Abstract:
A method for detecting, quantifying, and differentiating colonies of Aeromonas from selected other biological entities in a test sample, said method comprising the following steps: providing a base medium including ions of a salt, a &bgr;-D-galactoside substrate that forms a first component of a first color in the presence of a first enzyme, and an &agr;-D-galactoside substrate that forms a second component of a second color distinguishable from said first color in the presence of a second enzyme; inoculating the test medium with a test sample; incubating the test medium; and examining the test medium whereby aggregations of colonies of Aeromonas are indicated by said first color, and aggregations of colonies of Salmonella are indicated by said second color, and whereby colonies of general coliforms are indicated by a third color, said third color being a combination of said first and second colors.
