Summary for Patent: 4,925,789
Title: Method and medium for use in detecting target microbes in situ in a specimen sample of a possibly contaminated material
Abstract:The presence or absence of a predetermined target microbe in a sample is determined by adding a testing medium to the sample, or vice versa. The testing medium provides a selective growth medium for the target microbe and includes a specific nutrient which only the target microbe can metabolize. This specific nutrient is modified by attaching a sample-altering moiety thereto, thereby converting the nutrient to a nutrient-indicator. The sample-altering moiety is activated to alter the sample only if the specific nutrient is metabolized by the target microbe. The sample-altering moiety can be a material which changes the color of the sample (visible or non-visible) or changes an electrical characteristic of the sample, or alters some other detectable characteristic of the sample. The testing media does not have to be kept sterile, and the testing procedure does not have to be performed in a sterile environment.
