arnT mRNA expression levels in CST-susceptible and -heteroresistant ECC. SMEnt52 (E. hormaechei subsp. steigerwaltii, hsp60 cluster VIII) and SMEnt513 (E. kobei, hsp60 cluster II) were used as CST-susceptible and -resistant isolates, respectively. A arnT mRNA expression levels during cultivation of SMEnt52 and SMEnt513 in the presence (16 mg/L) and absence of CST. The y axis shows relative expression levels normalized by that at 0 min (set to 1.0). *p < 0.05 and **p < 0.001. B arnT mRNA expression levels in SMEnt52 and SMEnt513 cultivated in the presence of various CST concentrations. Total RNA was isolated after cultivation for 45 min at 37 ℃. The y axis shows relative mRNA expression levels normalized by that in SMEnt52 in the absence of CST (set to 1.0). *p < 0.05 and **p < 0.001
