Genetic fingerprinting of Flavobacterium columnare isolates from cultured fish

Journal of Applied Microbiology, 2004
To evaluate the intraspecific diversity of the fish pathogen Flavobacterium columnare.Genetic variability among Fl. columnare isolates was characterized using restriction fragment length polymorphism analysis of the 16S rDNA gene, intergenic spacer region (ISR) sequencing, and amplified fragment length polymorphism (AFLP) fingerprinting.

The influence of salmon surface mucus on the growth of Flavobacterium columnare

Journal of Fish Diseases, 2007
Abstract Flavobacterium columnare is the causative agent of columnaris disease. The presence of lesions on the gills, skin and fins of diseased fish suggests that F. columnare is able to utilize fish skin mucus as a substrate for growth and that exposure to this material would alter the expression of genes involved in the colonization of the outer ...

Isolation and characterization of strains of Flavobacterium columnare from Brazil

Journal of Fish Diseases, 2005
Abstract Flavobacterium columnare is an important pathogen of freshwater fish, implicated in skin and gill disease, often causing high mortality. An outbreak of skin disease in fingerling and adult Nile tilapia, Oreochromis niloticus (L.), cultivated in a recirculation system, was investigated.

Environment may be the source of Flavobacterium columnare outbreaks at fish farms

Environmental Microbiology Reports, 2012
Summary Flavobacterium columnare , causing columnaris disease, was isolated for the first time from free water and biofilms in the environment outside fish farms. Fourteen isolates were found from Central Finland from a river by a water intake of a salmonid farm and 400 m upstream of the farm ...

Activity of Lycorine Analogues against the Fish Bacterial Pathogen Flavobacterium columnare

Journal of Agricultural and Food Chemistry, 2011
In a continuing effort to discover natural products and natural product-based compounds for the control of columnaris disease in channel catfish (Ictalurus punctatus), 17 lycorine analogues were synthesized, including new benzoyl analogues 6-16, and evaluated for antibacterial activity against two isolates (ALM-00-173 and BioMed) of Flavobacterium ...

Activities of Wogonin Analogs and Other Flavones against Flavobacterium columnare

Chemistry & Biodiversity, 2015
AbstractIn our on‐going pursuit to discover natural products and natural product‐based compounds to control the bacterial species Flavobacterium columnare, which causes columnaris disease in channel catfish (Ictalurus punctatus), we synthesized flavone and chalcone analogs, and evaluated these compounds, along with flavonoids from natural sources, for ...

Host-specific association between Flavobacterium columnare genomovars and fish species

Systematic and Applied Microbiology, 2007
A total of 90 Flavobacterium columnare isolates were recovered from predominant wild fish species in the Mobile River, Alabama, USA. Isolates were identified and confirmed by fatty acid methyl ester analysis and specific PCR amplification. Genomovar ascription was performed using 16S-restriction fragment length polymorphism (RFLP) analysis.

Flavobacterium columnare genomovar influences mortality in channel catfish (Ictalurus punctatus)

Veterinary Microbiology, 2008
Flavobacterium columnare, causal agent of columnaris disease, is pathogenic to many species of freshwater fish throughout the world. The United States channel catfish (Ictalurus punctatus) aquaculture industry is severely impacted by columnaris disease. The majority of the F. columnare isolates recovered from diseased channel catfish belonged to either

The influence of competition on the formation of phage resistance in Flavobacterium columnare

2021
Bacteria live in complex communities, where they interact with other bacteria and also bacterial viruses, bacteriophages (phages). During the long coevolution between bacteria and phages, bacteria have developed various immunity mechanisms against phage infections. These mechanisms include CRISPR-Cas and surface modification, which have both been found
