Antibiotics (Basel) 2024; 13:682. [PMID: 39199982 PMCID: PMC11350871 DOI: 10.3390/antibiotics13080682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Revised: 07/19/2024] [Accepted: 07/19/2024] [Indexed: 09/01/2024] Open
Abstract
The worldwide emergence and dissemination of carbapenem-resistant Gram-negative bacteria (CRGNB) is a challenging problem of antimicrobial resistance today. Outbreaks with CRGNB have severe consequences for both the affected healthcare settings as well as the patients with infection. Thus, bloodstream infections caused by metallo-ß-lactamase-producing Enterobacterales can often have clinical implications, resulting in high mortality rates due to delays in administering effective treatment and the limited availability of treatment options. The overall threat of CRGNB is substantial because carbapenems are used to treat infections caused by ESBL-producing Enterobacterales which also exist with high frequency within the same geographical regions. A genome-based surveillance of 589 CRGNB from 61 hospitals across the federal state Hesse in Germany was implemented using next-generation sequencing (NGS) technology to obtain a high-resolution landscape of carbapenem-resistant isolates over a three-year period (2017-2019). The study examined all reportable CRGNB isolates submitted by participating hospitals. This included isolates carrying known carbapenemases (435) together with carbapenem-resistant non-carbapenemase producers (154). Predominant carbapenemase producers included Klebsiella pneumoniae, Escherichia coli, Citrobacter freundii and Acinetobacter baumannii. Over 80% of 375 carbapenem-resistant determinants including KPC-, NDM-, VIM- and OXA-48-like ones detected in 520 Enterobacterales were plasmid-encoded, and half of these were dominated by a few incompatibility (Inc) types, viz., IncN, IncL/M, IncFII and IncF(K). Our results revealed that plasmids play an extraordinary role in the dissemination of carbapenem resistance in the heterogeneous CRGNB population. The plasmids were also associated with several multispecies dissemination events and local outbreaks throughout the study period, indicating the substantial role of horizontal gene transfer in carbapenemase spread. Furthermore, due to vertical and horizontal plasmid transfer, this can have an impact on implant-associated infections and is therefore important for antibiotic-loaded bone cement and drug-containing devices in orthopedic surgery. Future genomic surveillance projects should increase their focus on plasmid characterization.

Transmission of global clones of NDM-producing Enterobacterales and interspecies spread of IncX3 plasmid harbouring bla NDM-5 in Tokyo. J Glob Antimicrob Resist 2024; 38:309-316. [PMID: 39004343 DOI: 10.1016/j.jgar.2024.06.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 06/05/2024] [Accepted: 06/21/2024] [Indexed: 07/16/2024] Open
Abstract
OBJECTIVE The aim of this study is to characterise the molecular characteristics of NDM-producing Enterobacterales, which have been on the increase in recent years in Japan, where IMP-producing bacteria are dominant among carbapenemase-producing Enterobacterales. METHODS We collected 21 strains of NDM-producing Enterobacterales detected between 2015 and 2022 at five hospitals in Tokyo and performed illumina whole genome sequencing. For the seven selected strains, nanopore long-read sequencing was also performed to characterise the plasmids harbouring blaNDM. RESULTS Fourteen strains were Escherichia coli and all carried blaNDM-5. Among these strains, eight and three were sequence type (ST) 410 and ST167, respectively, and both groups of strains were spread clonally in different hospitals. Two strains of Klebsiella pneumoniae ST147 carrying blaNDM-1 were detected in a hospital, and these strains had also spread clonally. The remainder included Enterobacter hormaechei, Klebsiella quasipneumoniae, Citrobacter amalonaticus, and Klebsiella michiganensis. Plasmid analysis revealed that an identical IncX3 plasmid harbouring blaNDM-5 was shared among four strains of different bacterial species (E. coli, C. amalonaticus, K. michiganensis, and E. hormaechei) detected at the same hospital. In addition, a Klebsiella quasipneumoniae strain detected at a different hospital also carried an IncX3 plasmid with a similar genetic structure. CONCLUSIONS Nosocomial spread of multiple multidrug-resistant global clones and transmission of IncX3 plasmids harbouring blaNDM-5 among multiple species were detected as the major pathways of spread of NDM-producing Enterobacterales in Tokyo. Early detection of carriers and measures to prevent nosocomial spread are important to prevent further spread of NDM-producing organisms.

