Differentially expressed genes induced by each pathogen. (A) Total upregulated and downregulated genes by each pathogen are represented as fold change values compared to the expression of the non-infected sample. (B) Comparison of specific and common induction of differentially expressed genes by each pathogen alone and by all three. Listeria monocytogenes induces the strongest common and specific gene regulation of all three pathogens fallowed by S. aureus and S. pneumoniae. LM: L. monocytogenes EGDe, SA: S. aureus, SP: S. pneumoniae.
