Abstract
A process for detecting viable waterborne pathogens in a water sample, includes enriching at least a portion of the sample with an enrichment broth and taking a first DNA extract at time Tand a second DNA extract at time Tafter an incubation period. Real-time polymerase chain reaction performed on the DNA extracts yields respective cycle threshold values Ct. The change in Ct provides an indication of viability of the targeted pathogen in the sample. An order of magnitude quantification of the sample can also be performed using a serial dilution technique on the TDNA extract. The process has particular application for detecting, including viable but not culturable cells.
