Fig. 7 — Transmission in mice. The pattern of distribution of disease profiles depending on inocula a after exposure to crude brain, plasma or buffy coat derived from vCJD-infected mice or primates or (PrP^d negative or PrP^d positive) myelopathic primates, or b after exposure to SNC or spleen samples derived from mice exhibiting complete or incomplete vCJD phenotypes (secondary transmission). 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 PrP^d, black), bulbospinal (BS) pattern (protease-resistant PrP^d, white-spotted black), spinal (S) profile (protease-sensitive PrP^d, grey) or cerebral involvement grouping cerebral (C), bulbar (B) profiles and animals with only neuronal lesions (NL) (no detectable PrP^d, white). The fifth category (grey-spotted white) corresponds to the non-vCJD mice (affected mice devoid of PrP^res but not sampled for histology. They might present either a spinal profile or cerebral involvement). Below each circular panel are specified the percentage of transmission and the numbers of aging spinal animals (AS)
