Your Elder is suffering from a form of spongiform encephalopathy.

你长老患是一种海绵状。

Your neurology department loaned me a culture of prions for my research on bovine spongiform encephalopathy.

你们神经科学部门借了朊毒培养箱来协助牛海绵状。

In particular, Prion disease creates holes in the brain, giving it a spongiform appearance and ultimately causing death.

特别是，朊毒会在大中形成一个个洞，使其看起来像海绵一样，最终导致死亡。
