Effect of PEMAX on serial dilutions of live <i>Salmonella</i> cells in the presence of dead cells.

<p>Serial dilutions of live <i>Salmonella</i> cells (5.0×10⁷ to 5.0×10³ cfu) in the presence of 5.0×10⁷ dead <i>Salmonella</i> cells were treated with 0 μM (white bars) or 100 μM (grey bars) PEMAX followed by real-time PCR. The control samples contains either 5.0×10⁷ live or dead cells (no mixed population). Means, standard deviations (n = 4) and the linear regression equation and R² value of PEMAX treated samples are depicted. * In 3 of 4 dead samples treated with PEMAX no PCR signal were detected, therefore only the PCR signal of 1 sample is indicated in the diagram.</p
