    Christopher J Johnson
    Prion Research Laboratory, United States Geological Survey National Wildlife Health Center, Madison, Wisconsin, United States of America
    PLoS ONE 6:e19836. 2011
    ..Further work to clone and characterize the protease, assess its effect on TSE infectivity and determine which organism or organisms present in lichens produce or influence the protease activity is warranted...

    Christopher J Johnson
    Prion Research Laboratory, USGS National Wildlife Health Center, Madison, Wisconsin, USA
    J Toxicol Environ Health A 74:161-6. 2011
    ..Our data suggest that in feed or other prion-contaminated substances consumed by animals or, potentially, humans, the addition of MBM or the presence of microparticles could heighten risks of prion disease acquisition...

    PLoS Pathog 2:e32. 2006
    ..Results from our study suggest that PrP(Sc) released into soil environments may be preserved in a bioavailable form, perpetuating prion disease epizootics and exposing other species to the infectious agent...
