Yersinia enterocolitica

Yersinia enterocolitica is a Gram-negative, rod-shaped bacterium characterized by its motility, which is facilitated by true flagella. This microbe exhibits a single-cell arrangement and is nonsporulating. As a facultative anaerobe, Y. enterocolitica can thrive in both the presence and absence of oxygen, and it primarily adopts a heterotrophic mode of nutrition. Optimal growth occurs at 28°C, positioning it within the mesophilic temperature classification. The bacterium possesses a complex cellular structure, featuring two membranes, and it contains three replicons within its genome. The genome accessions associated with Y. enterocolitica include CGBR00000000.1, CQCV00000000.1, and CQDZ00000000.1, suggesting a well-characterized genetic framework. Yersinia enterocolitica is known to inhabit multiple environments, indicating its versatility and adaptability. As a free-living organism, it plays a role in various ecological contexts, which may contribute to its persistence in diverse habitats. This adaptability, along with its defined growth conditions and nutritional requirements, underscores the ecological significance of Y. enterocolitica in its native environments.
