Big oof leading with the microorganism thing. Prions are not microorganisms at all, nothing's alive in there.

You're at the absolute baseline of information here it seems, so to get the information you're looking for just get on YouTube, type "What is a Prion", click the first video you see, and get learned.

Just saw you're a Polska, understand the accidental use of an inaccurate word now. My advice still stands, though. Check YouTube.
