ABSTRACT:
Methods and kits for detecting the presence of and quantifying the concentration of viable microorganisms in a liquid sample are provided. Enzymes present in viable microorgansims reduce an indicator reagent to produce a visible color change. No titrations or dilutions of the sample are necessary. Variations of the test are described which can be used to detect a threshold level of viable microorganisms, to detect the presence or absence of viable microorganisms and to quantify the concentration of viable microorganisms in a liquid sample. The results are obtained rapidly with those for the detection available within thirty minutes and those for the quantification available within thirteen hours.
