The clinical manifestations of sick cattle are hypersensitivity to vision, touch, and hearing, vegetative nerve regulation disorders, and ataxia. The typical pathological change is the degeneration of spongy vacuoles in specific areas of gray matter in the brainstem of sick cattle. Scientific investigations and studies have confirmed that the disease originated from scrapie in sheep, and can be transmitted to humans through contaminated food or biological products, causing people to be infected with Variant CJD and die.

[0003] There is no effective treatment and simple early diagnosis method for mad cow disease, so it has become the most threatening anima...
