Pseudorabies, also called Aujesky's Disease, Mad Itch, and Infectious Bulbar Paralysis, is a viral disease which primarily affects pigs. It occurs in a wide variety of domestic and wild animals and birds, but not in apes, reptiles, or insects. The natural viral reservoir is swine, in which it produces high mortality in suckling pigs, relatively low mortality in older pigs, and may produce carriers showing few or no symptoms.
