The cell surface hydrophobicity of Renibacterium salmoninarum strains was examined using a salt aggregation method. Those strains which were virulent in the test animal were sticky, auto‐agglutinating and possessed a hydrophobic cell surface. Those strains with a low virulence were non‐sticky, non‐agglutinating and failed to aggregate in a high molar salt. Strains could not be distinguished using biochemical tests. There was no change in hydrophobicity following re‐isolation of the bacteria from experimentally infected rainbow trout, Salmo gairdneri .