Abstract
Background To limit the use of antimicrobials without disincentivising the development of novel antimicrobials, there is interest in establishing innovative models that fund antimicrobials based on an evaluation of their value as opposed to the volumes used. The aim of this project was to evaluate the population-level health benefit of cefiderocol in the NHS in England, for the treatment of severe aerobic Gram-negative bacterial infections when used within its licensed indications. The results were used to inform the National Institute for Health and Care Excellence guidance in support of commercial discussions regarding contract value between the manufacturer and NHS England. Methods The health benefit of cefiderocol was first derived for a series of high-value clinical scenarios. These represented uses that were expected to have a significant impact on patients' mortality risks and health-related quality of life. The clinical effectiveness of cefiderocol relative to its comparators was estimated by synthesising evidence on susceptibility of the pathogens of interest to the antimicrobials in a network meta-analysis. Patient-level costs and health outcomes of cefiderocol under various usage scenarios compared with alternative management strategies were quantified using decision modelling. Results were reported as incremental net health effects expressed in quality-adjusted life-years, which were scaled to 20-year population values using infection number forecasts based on data from Public Health England. The outcomes estimated for the high-value clinical scenarios were extrapolated to other expected uses for cefiderocol. Results Among Enterobacterales isolates with the metallo-beta-lactamase resistance mechanism, the base-case network meta-analysis found that cefiderocol was associated with a lower susceptibility relative to colistin (odds ratio 0.32, 95% credible intervals 0.04 to 2.47), but the result was not statistically significant. The other treatments were also associated with lower susceptibility than colistin, but the results were not statistically significant. In the metallo-beta-lactamase Pseudomonas aeruginosa base-case network meta-analysis, cefiderocol was associated with a lower susceptibility relative to colistin (odds ratio 0.44, 95% credible intervals 0.03 to 3.94), but the result was not statistically significant. The other treatments were associated with no susceptibility. In the base case, patient-level benefit of cefiderocol was between 0.02 and 0.15 quality-adjusted life-years, depending on the site of infection, the pathogen and the usage scenario. There was a high degree of uncertainty surrounding the benefits of cefiderocol across all subgroups. There was substantial uncertainty in the number of infections that are suitable for treatment with cefiderocol, so population-level results are presented for a range of scenarios for the current infection numbers, the expected increases in infections over time and rates of emergence of resistance. The population-level benefits varied substantially across the base-case scenarios, from 896 to 3559 quality-adjusted life-years over 20 years. Conclusion This work has provided quantitative estimates of the value of cefiderocol within its areas of expected usage within the NHS. Limitations Given existing evidence, the estimates of the value of cefiderocol are highly uncertain. Future work Future evaluations of antimicrobials would benefit from improvements to NHS data linkages; research to support appropriate synthesis of susceptibility studies; and application of routine data and decision modelling to assess enablement value. Study registration No registration of this study was undertaken.

Abstract
IMPORTANCE Current infection control protocols assume that the spread of KPC-2 carbapenemase-producing Enterobacterales (KPC2-CPE) by detected carriers to other in-house patients is through clonal transmission and can be restricted by implementing containment measures. We examined the presence of the bla KPC-2 gene in different genera and species of Enterobacterales isolated from humans at different hospitals and surface waters between 2013 and 2019 in Germany. We found that a single IncN[pMLST15] plasmid carrying the bla KPC-2 gene on a novel non-Tn4401-element (NTEKPC-Y), flanked by an adjacent region encoding 12 other antibiotic resistance genes, was uniquely present in multiple species of KPC2-CPE isolates. These findings demonstrate the selective impact of specific IncN plasmids as major drivers of carbapenemase dissemination and suggest "plasmid-based endemicity" for KPC2-CPE. Studies on the dynamics of plasmid-based KPC2-CPE transmission and its presence in persistent reservoirs need to be urgently considered to implement effective surveillance and prevention measures in healthcare institutions.

