Yersinia enterocolitica is a small pleomorphic gram-negative, non–spore-forming coccobacillus that has been classified into 6 biotypes and more than 60 serotypes. The serotypes most often associated with human disease are 0:3, 0:5, 0:8, 0:9, 0:13, and 0:27. Human illness can occur after consumption of Y enterocolitica–contaminated food, animal waste, and unchlorinated water. This organism may survive and grow during refrigerated storage. Human illness ranges from self-limited enteritis to potentially life-threatening systemic infection.
