Yersinia pseudotuberculosis

Yersinia pseudotuberculosis is a Gram-negative, rod-shaped bacterium characterized by its motility, facilitated by true flagella. This microbe exhibits a facultative anaerobic metabolism and is classified as a heterotroph, relying on organic compounds for energy and growth. It is mesophilic, with an optimal growth temperature of 28°C, and displays a free-living biotic relationship, indicating its ability to thrive in various environments. The bacterium possesses two cellular membranes and three replicons, which contribute to its genetic and physiological diversity. Yersinia pseudotuberculosis is notable for its pathogenicity in humans, establishing itself as a significant agent of disease. Its habitat spans multiple ecological niches, demonstrating its adaptability and potential for survival in diverse conditions. This organism's ability to thrive in various habitats and its pathogenic potential highlight its ecological versatility and the importance of monitoring its presence in environments where human exposure may occur.
