Abstract
This study used whole-genome sequencing to analyze the first case of NDM-1-producing Acinetobacter baumannii belonging to the novel sequence type 1465/CC216 recovered in Brazil. The study identified an unusual plasmid carrying blaNDM-1 gene, in which some genes of the Tn125 transposon were lost. Besides, on the chromosome, the strain reported here presented blaOXA-106 gene, a variant of blaOXA-51 gene, and blaADC-25 with ISAba1 upstream. The isolation of new STs of A. baumannii carrying blaNDM-1 genes elicits our concerns about the possible spread of these genes among clinically relevant bacteria.
