Identification of Plasmid-Encoded sRNAs in a blaNDM-1-Harboring Multidrug-Resistance Plasmid pNDM-HK in Enterobacteriaceae
Small RNAs (sRNAs) play significant roles in regulating gene expression post-transcriptionally in response to environmental changes in bacteria. In this work, we identified and characterized six novel sRNAs from an emerging multidrug-resistance (MDR) plasmid pNDM-HK, a New Delhi metallo-β-lactamase 1 gene (blaNDM−1)-carrying IncL/M plasmid that has caused worldwide threat in recent years. These...
متن کاملResistance plasmid families in Enterobacteriaceae.
Bacteria carry extrachromosomal, self-replicating genetic elements called plasmids. A plasmid is defined as a doublestranded, circular DNA molecule capable of autonomous replication. By definition, plasmids do not carry genes essential for the growth of host cells under nonstressed conditions (109). Plasmids have systems which guarantee their autonomous replication but also have mechanisms cont...
متن کاملComplete Genome Sequence of a Klebsiella pneumoniae Strain Carrying blaNDM-1 on a Multidrug Resistance Plasmid
Here, we report the genome sequence of a blaNDM-1-positive Klebsiella pneumoniae AATZP isolate cultured from a perirectal surveillance swab collected upon admission of a patient to the NIH Clinical Center in 2014. Genome sequencing of this isolate revealed three plasmids, including one carrying the blaNDM-1 gene encoding resistance to carbapenems.
متن کاملCharacterization of a blaNDM-1-harboring plasmid from a Salmonella enterica clinical isolate in China
The plasmid-mediated transmission of antibiotic resistance genes has been reported to be involved in the development of antibiotic resistance in bacteria, and poses a serious threat for the success of bacterial infection treatment and human health worldwide. The present study used a 454 GS‑FLX pyrosequencing system to determine the ~140 kb nucleotide sequence of plasmid pHS36‑NDM, which was ide...
متن کاملNDM-1 encoded by a pNDM-BJ01-like plasmid p3SP-NDM in clinical Enterobacter aerogenes
A carbapenem-nonsusceptible Enterobacter aerogenes strain named 3-SP was isolated from a human case of pneumonia in a Chinese teaching hospital. NDM-1 carbapenemase is produced by a pNDM-BJ01-like conjugative plasmid designated p3SP-NDM to account for carbapenem resistance of 3-SP. p3SP-NDM was fully sequenced and compared with all publically available pNDM-BJ01-like plasmids. The genetic diffe...
