Histologic analysis of brain tissue from K222-Tg516 homozygous mice inoculated with classical scrapie in study of propagation of classical scrapie prions. Comparative analysis shows the vacuolar lesion profile in homozygous K222-Tg516 mice inoculated with different scrapie isolates compared with noninoculated mice. G, gray matter; W, white matter.
