black disease
Noun: A specific disease affecting the liver, particularly in sheep and cattle. It is caused by infection with liver flukes (parasitic flatworms) and the toxic effects of their metabolic by-products. The condition is characterized by liver damage and discoloration.
This is a technical veterinary and agricultural term. It is used to describe a specific pathological condition in livestock. * The farmer quarantined the flock after diagnosing a case of black disease. * Control of the snail population is crucial for preventing black disease in this region.
The term is highly specific. In broader contexts, the more general term "infectious necrotic hepatitis" may be used in scientific literature. The name "black disease" refers to the darkened appearance of the damaged liver tissue upon post-mortem examination.
- Infectious necrotic hepatitis: The formal medical/veterinary term for this condition.
- Liver fluke disease: A more general term for conditions caused by and related flukes, which includes black disease.
- Fascioliasis: The disease state resulting from infection with liver flukes ( species).
- Infectious necrotic hepatitis (formal synonym)
This term refers exclusively to a veterinary disease. It is not used in human medicine and should not be confused with other conditions that may have "black" in their name (e.g., Black Death, black lung disease). Its meaning is fixed and technical.
