Table 4 Mouse bioassay results for white-tailed deer fetal tissues from CWD-positive dams. Cervidized (TgCerPrP−E2265037+/−) mice were intraperitoneally (IP) inoculated with fetal brain (fetuses 5–12 A and 7–6 A) or fetal thymus (6-1B) samples. Terminal mouse brain and spleen tissues were tested in conventional RT-QuIC for amyloid seeding activity. Mock inoculated mice remained free of clinical signs throughout, and tested CWD-negative upon terminal collections in all cohorts. DPI = days post inoculation. # pos/total mice = number CWD-positive/total number inoculated.
