Flavobacterium columnare ATCC 49512

Flavobacterium columnare ATCC 49512 is a Gram-negative, rod-shaped bacterium recognized for its pathogenicity specifically in fish. This organism is classified as a chemoheterotroph, indicating that it derives its energy from organic compounds, and it exhibits facultative anaerobic respiration, allowing it to thrive in various oxygen conditions. The bacterium is mesophilic, meaning it prefers moderate temperature ranges, which aligns with the environmental conditions typical of many aquatic habitats where it is found. Flavobacterium columnare is motile due to the presence of flagella, facilitating its movement within its diverse habitats. Notably, Flavobacterium columnare does not form spores, which suggests a reliance on other survival strategies under adverse conditions. With one replicon in its genome, it has a relatively simple genetic organization compared to more complex organisms. Ecologically, the presence of Flavobacterium columnare in aquatic environments can have significant implications for fish populations, as it is known to be a pathogen affecting various fish species. Outbreaks of disease caused by this bacterium can lead to substantial economic losses in aquaculture and impact natural fish populations. Understanding the traits and ecological role of Flavobacterium columnare is crucial for managing fish health and developing strategies to mitigate its pathogenic effects.