Abstract
Carbapenem-resistant Escherichia coli (CREC) has become a major public health problem worldwide. To date, there is a limited understanding of the global distribution of CREC. In this study, we performed a comprehensive genomic analysis of 7, 731 CRECs of human origin collected from different countries worldwide between 2005 and 2023. Our results showed that these CRECs were distributed in 75 countries, mainly from the United States (17.49%), China (14.88%), and the United Kingdom (14.73%). Eight carbapenemases were identified among the CRECs analyzed, including KPC, IMP, NDM, VIM, OXA, FRI, GES, and IMI. NDM was the most predominant carbapenemase (52.15%), followed by OXA (30.09%) and KPC (14.72%). Notably, all CRECs carried multiple antibiotic resistance genes (ARGs), with 178 isolates carrying mcr-1 and 9 isolates carrying tet(X). The CREC isolates were classified into 465 known sequence types (STs), with ST167 being the most common (11.5%). Correlation analysis demonstrated the significant role of mobile genetic elements in facilitating the transfer of carbapenem resistance genes. Furthermore, some CRECs from different countries showed high genetic similarity, suggesting clonal transmission exists. According to the GWAS results, the genetic difference of blaNDM-positive CRECs from China were mainly enriched in bacterial Type IV secretion system pathways compared with those from the United Kingdom and the United States. Therefore, continuous global surveillance of CRECs is imperative in the future.

Abstract
Heavy metals such as zinc (Zn) and copper (Cu) may be associated with antibiotic resistance dissemination. Our aim was to investigate whether sub-lethal dosage of Zn and Cu may enhance plasmid transfer and subsequently resistance genes dissemination. Plasmid conjugation frequencies (PCF) were performed with Escherichia coli strains bearing IncL-blaOXA-48, IncA/C-blaCMY-2, IncI1-blaCTX-M-1, IncF-blaCTX-M-1, and IncX3-blaNDM-5 as donors. Mating-out assays were performed with sub-dosages of zinc oxide (ZnO) and Cu sulfate (CuSO4). Quantification of the SOS response-associated gene expression levels and of the production of reactive oxygen species were determined. Increased PCF was observed for IncL, IncA/C, and IncX3 when treated with ZnO. PCF was only increased for IncL when treated with CuSO4. The ROS production presented an overall positive correlation with PCF after treatment with ZnO for IncL, IncA/C, and IncX3. For CuSO4 treatment, the same was observed only for IncL. No increase was observed for expression of SOS response-associated genes under CuSO4 treatment, and under ZnO treatment, we observed an increase in SOS response-associated genes only for IncX3. Our data showed that sub-dosages of ZnO and CuSO4 could significantly enhance PCF in E. coli, with a more marked effect observed with IncL, IncA/C, and IncX3 scaffolds. Our study suggested that use of certain heavy metals is not the panacea for avoiding use of antibiotics in order to prevent the dissemination of antibiotic resistance.

Abstract
Background Relebactam, previously known as MK-7655, is currently being tested in combination with imipenem as a class A and class C β-lactamase inhibitor, including KPC from Klebsiella pneumoniae. Objective The objective of the current study was to evaluate the activity of imipenem/relebactam against gram-negative bacilli. Methods After applying exclusion and inclusion criteria, 72 articles with full texts that describe the prevalence of imipenem/relebactam resistance were chosen for the meta-analysis and systematic review. Articles published between January 2015 and February 2023 were surveyed. The systematic literature search was conducted in PubMed, Web of Science, Google Scholar, and Scopus. Results The pooled estimation of 282,621 sample isolates revealed that the prevalence rate of imipenem/relebactam resistance is roughly 14.6% (95% CI, 0.116%-0.182%). Conclusions The findings of this analysis show that imipenem/relebactam resistance is rare in the majority of developed countries. Given that relebactam has proven to restore the activity of imipenem against current clinical isolates, further research into imipenem/relebactam is necessary.

