^aSurvival of water-treated controls was set at 100% for each strain. There were no significant differences when data from the pkaR C′ strain were compared with those from the wild type.

^bP < 0.001 compared with results for ΔpkaR strain.

^cP < 0.01 compared with results for ΔpkaR strain.

^dP < 0.05 compared with results for ΔpkaR strain.
