  1. a Cattle with BSE confirmed by postmortem tests.
  2. b BSE field suspects or cattle inoculated with tissue/body fluids from naturally infected BSE cases or from BSE/scrapie-challenged animals, which were not confirmed as BSE cases by postmortem tests.
  3. c Cattle inoculated with saline solution or BSE/scrapie-free tissue or not challenged.
  4. 1 Cattle intracerebrally inoculated with various tissues collected from cattle orally dosed with classical BSE brainstem homogenate and saline-inoculated controls [45, 46].
  5. 2 Cattle orally dosed with 1 g or 100 g classical BSE brainstem homogenate and culled at various times post challenge and undosed controls [1].
  6. 3 Cattle orally dosed with 1 g-1 mg classical BSE brainstem homogenate and undosed controls [7].
  7. 4 Cattle orally dosed with 100 g classical BSE brainstem homogenate and undosed controls as well as controls orally dosed with 100 g BSE-free brainstem homogenate sourced from New Zealand.
  8. 5 Cattle intracerebrally inoculated with scrapie brain homogenate, saline-inoculated controls and controls inoculated with scrapie-free brain [6] as well as cattle orally inoculated with 100 g scrapie brain homogenate and undosed controls.
  9. 6 Cattle intracerebrally inoculated with atypical BSE brain homogenate (L-type or H-type BSE) as well as unchallenged controls.
  10. 7 BSE suspects reported by the farmer and healthy controls purchased from farms [14].