Abstract
Carbapenem resistance among Enterobacterales has become a global health concern. Clinical Escherichia coli isolates producing the metallo β-lactamase NDM have been isolated from two hospitals in Faisalabad, Pakistan. These E. coli strains were characterized by MALDI-TOF, PCR, antimicrobial susceptibility testing, XbaI and S1 nuclease pulsed-field gel electrophoresis (PFGE), conjugation assay, DNA hybridization, whole genome sequencing, bioinformatic analysis, and Galleria mellonella experiments. Thirty-four blaNDM producing E. coli strains were identified among 52 nonduplicate carbapenem-resistant strains. More than 90% of the isolates were found to be multidrug resistant by antimicrobial susceptibility testing. S1 PFGE confirmed the presence of blaNDM gene on plasmids ranging from 40 kbps to 250 kbps, and conjugation assays demonstrated transfer frequencies of blaNDM harboring plasmids ranging from 1.59 × 10-1 to 6.46 × 10-8 per donor. Whole genome sequencing analysis revealed blaNDM-5 as the prominent NDM subtype with the highest prevalence of blaOXA-1, blaCTX-M-15, aadA2, aac(6')-Ib-cr, and tet(A) associated resistant determinants. E. coli sequence types: ST405, ST361, and ST167 were prominent, and plasmid Inc types: FII, FIA, FIB, FIC, X3, R, and Y, were observed among all isolates. The genetic environment of blaNDM region on IncF plasmids included partial ISAba125, the bleomycin ble gene, and a class I integron. The virulence genes terC, traT, gad, fyuA, irp2, capU, and sitA were frequently observed, and G. mellonella experiments showed that virulence correlated with the number of virulence determinants. A strong infection control management in the hospital is necessary to check the emergence of carbapenem resistance in Gram-negative bacteria.IMPORTANCEWe describe a detailed analysis of highly resistant clinical E. coli isolates from two tertiary care centers in Pakistan including carbapenem resistance as well as common co-resistance mechanisms. South Asia has a huge problem with highly resistant E. coli. However, we find that though these isolates are very difficult to treat they are of low virulence. Thus the Western world has an increasing problem with virulent E. coli that are mostly of low antibiotic resistance, whereas, South Asia has an increasing problem with highly resistant E. coli that are of low virulence potential. These observations allow us to start to devise methodologies to limit both virulence and resistance and combat problems in developing nations as well as the Western world.

Abstract
Cefiderocol resistance is increasingly reported in New Delhi metallo-β-lactamase-producing Enterobacterales. Genomic and phenotypic analysis of Escherichia coli sequence type 361, a primary clone causing carbapenemase spread in France, revealed mutations leading to cefiderocol resistance. Continued genomic surveillance of carbapenem-resistant Enterobacterales could clarify prevalence of cefiderocol-resistant E. coli in Europe.

Abstract
Carbapenemase-producing in Enterobacterales (CPE) represent a critical health concern worldwide, including in Switzerland, leading to very limited therapeutic options. Therefore, our aim was to evaluate the susceptibility to the novel ß-lactam/ß-lactamase inhibitor combinations ceftazidime-avibactam, meropenem-vaborbactam, and imipenem-relebactam of CPE isolates recovered in Switzerland from 2018 to 2020. A total of 150 clinical CPE were studied including mainly Klebsiella pneumoniae (n = 61, 40.3%) and Escherichia coli (n = 53, 35.3%). The distribution of carbapenemases was as follows: KPC-like (32%), OXA-48-like (32%), NDM-like (24%), combinations of carbapenemases (10%), VIM-1 producers (n = 2), and a single IMI-1 producer. Overall, 77% of the strains were susceptible to meropenem-vaborbactam, 63% was susceptible to ceftazidime-avibactam, and 62% susceptible to imipenem-relebactam. Those data may contribute to optimize the choice of first line therapy for treating infections due to CPE.

