ECAR assays performed independently in quadruplicate reveal significantly lower ECARs of S. Typhimurium ΔyqiC from the 9th to 26th cycle after incubation relative to those of its paternal wild-type strain SL1344 and yqiC-complemented strain ΔyqiC'. ECARs obtained in the absence of ampicillin (A) and following injection of ampicillin at 28 min (B) (*p < 0.05 and **p < 0.01 for comparisons between ΔyqiC and SL1344; ⁺p < 0.05 and ⁺⁺p < 0.01 for comparisons between ΔyqiC and ΔyqiC')
