General Characteristics
Y. pestis is a rod-shaped facultative anaerobe with bipolar staining (giving it a safety pin appearance). Similar to other Yersinia members, it tests negative for urease, lactose fermentation, and indole. The closest relative is the gastrointestinal pathogen Yersinia pseudotuberculosis, and more distantly Yersinia enterocolitica.
