a The pattern of distribution of disease profiles in mice according to the kind of inocula (brain, soluble infectivity or blood products). For each inoculum, the pattern of disease profiles observed in affected mice (numbers at the centre of each circle) is depicted in five categories grouped according to their status towards abnormal PrP: classical vCJD pattern (protease-resistant PrPd, black), bulbospinal (BS) pattern (protease-resistant PrPd, white-spotted black), spinal (S) profile (protease-sensitive PrPd, grey) or cerebral involvement grouping cerebral (C), bulbar (B) profiles and animals with only neuronal lesions (NL) (no detectable PrPd, white). The fifth category (grey-spotted white) corresponds to the non-vCJD mice (affected mice devoid of PrPres but not sampled for histology. They might present either spinal profile or cerebral involvement). Below each circular panel are specified the percentage of transmission and the numbers of aging spinal animals (AS). b Two different putative pathophysiological pathways may occur depending on the aggregated or soluble nature of the initial infectivity
