Rapid and Accurate Detection of Bacteriophage Activity against Escherichia coli O157:H7 by Propidium Monoazide Real-Time PCR

Figure 1

Comparison of accuracy of direct plating and qPCR for pure cultures of viable E. coli O157:H7 R508N cells. The difference between direct plating and qPCR was not significant () and the correlation coefficient was 0.94. Each point presents the mean ± standard deviation of two independent replicates.
