Prions (PrP Sc) are shed from sheep and goats in birth fluids, feces, and other excrement. The concentration of the prions is uncertain, but is not directly proportional to infectivity. Sheep ingest a considerable amount of soil, so soil represents a plausible environmental reservoir of scrapie prions, which can persist in the environment for ...
