Yersinia ruckeri strain NCTC10476

Yersinia ruckeri strain NCTC10476 is a rod-shaped bacterium that exhibits the presence of flagella, facilitating motility in aquatic habitats. It is notably associated with salmonid fish, particularly Oncorhynchus mykiss (rainbow trout), making it an important pathogen within the Salmonidae family. This strain has been linked to significant health issues in these hosts, including septicemia and Enteric Red Mouth Syndrome (ERMS), also known as enteric red mouth disease. The bacterium's habitat primarily includes the gills of fish, where it can cause infections leading to severe disease manifestations. Yersinia ruckeri possesses a single replicon, which is characteristic of its genomic structure. The presence of this pathogen in aquatic environments poses a considerable risk to fish populations, as it can lead to high mortality rates among affected individuals. Understanding the ecological role of Yersinia ruckeri, particularly in relation to its impact on salmonid fish, is crucial for managing fish health in aquaculture and natural ecosystems. The disease caused by this bacterium not only affects the health of individual fish but can also have broader implications for fish populations and the aquatic food web. Effective management strategies are essential to mitigate the effects of ERMS and protect both wild and cultivated salmonid stocks.
