[PMID: 39170056 PMCID: PMC11336059 DOI: 10.1002/ece3.70121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2024] [Accepted: 07/23/2024] [Indexed: 08/23/2024] Open
Abstract
Plasmids incur a fitness cost that has the potential to restrict the dissemination of resistance in bacterial pathogens. However, bacteria can overcome this disadvantage by compensatory evolution to maintain their resistance. Compensatory evolution can occur via both chromosomes and plasmids, but there are a few reviews regarding this topic, and most of them focus on plasmids. In this review, we provide a comprehensive overview of the currently reported mechanisms underlying compensatory evolution on chromosomes and plasmids, elucidate key targets regulating plasmid fitness cost, and discuss future challenges in this field. We found that compensatory evolution on chromosomes primarily arises from mutations in transcriptional regulatory factors, whereas compensatory evolution of plasmids predominantly involves three pathways: plasmid copy number regulation, conjugation transfer efficiency, and expression of antimicrobial resistance (AMR) genes. Furthermore, the importance of reasonable selection of research subjects and effective integration of diverse advanced research methods is also emphasized in our future study on compensatory mechanisms. Overall, this review establishes a theoretical framework that aims to provide innovative ideas for minimizing the emergence and spread of AMR genes.

Increase in antioxidant capacity associated with the successful subclone of hypervirulent carbapenem-resistant Klebsiella pneumoniae ST11-KL64. Nat Commun 2024; 15:67. [PMID: 38167298 PMCID: PMC10761919 DOI: 10.1038/s41467-023-44351-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 12/11/2023] [Indexed: 01/05/2024] Open
Abstract
The acquisition of exogenous mobile genetic material imposes an adaptive burden on bacteria, whereas the adaptational evolution of virulence plasmids upon entry into carbapenem-resistant Klebsiella pneumoniae (CRKP) and its impact remains unclear. To better understand the virulence in CRKP, we characterize virulence plasmids utilizing a large genomic data containing 1219 K. pneumoniae from our long-term surveillance and publicly accessible databases. Phylogenetic evaluation unveils associations between distinct virulence plasmids and serotypes. The sub-lineage ST11-KL64 CRKP acquires a pK2044-like virulence plasmid from ST23-KL1 hypervirulent K. pneumoniae, with a 2698 bp region deletion in all ST11-KL64. The deletion is observed to regulate methionine metabolism, enhance antioxidant capacity, and further improve survival of hypervirulent CRKP in macrophages. The pK2044-like virulence plasmid discards certain sequences to enhance survival of ST11-KL64, thereby conferring an evolutionary advantage. This work contributes to multifaceted understanding of virulence and provides insight into potential causes behind low fitness costs observed in bacteria.
