Outline
The transmission of prions can induce the largely spread of transmissible spongiform encephalopathies, which pose a serious threat to animal and human health. Soil is a natural reservoir for prions. Prions can enter the soil through animal excretion, carcass decomposition, and bind to soil components. The binding of prions to different soil components varies significantly, and their effects are simultaneous and mutual, jointly influencing the spread of prions in the soil. On the one hand, the adsorption of soil particles and humic substances enhances their stability and persistence in the soil, reduces their bioavailability, and thus inhibits the spread of prions. On the other hand, montmorillonite and manganese ions can increase their activity and infectivity to a certain extent, thereby contributing to the spread of prions. The control of prions in the soil can be achieved through biotechnologies such as environmental prevention and control, enzyme treatment and composting technique, based on the improvement of their detection methods. In the future, the research on prions in the soil environment should take more into account the influence of the characteristics of soil compounds and native microorganisms on prions, so as to promote the development of in-situ prion degradation methods to control their spread. This work will provide theoretical support for the development of new technologies for soil prions control.
