Fig. 6From: Virulence characterization and comparative genomics of Listeria monocytogenes sequence type 155 strainsmRNA expression of inlA (a), inlB (b), actA (c), hly (d) and prfA (e) of L. monocytogenes ScottA variant, L23–13, P06_14 and Ro09. Values were normalized to 16S rRNA expression levels and are represented as x-fold of the ScottA variant. Data represent mean values ± SD of three biological replicates, performed in triplicates and measured in duplicates. * statistically significant differences compared to the control strain ScottA variant (p < 0.05)Back to article page
