally."

The USDA has previously not allowed private companies to test their cattle for Mad Cow. However, a federal judge ruled that the federal government must allow meatpackers to test their animals for Mad Cow Disease. The judge put his order on hold until the government can appeal. If the government does not appeal by June 1, 2007, he stated the ruling would take effect.

Toward Safer Disposal Of Animals Infected With Mad Cow And Other Prion Diseases

Science Daily — Burying prion-infected carcasses of cattle, deer and other animals in lime may actually enhance the spread of those infectious proteins through soil, a new study suggests. Placing quicklime on carcasses once was thought to be the best way to foster quick decay of bodies and to prevent the spread of disease.

The study is scheduled for the April 15 issue of ACS’ Environmental Science & Technology, a semi-monthly journal.

In the study, Joel A. Pedersen and colleagues from the University of Wisconsin cite the need for safe methods of disposing of prion-infected carcasses, noting that prions can resist harsh conditions such as strong disinfectants and dry-heat temperatures of 1,100°F that destroy other disease-causing agents and that prions can remain infectious in the soil for at least three years. Pedersen and colleagues investigated the effect of different conditions (pH, salinity) on the adsorption, or attachment, of prions to sand particles.
