Causes and Effects of Columnaris-type Diseases in Fish: Columnaris Disease in Roach and Perch from English Waters

Nature, 1967
Diseases affecting salmon, sea-trout and coarse fish and characterized by the occurrence of skin lesions have been recognized for some time in the rivers of England, Scotland and Ireland. During 1966 there were epidemics in parts of Ireland as well as Cumberland, Lancashire and southern counties of England.

Columnaris as a Disease of Cold-Water Fishes

Transactions of the American Fisheries Society, 1945
Abstract A natural outbreak of columnaris disease among wild adult and hatchery-reared fingerling salmon in the State of Washington is described. The disease is identified by the recovery of the causative organism, Bacillus columnaris Davis, which may be readily identified by its characteristic action in forming columns on the surfaces of infected ...

Development of a bivalent mucoadhesive nanovaccine to prevent francisellosis and columnaris diseases in Nile tilapia (Oreochromis niloticus)

Fish and Shellfish Immunology, 2023
The occurrence of francisellosis caused by Francisella orientalis sp. nov. (Fo) and columnaris disease caused by Flavobacterium oreochromis (For) is negatively impacting Nile tilapia (Oreochromis niloticus) production, especially when high stocking densities are used.

Gill Infection Model for Columnaris Disease in Common Carp and Rainbow Trout

Journal of Aquatic Animal Health, 2014
Abstract Challenge models generating gill lesions typical for columnaris disease were developed for the fry of both Common Carp Cyprinus carpio and Rainbow Trout Oncorhynchus mykiss by means of an immersion challenge and Flavobacterium columnare field isolates were characterized regarding virulence.

Can Fucoidan Decrease the Mortalities Caused by Columnaris Disease in Nile Tilapia? [PDF]

World Journal of Agricultural Research, 2017
Columnaris disease is a serious disease in warm water fish. It is caused by Flavobacterium columnare, a Gram-negative bacterium. In this work, fucoidan was tested for its efficacy in decreasing the mortalities caused by Columnaris disease in Nile tilapia.

Pretreating Channel Catfish with Copper Sulfate Affects Susceptibility to Columnaris Disease

North American Journal of Aquaculture, 2013
Abstract Columnaris disease is one of the most important bacterial diseases affecting Channel Catfish Ictalurus punctatus commercially grown in the USA. This disease can greatly diminish the profitability of aquaculture operations by large-scale mortality events, particularly in the fingerling production phase.

Use of Vaccination against Enteric Septicemia of Catfish and Columnaris Disease by the U.S. Catfish Industry

Journal of Aquatic Animal Health, 2012
Abstract Vaccination is an effective strategy used for the protection of food animals against infectious diseases. A 2010 U.S. Department of Agriculture questionnaire examined U.S. catfish industry use (in 2009) of two commercial vaccines that provide protection against enteric septicemia of catfish (ESC) and columnaris disease, catfish ...

Diversity of Non-Flavobacterium columnare Bacteria Associated with Columnaris-like Diseased Fish

The Thai Journal of Veterinary Medicine, 2016
Numerous yellow and pink pigmented bacterial isolates had been recovered from diseased fish exhibiting columnaris-like disease in tilapia (Oreochromis spp.) farms in Thailand. The predominant species had been identified as Flavobacterium columnare while taxonomic classification of the remaining isolates and their pathogenic potential remain ...

Columnaris disease of cultured carp Cyprinus carpio L. Characterization of the causative agent

Aquaculture, 1976
Abstract A carp disease, initially diagnosed as carp erythrodermatitis (CE), has occurred enzootically since 1972 at a hatchery near Lelystad, The Netherlands. Gliding bacteria belonging to the Cytophaga family were repeatedly isolated from external lesions in affected carp.

Development of mucoadhesive nanovaccine against columnaris disease in red tilapia (Oreochromis sp.)

2023
Tilapia (Oreochromis sp.) is very important and high production of freshwater fish in Thailand. Columnaris disease has been now recognized as one of the most serious infectious diseases in farmed tilapia. The disease is caused by Flavobacterium columnare.
