Prion diseases: A challenge to animal health.

Prion diseases are known as transmissible spongiform encephalopathies (TSE), a group of rare, rapidly progressive, and fatal neurologic diseases. The agents responsible for human and animal prion diseases are abnormal proteins (prion or proteinaceous infectious particle) that can trigger chain reactions causing normal proteins in the brain to change to the abnormal protein. These abnormal proteins are resistant to enzymatic breakdown, and they accumulate in the brain, leading to damage. All have long incubation periods followed by chronic neurological disease and fatal outcomes, have similar pathology limited to the CNS include convulsions, dementia, ataxia (balance and coordination dysfunction), and behavioral changes, and are experimentally transmissible to some other species.

BSE safety standards: An evaluation of public health policies of Japan, Europe, and USA

Since the advent of bovine spongiform encephalopathy (BSE) in the United Kingdom in 1986, new BSE cases have recently become rare. However, in Japan and the United States, positive cases have started to be seen recently. The rise in BSE cases paved the way for the human form of this disease, the variant Creutzfeldt-Jakob disease (vCJD). The observed trends in the UK may be attributed to effective implementation of public health policies coupled with increased vigilance through advancement in science and technology, or they may well be a reflection of the natural disease progression. We aim to discuss the BSE chronology of events, and compare examination methods, costs and cost-efficiency, management, and public policies of Japan, Europe, and the USA.
