Insights into incompatible plasmids in multidrug-resistant Raoultella superbugs.

ABSTRACT: The emergence of multidrug-resistant (MDR) Raoultella isolates is linked to the acquisition of antibiotic resistance genes (ARGs) with plasmids playing a pivotal role in this process. While plasmid-mediated transmission of ARGs in Raoultella has been extensively reported, limited attention has been given to genetically dissecting the modular structures of plasmids. This study aims to elucidate the genomic features of novel incompatible plasmids in MDR Raoultella by presenting 13 complete plasmid sequences from four isolates, along with an analysis of 16 related plasmids from GenBank. These 29 plasmids were classified into five distinct groups: IncFII single-replicon plasmids, dual-replicon plasmids containing the IncFII replicon, IncHI plasmids, IncR plasmids, and IncX8 plasmids.
