Fig 7. Transcriptional regulation by CcpA and HptRS mediate antibiotic susceptibility.
Antibiotic susceptibility was investigated using antibiotic disks on TSA. Data represent the mean and standard error of the mean of the zone of inhibition (edge of the disk to the first colony) for 3 biological replicates. Significant differences (p ≤ 0.05) between SA564-ΔccpA and SA564-ΔhptRS/ccpA are represented with an (*).
