This
is a rapid bioluminogenic test method for the detection and enumeration of
total population of bacteria or total contamination in a sample (down to 1 CFU)
providing results in less than 8 hours. MicroSnap TOTAL consists of an
Enrichment Swab Device containing proprietary growth medium and a Detection
Device containing bioluminogenic reagents in which biomarkers produced by
bacteria are measured using a small portable luminometer. The two step
test procedure requires a short incubation period to enhance the growth of
bacteria followed by the detection step. During incubation in the Enrichment
broth, the number of bacteria is increased and potential sample interference is
reduced. As the bacteria grow they use up their available food resources in the
broth and generate enzymatic biomarkers, such that the greater the number of
bacteria, the higher the biomarker concentration after a set time interval.
Subsequently, the biomarker produced by living and growing bacteria is measured
using a luminometer. The light output is directly proportional to the
concentration of biomarkers and number of bacteria present.[ A relationship
between biomarker concentration at a specific point and starting numbers of
mixed bacteria can be established.] MicroSnap TOTAL can be used to test
environmental surfaces, foodstuff, water and other filterable liquids. The test
should be run using aseptic techniques in a laboratory or in a controlled
environment.
