Identification of Yersinia species


Public health England has issued “UK Standards for Microbiology Investigations ID 21: identification of Yersinia species.”

Members of the genus Yersinia are Gram-negative, catalase-positive and oxidase-negative, facultatively anaerobic straight rods to coccobacilli. Cells are 0.5 - 0.8μm by 1-3μm in size and show bipolar staining (“closed safety-pin appearance”). They have both respiratory and fermentative type of metabolism.

The document provides guidance about the identification of these organisms. To access the document, see Public Health England.
