Cytophaga

Species

• Cytophaga columnaris — the cause of columnaris disease in salmonid fish, as associated with increased water temperature; it is characterized by white necrotic plaques overlaying skin ulcers; formerly called: Flexibacter columnaris.
• Cytophaga johnsonae — associated with false columnaris disease.
• Cytophaga psychrophila — causes peduncle or cold water disease in Brook trout; predisposed by subnormal water temperature.
• Cytophaga hutchinsonii --- aerobic cellulolytic soil bacterium that is known for its ability to rapidly glide over surfaces. The mechanism of cellulose digestion is not fully known; however, it is known that C. hutchinsonii has multiple cell-associated cellulolytic enzymes.
