Secreted Extracellular Products of Flavobacterium covae as Potential Immunogenic Factors for Protection against Columnaris Disease in Channel Catfish (Ictalurus punctatus) [PDF]
Pathogens, 2023 Columnaris disease caused by Flavobacterium covae leads to substantial economic losses in commercially important fish species worldwide. The US channel catfish (Ictalurus punctatus) industry is particularly vulnerable to this disease. Therefore, there is

The Use of Kaolin as a Prophylactic Treatment to Prevent Columnaris Disease (Flavobacterium covae) in Commercial Baitfish and Sportfish Species [PDF]
Veterinary Sciences, 2023 Aquaculture farms in Arkansas, USA routinely battle columnaris disease caused by Flavobacterium covae. Columnaris is prevalent during stressful events such as feed training and when fish are stocked at high densities in holding vats before sale.

Deciphering the Molecular Basis for Attenuation of Flavobacterium columnare Strain Fc1723 Used as Modified Live Vaccine against Columnaris Disease [PDF]
Vaccines, 2021 Vaccines are widely employed in aquaculture to prevent bacterial infections, but their use by the U.S. catfish industry is very limited. One of the main diseases affecting catfish aquaculture is columnaris disease, caused by the bacterial pathogen ...

Metabarcoding Reveals a Potentially Undescribed Columnaris-Causing Bacterium in Peracute Skin Disease of Rainbow Trout (Oncorhynchus mykiss, Walbaum). [PDF]
J Fish DisABSTRACT Columnaris‐causing bacteria (CCB) represent a group of four Flavobacterium species, previously classified under Flavobacterium columnaris, causing a threatening condition in salmonid farming characterised by cutaneous and gill lesions, commonly referred to as ‘saddleback disease’. A peracute skin disease outbreak with high mortality in rainbow
