An improved assay for rapid detection of viable Staphylococcus aureus cells by incorporating surfactant and PMA treatments in qPCR.

ABSTRACT:

Background

Staphylococcus aureus is an important human pathogen causing a variety of life-threatening diseases. Rapid and accurate detection of Staphylococcus aureus is a necessity for prevention of outbreaks caused by this pathogen. PCR is a useful tool for rapid detection of foodborne pathogens, however, its inability to differentiate DNA from dead cells and live cells in amplification severely limits its application in pathogen detection. The aim of this study was to develop an improved assay was developed by incorporating the sample treatments with a surfactant and propidium monoazide (PMA) in qPCR for detection of viable S. aureus cells.

Results

The cell toxic effect testing with the two surfactants showed that the viability of S. aureus was virtually not affected by th
