This species is motile, positive for urease, and ornithine decarboxylase, and negative for oxidase, and citrate. It is able to ferment cellobiose, sucrose, and sorbose but not raffinose, melibiose, or rhamnose. Y. enterocolitica is commensal and a pathogen that causes Yersiniosis, which infects children that have ingested contaminated meat or milk.
