Decoding the genetic structure of conjugative plasmids in international clones of Klebsiella pneumoniae: A deep dive into blaKPC, blaNDM, blaOXA-48, and blaGES genes.

ABSTRACT: Carbapanem-resistant Klebsiella pneumoniae is a globally healthcare crisis. The distribution of plasmids carrying carbapenemase genes among K. pneumoniae poses a serious threat in clinical settings. Here, we characterized the genetic structure of plasmids harboring major carbapenemases (e.g. blaKPC, blaNDM, blaOXA-48-like, and blaGES) from K. pneumoniae using bioinformatics tools. The plasmids carrying at least one major carbapenemase gene were retrieved from the GenBank database. The DNA length, Inc type, and conjugal apparatus of these plasmids were detected. Additionally, allele types, co-existence, co-occurrence of carbapenemase genes, gene repetition, and sequence types of isolates, were characterized. There were 2254 plasmids harboring carbapenemase genes in the database. This study
