摘要: Abstract We have studied clinically nine dogs, and pathologically five with coonhound paralysis. shown that the disease is an acute polyradiculoneuritis. The typical clinical picture ascending flaccid paralysis often facial diplegia. Pathologically, characterized by inflammation segmental demyelination of ventral roots spinal nerves. bite a raccoon has invariably preceded illness interval between 7 14 days. Coonhound been compared in detail to Landry-Guillain-Barre syndrome man, found be nearly identical pathologically. This great similarity strongly suggests pathogenesis common both entities. viral infections so precede syndrome. may looked upon as antigenic stimulus triggering immunological disturbances damage Schwann cells. hypothesis line prevalent theory role
