Fig. 2From: An improved assay for rapid detection of viable Staphylococcus aureus cells by incorporating surfactant and PMA treatments in qPCRDetection of viable cells of S. aureus in the presence of a large number of dead cells by the PMA-qPCR. The numbers on the X axis (1–5) represent the number of live cells in the samples (0, 1.0 × 102, 5.0 × 103, 1.0 × 104, and 2.0× 105 CFU/ml, respectively), mixed with 2.0 × 105 CFU/ml dead cellsBack to article page
