PrPd immunolabelling in the solitary tract nucleus of two orally infected BSE cases. A, B: Solitary tract nucleus of two BSE cases orally challenged with 100 g (steer CM873) and 10 mg (steer CM923) respectively of BSE brainstem homogenate and culled one day after the last ECG recording. PrPd immunolabelling with antibody R145. Neuropil PrPd immunolabelling intensity is weaker in A (score 2, CM923, heart rate 57 beats per minute) compared to B (score 4, CM873, heart rate 108 beats per minute).
