Relative changes in expression for virulence-associated genes from the LEE Pathogenecity Island. A. Expression differences of 5 genes transported through or adherence components of the LEE island as determined by Q-PCR. B. Expression differences of 3 genes encoding effectors (Esp) molecules transported through the LEE Type III Secretion System (TTSS) as determined by Q-PCR results. Average changes in expression for 2 independent replicate cultures were determined relative to the transcript level of each ORF at the 3 h mid-exponential phase time point.
