Flavobacterium columnare

Flavobacterium columnare is a Gram-negative, rod-shaped bacterium characterized by its motility, which is facilitated by the presence of true flagella. This non-sporulating organism exhibits facultative anaerobic respiration, indicating its ability to thrive in both the presence and absence of oxygen. As a mesophilic microbe, it prefers moderate temperature ranges for optimal growth, reflecting its adaptability to varied environmental conditions. Flavobacterium columnare is classified as a chemoheterotroph, relying on organic compounds for energy and carbon. Its habitat is diverse, suggesting a wide ecological distribution, although specific environments are not detailed in the available data. Notably, this bacterium is recognized for its pathogenicity in fish, which underscores its ecological significance within aquatic ecosystems. The genomic information for Flavobacterium columnare is accessible under accession number OLKH00000000.1, indicating a well-defined genetic framework that could be explored for further understanding of its biology and interactions within its habitat. The presence of a single replicon in its genome reflects a streamlined genetic organization, which may be advantageous for its survival and adaptability in dynamic environments. This bacterium's multifaceted role in aquatic ecology and its impact on fish health highlight the intricate relationships between microorganisms and their hosts in aquatic systems.
