Claims14
A method for determining the presence or absence of a particular strain of microorganism in a culture medium, said method comprising:
- introducing at least two chromogens which are enzyme substrates for said strain into said culture medium, said chromogens selected so that, in said culture medium, the presence of said strain is revealed by an accessory color, said accessory color having a dominant wavelength different than a dominant wavelength of the chromophore corresponding to each of the chromogens and different than a dominant wavelength of the mixture of the chromophore of each of the chromogens;
- and
- identifying the presence of said strain by identifying said accessory color.
