Figure 2From: Development of a sensitive and specific qPCR assay in conjunction with propidium monoazide for enhanced detection of live Salmonellaspp. in foodDiscrimination of live Salmonella cells from live/dead cell mixtures. Dead cells at concentration of 3 × 106 CFU/g were mixed with different number of live cells as indicated and treated with PMA or without PMA. Results were the average of three independent assays with triplicates ± standard deviation.Back to article page
