Spread of Scrapie from Inoculated to Uninoculated Mice

Abstract

Summary

Scrapie occured in 7 of 200 uninoculated control mice housed in the same room with, but caged separately from, successive groups of scrapie inoculated mice. Clinical evidence of the disease appeared in controls as early as 16 months and as late as 22 months after initial exposure to scrapie inoculated mice.
