Abstract

Five strains of gram-negative and yellow-pigmented bacteria were recently isolated from diseased freshwater fishes in Korea. All isolates were confirmed as a known fish pathogen of columnaris disease, Cytophaga columnaris based on their colonial and cellular morphology, and on physiological, biochemical and antigenic characteristics. Although the isolates were from different fish species, their characteristics of them were very similar to those of the reference strains of C columnaris (NCMB $2248^T$ and EK 28). Also, profiles of OMPs of Korean isolates were similar to those of the reference strain, C columnaris NCMB $2248^T$ when analyzed by SDS-PAGE.
