Abstract
Two multidrug-resistant (MDR) mcr-1-harboring Klebsiella pneumoniae isolates from patients with urinary tract infections and one MDR Klebsiella quasipneumoniae isolate from a patient with bloodstream infection were identified to carry tmexCD1-toprJ1 The addition of the efflux pump inhibitor reduced the tigecycline MIC against all three isolates by 8- to 16-fold. pKQBSI104-1 was transferred from K. quasipneumoniae to Escherichia coli J53 via conjugation. The tmexCD1-toprJ1-carrying plasmids pKP15ZE495-1 (102,569 bp) and pKQBSI104-1 (121,996 bp) were completely sequenced and analyzed.Entities:
