Yersinia pseudotuberculosis strain NCTC8580

Yersinia pseudotuberculosis strain NCTC8580 is a Gram-negative, rod-shaped bacterium that displays a facultative anaerobic metabolism, allowing it to thrive in diverse habitats. This strain is heterotrophic, deriving energy from organic compounds. The cells are typically found as singles and possess flagella, which contribute to their mobility. Optimal growth occurs at 28°C, encompassing a mesophilic temperature range. Notably, Y. pseudotuberculosis NCTC8580 has a single replicon and two membranes, characteristic of its classification within the Enterobacteriaceae family. In terms of biotic relationships, this bacterium is free-living and has been identified in various hosts, including Homo sapiens (humans), Sus scrofa (pigs), Daucus carota (carrots), Aves (birds), and Acanthamoeba castellanii (a type of amoeba). This host diversity suggests that Y. pseudotuberculosis may have complex ecological interactions within different environments. The strain is associated with several health effects in humans, including bacteremia, liver abscess, sepsis, diarrhea, gastroenteritis, and pseudoappendicitis, among others. These health impacts underscore its pathogenicity and potential to cause significant gastrointestinal diseases, particularly yersiniosis. Understanding the ecological niches and host interactions of Yersinia pseudotuberculosis NCTC8580 can provide insight into its transmission dynamics and the potential risks it poses to both animal and human health. Its ability to inhabit multiple environments and infect various hosts highlights the importance of monitoring this pathogen in epidemiological studies.
