id 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 diseaseBacterial cold water diseaseFlavobacterium psychrophilum is a member of the Flavobacteriaceae family. It is a gram-negative rod-shaped bacterial pathogen that can cause bacterial cold water disease in salmonid fish. The disease typically occurs at temperatures below 13⁰C, and disease can be seen in any area with water...
