Subject: Prion

It is suspected that the cause of bovine sponiform encephalopathy is prion, and people are afraid that human may get a similar disease if they ingest affected beef.

But since prion is a protein, wouldn't it be digested by enzymes if ingested, or if it is undigestable, how can it be absorbed in human gut and be assimilated into the body, especially the brain?

If it cannot be abosorbed, why are people suspecting infected beef as a cause of disease?
