scrapie
LowTechnical/Scientific
Definition
Meaning
A fatal, degenerative prion disease affecting the central nervous system of sheep and goats.
Used metaphorically in rare instances to describe something that is slowly, insidiously deteriorating or causing a progressive decline, often in an organizational or systemic context.
Linguistics
Semantic Notes
The term is a mass noun (uncountable). It refers specifically to the disease state, not an individual instance. It is a transmissible spongiform encephalopathy (TSE), similar to BSE (mad cow disease) in cattle.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. The disease is known by the same term in both veterinary and agricultural contexts globally.
Connotations
Connotes a serious agricultural/animal health concern. It may evoke imagery of rural farming, animal welfare, and biosecurity.
Frequency
Slightly higher frequency in UK English due to historical prevalence and research focus on prion diseases in the UK, but remains a low-frequency technical term.

Business
Used in the livestock trade, insurance, and export/import regulations concerning animal health.
Academic
Central to veterinary science, prion biology, epidemiology, and agricultural policy research.

FAQ
Frequently Asked Questions
No, there is no scientific evidence that scrapie is transmissible to humans under normal circumstances.
No, there is currently no cure or vaccine. Management focuses on surveillance, culling infected animals, and breeding for genetic resistance.
Definitive diagnosis requires post-mortem examination of brain tissue to detect the characteristic spongiform changes and prion proteins.
It naturally affects sheep and goats. It is not a disease of cattle (that's BSE) or humans.
