Flavobacterium psychrophilum strain CSF259-93

Flavobacterium psychrophilum strain CSF259-93 is a psychrophilic, aerobic, rod-shaped bacterium that serves as a significant pathogen in aquatic environments. It is classified as a chemoheterotroph, deriving its energy from organic compounds. The strain has a specific optimal growth temperature of 15°C, reflecting its adaptation to cold-water habitats where it thrives. This bacterium is non-motile and possesses flagella, which may play a role in its adherence to surfaces in its aquatic environment. It has a single replicon and is not capable of sporulation, indicating a stable genetic structure and a reliance on other survival strategies in its cold habitats. Flavobacterium psychrophilum primarily affects fish species, notably Oncorhynchus mykiss (rainbow trout) and other members of the Salmonidae family. The pathogen is associated with bacterial cold water disease and rainbow trout fry syndrome, both of which can lead to significant health issues in fish populations, impacting aquaculture and wild fish communities. The presence of this bacterium in multiple habitats highlights its ecological significance, particularly in colder aquatic ecosystems. Understanding the traits and impacts of Flavobacterium psychrophilum strain CSF259-93 can provide insights into disease management in fisheries and the health of aquatic organisms in cold environments.
