Abstract

The name Flavobacterium branchiophila is proposed for a group of 16 bacterial strains that were isolated in Japan (5 isolates), Oregon (10 isolates), and Hungary (1 isolate) from cultured salmonids or sheatfish suffering from bacterial gill disease. These bacteria grow in cytophaga medium at temperatures between 10 and 25°C. The isolates are gram-negative, nonmotile, slender rods measuring 0.5 by 5 to 8 μm. They utilize gelatin, casein, starch, glucose, fructose, sucrose, maltose, and trehalose. The mean guanine-plus-cytosine content of the deoxyribonucleic acids of three selected strains was 30 mol %. Strain BGD-7721 (= ATCC 35035) is designated the type strain of the new species.
