Definition of Term
A genus of gram-negative bacteria of the Vibrionaceae. Cells are variable, straight round-ended rods or coccobacilli (0.3-1.0 x 1.0-3.5 µm) - occuring singly, in pairs or in short chains - or short filaments. The genus is divided into two groups: non-motile psychrotrops (A. salmonicida) and motile mesophiles (A. hydrophila group). Motile cells usually have a single, polar, unsheathed flagellum (wavelength ca. 1.7 µm). Aeromonas spp. Are oxidase +ve. The taxonomy of the motile strains remains unsettled.
