Evaluation of a Recombinant Flavobacterium columnare DnaK Protein Vaccine as a Means of Protection Against Columnaris Disease in Channel Catfish (Ictalurus punctatus) [PDF]

Frontiers in Immunology, 2019
Flavobacterium columnare causes substantial losses among cultured finfish species. The Gram-negative bacterium is an opportunistic pathogen that manifests as biofilms on the host's mucosal surfaces as the disease progresses.

Comparative genomic analysis of Flavobacterium species causing columnaris disease of freshwater fish in Thailand: insights into virulence and resistance mechanisms [PDF]

BMC Veterinary Research
Background Columnaris disease, a prevalent disease among farmed and wild freshwater fish, is caused by the Flavobacterium columnare group, which includes four distinct species: F. columnare, F. oreochromis, F. covae, and F. davisii.

Genomic evidence of genetic diversity and functional evolution in Flavobacterium columnare [PDF]

Frontiers in Microbiology, 2023
Flavobacterium columnare is the causative agent of columnaris disease in freshwater fish. Columnaris disease can cause heavy economic losses in aquaculture. In this study, whole-genome sequencing was used to characterize this pathogen. F.

Metabarcoding Reveals a Potentially Undescribed Columnaris-Causing Bacterium in Peracute Skin Disease of Rainbow Trout (Oncorhynchus mykiss, Walbaum). [PDF]

J Fish Dis
ABSTRACT 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
