Hours postinoculation (hpi).
GUS activity is shown in μmol of 4-methylumbelliferyl produced min−1 109 CFU−1. Data represent the means of three measurements ± standard errors. Similar results were obtained in a second independent experiment.
Fold induction is shown as GUS activity at 24 or 48 hpi/GUS activity at 0 hpi.
dspE promoter in opposite direction from uidA gene.
dspE promoter in correct direction toward uidA gene.
UL, under detection limit of vector control.
sav2932 encodes a hypothetical protein and is not listed in Table 2.
