Bovine Spongiform Encephalopathy Bse Or Mad Cow Disease

Through mid-May 2007, the United States had confirmed three cases of bovine spongiform encephalopathy (BSE, or "mad cow disease"): the first in December 2003 in a Canadian-born cow found in Washington state, the second in June 2005 in cow in Texas, and the third in March 2006 in a cow in Alabama. Shortly after the first case, U.S. Department of Agriculture (USDA) and other officials announced measures to improve existing safeguards against the introduction and spread of BSE. Previously, the major safeguards were: (1) USDA restrictions on imports of ruminants and their products from countries with BSE; (2) a ban on feeding most mammalian proteins to cattle and other ruminants, issued by the Food and Drug Administration (FDA); and (3) a targeted domestic surveillance program by USDA's Animal and Plant Health Inspection Service (APHIS), the agency responsible for animal health monitoring and disease control.

The alarm sounded by Canada's confirmed case of bovine spongiform encephalopathy (BSE) has reaffirmed the exigency of establishing improved safeguards and more aggressive surveillance protocols in North America and around the world. Research converging on the probable causative agent--prion proteins--calls for intensive assessment of the headway gained in tracing prions, testing for transmissible neurodegenerative diseases, and developing methods for cornering the epidemic. With an illustrious panel of 36 international contributors, this timely book marshals techniques for prion protein assay and diagnosis of transmissible spongiform encephalopathies (TSEs).

This book presents important analyses of current issues in BSE (bovine spongiform encephalopathy or "mad cow disease") as a fatal neurological disease of cattle, believed to be transmitted mainly by feeding infected cattle parts back to cattle. More than 187,000 cases have been reported world-wide, 183,000 of them in the United Kingdom (UK) where BSE was first identified in 1986. The annual number of new cases has declined steeply since 1992. Humans who eat contaminated beef are believed susceptible to a rare but fatal brain wasting disease, variant Creutzfeldt-Jakob Disease (vCJD). About 160 people have been diagnosed with vCJD since 1986, most in the UK and none linked to any Canadian or U.S. meat consumption.

"How the Cows Turned Mad tells the story of a disease that continues to elude on many levels. Yet science has come far in understanding its origins, incubation, and transmission. This book is a case history that illuminates the remarkable progression of science."--BOOK JACKET.

Bovine spongiform encephalopathy (BSE) has become the most publicly recognizable example of a group of fatal neurodegenerative diseases caused by proteinaceous infectious particles called prions. The contributors to this volume, all internationally recognized experts in their fields, provide an introduction to prion biology, followed by reviews of the latest information on BSE, vCJD, and chronic wasting disease, an animal prion disease that has recently emerged in North America.

Human Prion Diseases, Volume 153 is designed to update the reader on the latest advances and clinical aspects of prion diseases. The book is organized into five sections, including the pathophysiology of prions and a description of animal and human diseases. This is followed by detailed reports on recent advances in diagnosis strategies for the development of novel anti-prion molecules and possible designs of clinical trials in such a rare disease. An introductory chapter gives an extensive historical background of prion research, with a final chapter highlighting recent progress, and more importantly, unsolved problems. Offers an authoritative overview of prion diseases in humans, detailing the pathogenesis of the disease, clinical investigations, and the diagnosis of both the genetic and acquired forms Provides clarity and context by presenting prion diseases in relation to other neurodegenerative diseases in humans Emphasizes the unique properties of prion diseases and consequent problems they can cause, both clinically and in public health terms
