Table 2 Survival times and attack rates of bank voles after inoculation with brains from P75-7 and P90-4 and comparison with other isolates

From: Further characterisation of transmissible spongiform encephalopathy phenotypes after inoculation of cattle with two temporally separated sources of sheep scrapie from Great Britain

Inoculum Survival time (attack rate) on primary transmission Survival time (attack rate) on second passage Survival time (attack rate) on third passage
P75-7 627 ± 72 (7/12) 18K 144 ± 7 (7/7) 18K 122 ± 5 (10/10)
17K 145 ± 7 (14/14) 17K 111 ± 15 (6/6)
P90-4 382 ± 159 (11/15) 100 ± 5 (8/8) 95 ± 5 (7/7)
CH1641   18K 147 ± 11 (8/8) 18K 139 ± 9 (13/13)
17K 112 ± 8 (10/10) 17K 119 ± 6 (10/10)
SCR6 197 ± 19 (18/18) [12] 98 ± 4 (11/11) [12] 94 ± 5 (11/11)
SS-UK6 175 ± 18 (22/22) [12] 96 ± 4 (11/11) [12] 85 ± 4 (8/8)
  1. Survival times are expressed in days post inoculation with standard error of the mean.
  2. K denotes the molecular masses (in kDa) of the unglycosylated PrPres band determined by WB.
