Identification of Four Distinct Phylogenetic Groups in Flavobacterium columnare With Fish Host Associations

Frontiers in Microbiology, 2018
Columnaris disease, caused by the Gram-negative bacterium Flavobacterium columnare, is one of the most prevalent fish diseases worldwide. An exceptionally high level of genetic diversity among isolates of F.

Invasion ability and disease dynamics of environmentally growing opportunistic pathogens under outside-host competition.

PLoS ONE, 2014
Most theories of the evolution of virulence concentrate on obligatory host-pathogen relationship. Yet, many pathogens replicate in the environment outside-host where they compete with non-pathogenic forms. Thus, replication and competition in the outside-

Genomic evidence of genetic diversity and functional evolution in Flavobacterium columnare

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.

Short-term feed deprivation alters immune status of surface mucosa in channel catfish (Ictalurus punctatus).

PLoS ONE, 2013
Short-term feed deprivation (or fasting) is a common occurrence in aquacultured fish species whether due to season, production strategies, or disease. In channel catfish (Ictalurus punctatus) fasting impacts susceptibility to several bacterial pathogens ...

Immunogenic proteins and their vaccine development potential evaluation in outer membrane proteins (OMPs) of Flavobacterium columnare

Aquaculture and Fisheries, 2016
Flavobacterium columnare is a Gram-negative bacterium that causes columnaris disease in freshwater fish worldwide. Many studies have focused on the identification of protective antigens to aid in the development of novel vaccines against the disease.

Potential of low-density genotype imputation for cost-efficient genomic selection for resistance to Flavobacterium columnare in rainbow trout (Oncorhynchus mykiss)

Genetics Selection Evolution, 2023
Background Flavobacterium columnare is the pathogen agent of columnaris disease, a major emerging disease that affects rainbow trout aquaculture. Selective breeding using genomic selection has potential to achieve cumulative improvement of the host ...

Secreted peptidases contribute to virulence of fish pathogen Flavobacterium columnare

Frontiers in Cellular and Infection Microbiology, 2023
Flavobacterium columnare causes columnaris disease in freshwater fish in both natural and aquaculture settings. This disease is often lethal, especially when fish population density is high, and control options such as vaccines are limited.
