Abstract Motile Aeromonas hydrophila strains were recovered from several freshwater sources by spread-plating water samples on starch-ampicillin agar, originally described as a medium for recovering Aeromonas hydrophila quantitatively from foods. Starch-ampicillin agar was compared with membrane Aeromonas medium and Rimler-Shotts medium for selectivity for, and recovery of, Aeromonas strains from freshwater. Thirty-four Aeromonas strains thus isolated were identified to species level by their phenotypic characteristics, and the Mol% G+C of representative strains was determined. Although resistant to 10 μg of the vibriostatic agent 0/129, all these strains showed sensitivity to 150 μg 0/129, which brings into question the use of this agent for distinguishing aeromonads from vibrios. The ability of these strains to produce extracellular virulence factors was generally similar to that reported for environmental strains isolated by other methods from various geographical locations within and beyond Australia. Ten of the 20 A. sobria strains, but none of the A. hydrophila or A. caviae strains, produced enterotoxin as shown by the suckling mouse test. Haemolysin was produced by 9/10 of the enterotoxigenic A. sobria strains and 2/9 A. hydrophila strains. Hemagglutinating activity was detected in 5/20 A. sobria and 7/9 A. hydrophila strains, and was inhibited by fucose and mannose, but not by galactose. The characteristics of these strains were comparable with those of Aeromonas strains isolated from other freshwater environments apart from their sensitivity to 0/129.
