Abstract

Twenty four cultures of Vibrio anguillarum and V. ordalii exhibited two or three different colony types on tryptone soya agar supplemented with 1% (w/v) sodium chloride and marine 2216E agar. Cells from these colony types demonstrated variable pathogenicity for salmonids, and possessed a range of Gram-staining intensities and micromorphologies. Generally, the different colony types gave identical reactions in the API 20E rapid identification system. The only exceptions concerned the lack of gelatinase activity by two colony types of two isolates.
