Representative results from flow cytometry analyses of dead cell staining of co-culture and control cultures. Upper panel: L.monocytogenes were either co-cultured with LAB (a, b) or cultured without LAB (control, c, d), and evaluated for dead cells (identified within P3) by PI staining as defined in Fig. 1. Dead cells (within P3) comprised 9.1% of P1- gated L.monocytogenes from co-cultures (b), whereas only 1.8% of P1-gated L.monocytogenes cells were identified as dead cells in control cultures (d). Lower panel: S. Enteritidis were either co-cultured with LAB (a, b) or cultured without LAB (control, c, d), and evaluated for dead cells (identified within P3) by PI staining as defined in Fig. 1. Dead cells (within P3) comprised 91% of P1-gated S. Enteritidis from co-cultures (b), whereas 60% of P1-gated S. Enteritidis cells were identified as dead cells in control cultures (d)
