Tracking down the cause of mad cow disease
This release is available in German .
The cause of diseases such as BSE in cattle and CreutzfeldJakob disease in humans is a prion protein. This protein attaches to cell membranes by way of an anchor made of sugar and lipid components (a glycosylphosphatidylinositol, GPI) anchor. The ...
K-State professor's USDA research shows mad cow disease also caused by genetic mutation
MANHATTAN, KAN. -- New findings about the causes of mad cow

"We now know it's also in the genes of cattle," said Juergen A. Richt, Regents Distinguished Professor of Diagnostic Medicine and Pathobiology at Kansas State University's College of Veter...
Federal testing for mad cow disease a failure, law review editor says

Successful cell engineering may lead to mad cow prevention, say researchers
