Prions are proteins that act as an infectious agent. They cause a variety of diseases, including "Mad cow" disease. Prions cannot produce more prions on their own, but cause the host organism to replicate more prions. Most scientists do not consider prions to be alive. A valid reason for accepting that prions are nonliving things is that
