The present work reports cerebellar degeneration in cattle associated with the ingestion of Solanum subinerme in northern Brazil. The main clinical signs were periodic crises with loss of balance, falls, opisthotonus, and nystagmus. The histological lesions consisted of diffuse vacuolation of the perikaryon of the Purkinje neurons, followed by the loss of these cells and their substitution by Bergman glia. It is concluded that S. subinerme is another species of Solanum that causes cerebellar degeneration in cattle.
