Turton JF, Perry C, McGowan K, Turton JA, Hope R. Klebsiella pneumoniae sequence type 147: a high-risk clone increasingly associated with plasmids carrying both resistance and virulence elements. J Med Microbiol 2024; 73:001823. [PMID: 38629482 PMCID: PMC11084618 DOI: 10.1099/jmm.0.001823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 03/18/2024] [Indexed: 04/19/2024] Open
Abstract
Introduction. The first hybrid resistance/virulence plasmid, combining elements from virulence plasmids described in hypervirulent types of Klebsiella pneumoniae with those from conjugative resistance plasmids, was described in an isolate of sequence type (ST) 147 from 2016. Subsequently, this type has been increasingly associated with these plasmids.Hypothesis or gap statement. The extent of carriage of hybrid virulence/resistance plasmids in nosocomial isolates of K. pneumoniae requires further investigation.Aim. To describe the occurrence of virulence/resistance plasmids among isolates of K. pneumoniae received by the UK reference laboratory, particularly among representatives of ST147, and to compare their sequences.Methodology. Isolates received by the laboratory during 2022 and the first half of 2023 (n=1278) were screened for virulence plasmids by PCR detection of rmpA/rmpA2 and typed by variable-number tandem repeat analysis. Twenty-nine representatives of ST147 (including a single-locus variant) from seven hospital laboratories were subjected to long-read nanopore sequencing using high-accuracy q20 chemistry to provide complete assemblies.Results. rmpA/rmpA2 were detected in 110 isolates, of which 59 belonged to hypervirulent K1-ST23, K2-ST86 and K2-ST65/375. Of the remainder, representatives of ST147 formed the largest group, with 22 rmpA/rmpA2-positive representatives (out of 47 isolates). Representatives were from 19 hospital laboratories, with rmpA/rmpA2-positive isolates from 10. Nanopore sequencing of 29 representatives of ST147 divided them into those with no virulence plasmid (n=12), those with non-New Delhi metallo-β-lactamase (NDM) virulence plasmids (n=6) and those carrying bla NDM-5 (n=9) or bla NDM-1 (n=2) virulence plasmids. These plasmids were of IncFIB(pNDM-Mar)/IncHI1B(pNDM-MAR) replicon types. Most of the non-NDM virulence plasmids were highly similar to the originally described KpvST147L_NDM plasmid. Those carrying bla NDM-5 were highly similar to one another and to previously described plasmids in ST383 and carried an extensive array of resistance genes. Comparison of the fully assembled chromosomes indicated multiple introductions of ST147 in UK hospitals.Conclusion. This study highlights the high proportion of representatives of ST147 that carry IncFIB(pNDM-Mar)/IncHI1B(pNDM-MAR) hybrid resistance virulence plasmids. It is important to be aware of the high probability that representatives of this type carry these plasmids combining resistance and virulence determinants and of the consequent increased risk to patients.

First detection in Spain of NDM-1-producing Pseudomonas aeruginosa in two patients transferred from Ukraine to a university hospital. J Glob Antimicrob Resist 2024; 36:105-111. [PMID: 38159724 DOI: 10.1016/j.jgar.2023.12.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 12/21/2023] [Accepted: 12/21/2023] [Indexed: 01/03/2024] Open
Abstract
OBJECTIVES Carbapenemase-mediated carbapenem resistance in Pseudomonas aeruginosa is a relevant health problem. We detected for the first time in Spain two clinical NDM-producing P. aeruginosa (NDM-Pa) isolates in two Ukrainian patients admitted to our hospital between April and August 2022. METHODS Antimicrobial susceptibility was studied by microdilution and MIC gradient strips (EUCAST-2022 criteria). Carbapenemase genes were detected by the Xpert Carba-R and immunochromatography assays. WGS (Illumina and Oxford-Nanopore) was also performed. RESULTS In May 2022, we detected an NDM-Pa in a sternotomy wound in a patient. In June-2022, a second NDM-Pa along with an OXA-48-Klebsiella pneumoniae (OXA-48-Kp) isolate was detected in a mandibular abscess from an unrelated patient. Moreover, an NDM+OXA-48-K. pneumoniae (NDM+OXA-48-Kp) was also found in a rectal sample of this patient. Both patients had undergone surgery in Ukraine before their transfer to our hospital. NDM-Pa isolates were resistant to all tested antimicrobials with the exception of aztreonam (MIC = 8 mg/L), colistin (MIC =2 mg/L) and cefiderocol (MIC range = 0.75-2 mg/L). WGS confirmed that both P. aeruginosa isolates were NDM-1 producers, belonged to ST773 and shared an identical resistome. blaNDM-1 was located on a ∼117-Kb chromosomally integrated integrative conjugative element (ICE). OXA-48-Kp and NDM+OXA-48-Kp belonged to ST147 and contained blaOXA-48 on an identical ∼300-Kb IncHIB-plasmid. blaNDM-1 was located on a 51-Kb IncFIB-plasmid only found in NDM+OXA-48-Kp. CONCLUSIONS This is the first description of NDM-Pa in Spain. We highlight the threat of further cross-border dissemination of NDM-1 through P. aeruginosa along with K. pneumoniae high-risk clones also carrying OXA-48, which draws a complex epidemiological scenario.

