Aujeszkys disease (AD) - Pseudorabies virus (PRV)

For the main information on this disease see chapter 12.

(455) Aujeszky's disease (Fig.10-5) is not normally regarded as a cause of skin changes, but in acute outbreaks small vesicles of approximately 1mm in diameter may be seen on the skin around the nose and the mouth. Similar lesions are occasionally seen in PRRS.
