Hemorrhagic necrotizing enterocolitis associated with Clostridium difficile infection in four foals

Abstract

Severe hemorrhagic necrotizing enterocolitis was determined to be the cause of death for 4 foals. Toxigenic Clostridium difficile was isolated form the intestine of each foal, and large, gram-positive, rod-shaped bacteria lined the surface of necrotic villi. This finding of toxigenic C difficile associated with enteritis in foals adds another possible cause to the list of infectious agents that should be considered when evaluating foals with enteritis. Definitive diagnosis requires a thorough diagnostic evaluation, including procedures that will identify the organism and demonstrate its toxigenicity.
