  • prfA mutant bacteria could still be seen associated with cells by phase-contrast microscopy at 4 hours post-infection (Figure 1d), albeit at much lower levels than wild-type or actA bacteria as they were no longer replicating.

  • For the prfA analysis, wild-type and actA were a single class.

  • The prfA gene codes for a transcriptional regulator, which controls the virulence genes hly, plcA, plcB, mpl and actA , as well as negatively regulating itself [ 31, 32].

  • To this end, we carried out similar 8-hour time courses with an isogenic L. monocytogenes strain deficient in actA (DP-L1942, Δ actA ), which is unable to nucleate actin polymerization and hence has no capacity for intracellular motility and intercellular spread [ 30].

  • The actA internal in-frame deletion mutant (DP-L1942) [ 30], which cannot initiate the polymerization of actin, was used to assess transcriptional responses specific to the motility phase of infection.
