^a Aeromonas colonies were harvested from plates at the sample concentration used for calculation of viable count, and from other plates which were lower concentrations than the plates used for calculation
^bThere are difficult isolates that distinguish A. hydrophila from A. bestiarum
^cThere are difficult isolates that distinguish A. caviae from A. media
^dUnidentified ADH(+) is Aeromonas spp. of arginin dehydrolase (ADH) positive
^eUnidentified ADH(−) is Aeromonas spp. of arginin dehydrolase (ADH) negative
