Mareks disease

a lymphoproliferative disease of fowl caused by a herpes virus. Lymphoid cell infiltrations are most common in the peripheral nerves and gonads, but widespread infiltrations may also be found in any of the visceral organs, skin, muscle, and the iris of the eye. The location of the lesions dictates the clinical signs, such as paralysis, general depression, and blindness.
