- Abstract
The increasing prevalence and dissemination of carbapenemase-producing Enterobacterales represent a serious concern for public health. We studied the genetic features of a multidrug-resistant isolate of high-risk clone ST147 Klebsiella pneumoniae coharboring mcr -1 and bla recovered from a human clinical urine sample in 2017 in Peru. Whole-genome sequencing and conjugation assays identified
NDM-1 recovered from a human clinical urine sample in 2017 in Peru. Whole-genome sequencing and conjugation assays identified mcr-1 and blaNDM-1 genes on two different conjugative plasmids, which belong to IncI2 and IncFIB/HI1B incompatibility groups, respectively. The presence of blaCTX-M-15 (in the studied isolate, located on the chromosome) and mutations in GyrA S83I and ParC S80I were detected, as expected for ST147. In addition, other β-lactamases ( blaTEM-26 and blaOXA-1 ) and PMQR ( qnrE2 and aac(6')-Ib-cr ) among several resistance determinants were identified. The coexistence not previously described of these genes in the same high-risk clone is a cause for serious concern that supports the need for implementation of genomic surveillance studies.- Published
