neural injuries in ischemic rats.Cefiderocol is a cephalosporin antibiotic presenting expanded antimicrobial activity. CirA is a gateway for cefiderocol to enter bacterial cells. We found that cirA1 and cirA198 were primary alleles in Klebsiella pneumoniae. CirA1 exhibited higher iron-transporting ability than CirA198 in iron-limited conditions. The cefiderocol minimum inhibitory concentration (MIC) increased from 0.5 mg/L to 2 mg/L when cirA1 was mutated to cirA198. Consistently, the MIC showed a 4-fold decrease when cirA19
