abstract：:We recently identified a novel plasmid-mediated RND-type efflux pump gene cluster, tmexCD1-toprJ1 in Klebsiella pneumoniae, that conferred resistance to multiple antimicrobials, including tigecycline. While homologs of tmexCD1-toprJ1 were found encoded in many other bacterial species in GenBank, their function and tra...
