^★

Mean incubation period (IP) of scrapie sick animals ± SD.

^†

Mann–Whitney test comparing incubation period for each inoculum against controls within each strain.

^‡

The large SD in this group was attributable to two animals with incubation times of 214 and 288 days; excluding these animals, the incubation period of the remaining hamsters in this group was 110 ± 5 days.
