RmtC and RmtF 16S rRNA methyltransferase in NDM-1–producing Pseudomonas aeruginosa

Abstract

We investigated 16S rRNA methyltransferases in 38 blaNDM-1–positive Pseudomonas aeruginosa isolates and found RmtC in 3 isolates, 1 of which also harbored RmtF. The isolates were clonally unrelated; rmtC and rmtF genes were located on a chromosome with the blaNDM-1 gene. Strategies are needed to limit the spread of such isolates.
