A major challenge in bacterial pathogenesis is understanding the molecular basis of the switch from saprophytism to virulence. Following a recent whole-genome transcriptomic analysis using tiling arrays, an article published in BMC Genomics reports the first use of RNA-seq in Listeria monocytogenes in order to identify genes controlled by sigma B, a transcriptional regulator with a critical role in virulence.
