  1. Values represent the means ±SD for three analyses of 20 μg of bacterial DNA. dptB−(pWHU746) is the dptB− mutant complemented with pWHU746, containing dndB with the promoter. p values were determined using a two-sided Student’s test for samples compared to wild-type S. enterica serovar Cerro 87.
