Oculoglandular Syndrome Caused by Yersinia pseudotuberculosis in a Dairy Goat

An outbreak of ocular disease in a herd of housed dairy goats was characterized by severe granulomatous conjunctivitis and ipsilateral parotid and submandibular lymphadenopathy. In one case submitted for postmortem examination, Yersinia pseudo tuberculosis was isolated from both the conjunctiva and submandibular lymph node. Histopathological examination identified severe chronic active suppurative and lymphoplasmacytic conjunctivitis and suppurative and necrotizing lymphadenitis associated with bacteria of yersinial morphology. Similar pathological changes occur in Parinaud's oculoglandular syndrome in man due to infection with Y. pseudotuberculosis. Crown Copyright (C) 2009 Published by Elsevier Ltd. All rights reserved.
