Eastern white-tailed deer as a reservoir of ruminant paratuberculosis

Abstract

SUMMARY Ten white-tailed deer were shot and killed at a Connecticut farm that had a 6-year history of bovine paratuberculosis, and organs from these animals were examined for evidence of paratuberculosis. Mycobacterium paratuberculosis was isolated from the cecal lymph node, terminal ileum, and ileocecal valve of 1 deer and from the cecal lymph node of another. Characteristic lesions and acid-fast bacilli were not observed. It was concluded that infected deer could serve as sources of infection for domestic stock.
