“…Relevant studies have shown that temperature can induce prion to fold, and prion (PrP C ) folds into a toxic scrapie form (PrP SC ) [54]. In environmental transmission, the bioavailability of prion in soil may also be affected by temperature [29]. Furthermore, the climatic conditions with more precipitation are unsuitable for prion occurrence [55].…”

“…Recently, the number of live sheep worldwide has been concentrated in Asia [28], and the distribution of sheep and goats has become a nonnegligible risk factor for the spread of scrapie. Further exploration of the range of factors influencing the persistent presence of prions in the environment will facilitate the study of the mechanisms of the occurrence and transmission of scrapie [29]. In fact, most pathogenic microorganisms can be transmitted through environmental pathways, and bioclimatic variables are an important factor [30].…”

“…Scrapie prions have been observed to persist in soils for years. For BSE prions, Maddison et al 146,147) showed highly efficient binding of bovine BSE PrP Sc to different types of soil within 24 h. Clay-rich soils induced N-terminal truncation of the PrP Sc , but sand-rich soils yielded full length PrP Sc species. The recovery and persistence of PrP Sc in sandy loam soil decreased during the 18-months incubation period in a temperature-dependent manner, but average percent of recovery at day 566 remained over 10% of that at day 1-4 at any temperatures.…”

“…The binding and survival of TSE agents is influenced by soil composition and the TSE strain, with ovine scrapie being more persistent in some soil types than cattle BSE [ 17 , 18 ], and oral infection may be promoted by binding of TSE agents to soil components [ 14 , 19 , 20 ]. There is also evidence that PrP Sc can be taken up by plants from experimentally infected soil [ 21 ].…”
