Pseudorabies Pathology

The nature, cause, origin, and progress of Pseudorabies.


Pseudorabies, also known as Aujeszky’s disease, is caused by an alphaherpesvirus, a member of the family Herpesviridae. The virus infects the central nervous system and other organs, such as the respiratory tract, in virtually all mammals except humans and the tailless apes. The pseudorabies virus (PRV) is not contagious to humans, not even to people working on farms with many PRV-infected animals.

It is associated primarily with pigs, the natural host, which remain latently infected (infected without symptoms) following clinical recovery.

The disease is controlled by containment of infected herds and by the use of vaccines and removal of latently infected animals.
