Duration of Heat Stress Effect on Invasiveness of L. monocytogenes Strains

Figure 2

Relative change in the transcription level for inlA, inlB, sigB, and prfA genes for heat-treated and nontreated strain L71. Fold changes and SD were calculated from 3 independent RNA preparations and PCRs performed in duplicate. The data were analyzed by two-way ANOVA followed by a Bonferroni test.
