The following changes were made: (i) the following sentence was added to p. 22: “However, Tg mice expressing ovine PrP challenged with CWD have resulted in highly efficient, life-long asymptomatic replication of these prions in the spleen tissue, with brain involvement at late stage (Béringue et al., 2012)”; (ii) the reference to Béringue et al., 2012 was added to the Reference list and (iii) wapiti was added to the top of p.21. These changes do not materially affect the contents or outcome of this scientific output. To avoid confusion, the older version has been removed from the EFSA Journal, but is available on request, as is a version showing all the changes made.
