title: Immunoperoxidase study of Aujeszky's disease in pigs.
abstract: Viral antigen was detected by an immunoperoxidase technique in histological sections from pigs with Aujeszky's disease. The antigen was found mainly in association with focal necrosis in the cerebellum, tonsils, oral and nasal mucosa, salivary glands, lungs, liver, kidneys, pancreas, spleen and adrenal glands. Cells at the margin of the necrotic foci especially were strongly positive. Viral antigen was also demonstrated in the cerebral cortex and in the brain stem. Two types of intranuclear inclusion bodies were found to contain viral antigen and one type also contained viral nucleic acids. Inflammatory cells usually contained no viral antigen. The possible significance of some of these infected tissues in the excretion of the virus is discussed.
