Figure 3

A total of 260 French field-positive isolates were analyzed with the automated ELISA typing test. Each series of 29 samples was analyzed together with 3 internal controls (classic scrapie, intermediate scrapie, experimental ovine bovine spongiform encephalopathy [BSE]). The ratio obtained for each sample was normalized by dividing by the experimental ovine BSE in the same series. Open bars represent the atypical scrapie cases. Natural goat BSE isolate (Ch636) is indicated.
