The role of denitrification genes in anaerobic growth and virulence of Flavobacterium columnare [PDF]
Journal of Applied Microbiology, 2021 Comparative genomics analyses indicated that the Flavobacterium columnare genome has unique denitrification genes relative to Flavobacterium psychrophilum and Flavobacterium johnsoniae, including nasA (nitrate reductase), nirS (nitrite reductase), norB (nitric oxide reductase) and nosZ (nitrous oxide reductase).

Transcriptome analysis of the fish pathogen Flavobacterium columnare in biofilm suggests calcium role in pathogenesis [PDF]
BMC Microbiology, 2019 Background Flavobacterium columnare is the causative agent of columnaris disease that affects cultured freshwater fishes worldwide. F. columnare easily colonizes surfaces by forming biofilm, which helps the pathogen resist antibiotic and disinfectant ...

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.
