Four isolates of the non‐motile species Aeromonas media , icluding the type strain, were demonstrated by transmission electronk microcopy to possess polar flagella. Motility appeared to be restricted to old, regularly subcultured strains, and coincided with an increase in colony size and a concomitant reduction in the amount of brown diffusible pigment produced by colonies on tryptone soya agar.
