Representatives of the genus Flavobacterium have colonized a wide variety of temperate and polar habitats in terrestrial, freshwater, and marine environments. They are likely of high importance for the turnover/degradation of organic matter in these ecosystems. Hence, members of the genus Flavobacterium have recently acquired important ecological interest. In addition, some strains may have biotechnological applications owing to the production of cold-adapted enzymes and to their potential for bioremediation or wastewater treatment. Although most members of the genus are environmental bacteria, three Flavobacterium species are serious fish pathogens that severely impact freshwater aquaculture worldwide. Bacterial gill disease (BGD) is characterized by the presence of numerous bacteria on the surface of the gill epithelium that severely affect the respiratory function of infected fish.

Flavobacterium branchiophilum (strain FL-15) is a Gram-negative bacterium isolated from a diseased sheatfish (Silurus glanis) in Hungary. F. branchiophilum is the main causative agent of bacterial gill disease, a severe condition affecting various cultured freshwater fish species worldwide, in particular salmonids in Canada and Japan. In contrast with F. psychrophilum and F. columnare, F. branchiophilum is a fastidious, nongliding organism with a unique tropism for the gill epithelium and is usually not isolated from internal organs. The disease is characterized by explosive morbidity and mortality attributable to massive bacterial colonization of gill lamellar surfaces, causing irritation and fusion of gill filaments and lamellae. The subsequent necrosis of the gills rapidly impairs the respiratory and osmoregulatory functions. (Adapted from PMID: 21926215).
