FIG 2.

Inhibition effects of environmental matrix on the detection of S. marcescens. The dashed line indicates the quantification cycle (Cq) for the seeded quantity of plasmids (104). The bars (with standard deviation error bars) represent each sample type with seeded plasmids (n = 3). Significant inhibition (*) was recorded for the undiluted sewage influent sample (P = 0.0124).
