Figure 2From: Acid shock of Listeria monocytogenes at low environmental temperatures induces prfA, epithelial cell invasion, and lethality towards Caenorhabditis elegansprfA induction levels in L. monocytogenes strains. The transcriptional change of the prfA mRNA from five additional L. monocytogenes strains belonging to serotypes 1/2a, 3a and 4b at 18°C and 60 min after acid shock to pH 5.0 was measured by qRT-PCR in three independent experiments. The value for strain EGDe from Figure 1 is given in the last column as reference.Back to article page
