Mad Cow Disease

Fear of mad cow disease, a lethal illness transmitted from infected beef to humans, has spread from Europe to the United States and around the world. Originally published to much acclaim in France, this scientific thriller, available in English for the first time and updated with a new chapter on developments in 2001, tells of the hunt for the cause of an enigmatic class of fatal brain infections, of which mad cow disease is the latest incarnation. In gripping, nontechnical prose, Maxime Schwartz details the deadly manifestations of these diseases throughout history, describes the major players and events that led to discoveries about their true nature, and outlines our current state of knowledge. The book concludes by addressing the question we all want answered: should we be afraid? The story begins in the eighteenth century with the identification of a mysterious illness called scrapie that was killing British sheep. It was not until the 1960s that scientists understood that several animal and human diseases, including scrapie, were identical, and together identified them as transmissible spongiform encephalopathy (TSE). The various guises assumed throughout history by TSE include an illness called kuru in a cannibalistic tribe in Papua New Guinea, an infectious disease that killed a group of children who had been treated for growth hormone deficiencies, and mad cow disease. Revealing the fascinating process of scientific discovery that led to our knowledge of TSE, Schwartz relates pivotal events in the history of biology, including the Pasteurian revolution, the birth of genetics, the emergence of molecular biology, and the latest developments in biotechnology. He also explainsthe Nobel Prize-winning prion hypothesis, which has rewritten the rules of biological heredity and is a key link between the distinctive diseases of TSE.

In 1996, British doctors were horrified to discover that mad cow disease (BSE), an affliction that had been plaguing British cattle for ten years, had jumped the species barrier and was appearing in humans as variant Creutzfeldt-Jakob disease (vCJD). Not unlike the mad cows, victims of vCJD suffer from a degenerative neurological disease that peppers the brain with microscopic holes, causing dementia, loss of motor control, and certain death. What alarms researchers and public health officials worldwide is that the incubation period for vCJD may be as long as 10 or even 15 years, and during this period those infected are symptom-free. And because the disease is so far undetectable except by autopsy, there is no way of knowing with certainty how many people have already been infected. In fact, even travelers who spent time in the U.K. from the early 1980s through the mid-1990s are still considered to be at some risk. What's more, although the U.S. has not detected any mad cows within its borders, there are plenty of "mad deer" running free in several states, and the disease afflicting them is a BSE-type neurological disorder. Called chronic wasting disease (CWD), the illness in these deer has yet to be linked with any human deaths. But given BSE's ability to jump species, there are no guarantees. In The Pathological Protein, Philip Yam describes how, in this atmosphere of uncertainty, scientists have discovered that the agent of disease in vCJD and a host of other devastating neurological disorders is a bizarre, misshapen version of a protein called a prion. Once introduced into the human neurological system, malformed prions recruit the body's own normal prion proteins, giving them thesame pathological ability to destroy brain tissue. Unlike the better-known pathogens that afflict humans--bacteria, viruses, and parasites--prions have so far proved resistant to drug therapies and even standard sterilization.

Prion - ... Though the exact mechanisms of their actions and reproduction are unknown, it is now commonly accepted that prions are responsible for a number of previously known but little-understood diseases generally classified under transmissible spongiform encephalopathy diseases (TSEs), including scrapie (a disease of sheep), kuru (found in members of the formerly cannibalistic Foré tribe in Papua New Guinea), Creutzfeldt-Jakob disease (CJD), Chronic Wasting Disease, Fatal Familial Insomnia (FFI), Gerstmann-Sträussler-Scheinker syndrome (GSS), and bovine spongiform encephalopathy (BSE or mad cow disease) .

Bovine spongiform encephalopathy - Bovine spongiform encephalopathy (BSE), commonly known as mad cow disease, is a fatal, neurodegenerative disease of cattle, which infects by a mechanism that shocked biologists on its discovery in late 20th century. The disease appears transmissible to humans.
