Flavobacteria, a Never Ending Threat for Fish: a Review

Purpose of Review In this review, we summarized the most recent findings on the partial and full genome and the phylogenetic structure of genomovars, as well as on virulence factors, vaccine development, and treatment methods of the two fish pathogenic bacteria Flavobacterium psychrophilum and F. columnare

Scholarcy highlights

  • Flavobacteria are considered to be important fish pathogens throughout the world
  • F. psychrophilum is known as the causative agent of bacterial coldwater disease and rainbow trout fry syndrome, F. branchiophilum causes
  • Great efforts have been invested to unravel the genetic background of both F. psychrophilum and F. columnare, where full genomes as well as parts thereof have been analyzed by different techniques
  • Vaccinated ayu was bath challenged with F. psychrophilum, and the results revealed a protective effect in challenged ayu
  • Despite all the efforts to disclose pathogen mechanisms and to find suitable methods to prevent or treat infection, the two bacteria still represent a major threat to aquaculture, both in temperate and warm climate zones, and effective, internationally registered vaccines are still lacking
  • Reported die-offs from wild fish populations illustrate the importance of these pathogens