Abstract
Klebsiella pneumoniae (Kpn) is an opportunistic pathogen that causes intrahospital complications such as pneumonia, liver abscesses, soft tissue infections, urinary infections, bacteraemia, and, in some cases, death. Since this bacterium has a higher frequency than other Gram-negative pathogens, it has become an important pathogen to the health sector. The adaptative genome of Kpn likely facilitates increased survival of the pathogen in diverse situations. Therefore, several studies have been focused on developing new molecules, synergistic formulations, and biomaterials that make it possible to combat and control infections with and dispersion of this pathogen. Note that the uncontrolled antibiotic administration that occurred during the pandemic led to the emergence of new multidrug-resistant strains, and scientists were challenged to overcome them. This review aims to compile the latest information on Kpn that generates intrahospital infections, specifically their pathogenicity-associated factors. Furthermore, it explains the natural-product-based treatments (extracts and essential oils) developed for Kpn infection and dispersion control.

Abstract
To investigate the acquisition and relatedness of New Delhi Metallo-beta-lactamase among multiple separate species from one patient. Five isolates from three species (Pseudomonas aeruginosa; Pa, Acinetobacter baumannii; Ab and Proteus mirabilis; Pm) suspected of harbouring a carbapenemase were investigated by phenotype (antimicrobial susceptibilities) and whole genome sequencing. Epidemiological data was collected on this patient. Three different carbapenemase genes were detected; blaVIM-1 (Pa; ST773), blaOXA-23 (Ab, ST499) and blaNDM-1 identified in all isolates. NDM regions were found chromosomally integrated in all isolates. Data showed no evidence of NDM-1 transfer within this patient suggesting the enzyme was acquired in three separate events.

High-Molecular-Weight Plasmids Carrying Carbapenemase Genes blaNDM-1, blaKPC-2, and blaOXA-48 Coexisting in Clinical Klebsiella pneumoniae Strains of ST39. Microorganisms 2023; 11:microorganisms11020459. [PMID: 36838424 PMCID: PMC9961262 DOI: 10.3390/microorganisms11020459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 02/07/2023] [Accepted: 02/09/2023] [Indexed: 02/15/2023] Open
Abstract
BACKGROUND Klebsiella pneumoniae, a member of the ESKAPE group of bacterial pathogens, has developed multi-antimicrobial resistance (AMR), including resistance to carbapenems, which has increased alarmingly due to the acquisition of carbapenemase genes located on specific plasmids. METHODS Four clinical K. pneumoniae isolates were collected from four patients of a neuro-intensive care unit in Moscow, Russia, during the point prevalence survey. The AMR phenotype was estimated using the Vitec-2 instrument, and whole genome sequencing (WGS) was done using Illumina and Nanopore technologies. RESULTS All strains were resistant to beta-lactams, nitrofurans, fluoroquinolones, sulfonamides, aminoglycosides, and tetracyclines. WGS analysis revealed that all strains were closely related to K. pneumoniae ST39, capsular type K-23, with 99.99% chromosome identity. The novelty of the study is the description of the strains carrying simultaneously three large plasmids of the IncHI1B, IncC, and IncFIB groups carrying the carbapenemase genes of three types, blaOXA-48, blaNDM-1, and blaKPC-2, respectively. The first of them, highly identical in all strains, was a hybrid plasmid that combined two regions of the resistance genes (blaOXA-48 and blaTEM-1 + blaCTX-M-15 + blaOXA-1 + catB + qnrS1 + int1) and a region of the virulence genes (iucABCD, iutA, terC, and rmpA2::IS110). CONCLUSION The spread of K. pneumoniae strains carrying multiple plasmids conferring resistance even to last-resort antibiotics is of great clinical concern.
