Latest Prion Research and Review in PLoS Pathogens
Freely Accessible Online

April 21, 2006

Dear Colleague,

We'd like to draw your attention to a research paper published online in PLoS Pathogens, entitled Prions Adhere to Soil Minerals and Remain Infectious by Joel Pederson and colleagues (University of Wisconsin-Madison).

Please feel free to read, share, print, and use this article anyway you wish, all at no charge—thanks to open access publishing.

The Study

Pedersen and colleagues examined the potential for soil to serve as a prion disease reservoir by studying the interaction of the disease-associated prion protein (PrPSc) with common soil minerals. Their results suggest that PrPSc released into soil may be preserved in a bioavailable form, perpetuating prion disease outbreaks and exposing other species to the infectious agent.


In a related Review article entitled The Expanding Universe of Prion Diseases, Joel C. Watts, Aru Balachandran, and David Westaway (University of Toronto and the Canadian Food Inspection Agency) chronicle the emergence of four novel prion diseases in the past decade and explore the possibility that the appearance of new outbreaks and forms of disease may be an inherent feature of host-encoded pathogens.

PLoS Pathogens

From molecules to physiology, PLoS Pathogens publishes important new ideas on bacteria, fungi, parasites, prions, and viruses that contribute to our understanding of the biology of pathogens and pathogen—host interactions.