Abstract
Background Cefiderocol and ceftazidime-avibactam plus aztreonam (CZA-ATM) are preferred treatment regimens for New Delhi metallo-β-lactamase (NDM)-producing infections. Methods We report the case of a US patient who traveled to India to receive a renal transplant. He subsequently experienced pyelonephritis by an NDM-producing Escherichia coli. Broth microdilution and the broth disk elution method indicated resistance to all β-lactams, including cefiderocol and CZA-ATM. Whole-genome sequencing investigations were undertaken to identify resistance mechanisms. Results An E. coli isolate belonging to sequence type (ST) 167 containing a blaNDM-5 gene was identified on a plasmid of the IncFIA/IncFIB/IncFIC replicon groups. When compared with the genome of another ST167 E. coli clinical isolate containing blaNDM-5 and exhibiting susceptibility to cefiderocol and CZA-ATM, a 12-base pair insertion in ftsI, translating to a 4-amino acid duplication in PBP3, was identified. Moreover, a blaCMY-59 gene was harbored on an IncI-γ replicon type, and frameshift mutations were identified in the cirA iron transport gene. Conclusions This is the first clinical case of a US patient harboring an NDM-producing isolate exhibiting resistance to all available β-lactam agents. The isolate's unexpected resistance to cefiderocol and CZA-ATM was likely due to a combination of (1) a modified PBP3 (increased MICs to both regimens), (2) truncated iron-binding protein (increased cefiderocol MIC), and (3) a blaCMY gene (reduced CZA-ATM activity). E. coli ST167 clinical isolates harboring blaNDM-5 genes are a recognized international high-risk clone. When coupled with the additional mechanisms identified in our patient's isolate, which is not uncommon for this high-risk clone, pan-β-lactam resistance may occur.

Abstract
The emergence and spread of carbapenemase genes, colistin resistance genes mcr-1, and tigecycline resistance gene tet(X) represent a significant threat to clinical therapy and public health. In this study, we investigated the presence of carbapenemase genes, mcr-1, and tet(X) in 298 Escherichia coli strains obtained from a teaching hospital in China. In total, eight (2.68%), six (2.01%), and one (0.34%) E. coli isolates carried blaNDM, mcr-1, and tet(X4), respectively. The blaNDM gene was located on IncX3 (n = 4), F2:A-:B- (n = 3), and F2:A1:B1 (n = 1) plasmids, with high similarity to multiple plasmids belonging to the same incompatibility type from Enterobacteriaceae. Six MCR-producing strains contained mcr-1-carrying IncI2 plasmids, organized similarly to other mcr-1-bearing IncI2 plasmids from animals in China. The blaCTX-M-55/64/132/199 gene located within a typical transposition unit (ISEcp1-blaCTX-M-orf477Δ) was inserted near dnaJ to generate 5-bp direct repeats in four mcr-1-positive plasmids. The tet(X) and another four resistance genes [aadA2, tet(A), floR, and Δlnu(F)] were co-located on an IncX1 plasmid, highly similar to other tet(X4)-carrying IncX1 plasmids from Escherichia and Klebsiella of animal or food origin, except that the conjugative transfer region of IncX1 plasmids was absent in our plasmid. Although a low prevalence of blaNDM, mcr-1, and tet(X) was observed in E. coli from patients in this study, their dissemination associated with some successful pandemic plasmids is of great concern. The continued surveillance of these crucial resistance genes in patients should be strengthened.

Abstract
Whole genome sequencing data of 874 Escherichia coli isolates carrying bla NDM-5 from 13 European Union/European Economic Area countries between 2012 and June 2022 showed the predominance of sequence types ST167, ST405, ST410, ST361 and ST648, and an increasing frequency of detection. Nearly a third (30.6%) of these isolates were associated with infections and more than half (58.2%) were predicted to be multidrug-resistant. Further spread of E. coli carrying bla NDM-5 would leave limited treatment options for serious E. coli infections.

Abstract
BackgroundCarbapenemase-producing Enterobacterales (CPE) are rapidly increasing worldwide, also in Europe. Although prevalence of CPE in Germany is comparatively low, the National Reference Centre for Multidrug-resistant Gram-negative Bacteria noted annually increasing numbers of NDM-5-producing Escherichia coli isolates.AimAs part of our ongoing surveillance programme, we characterised NDM-5-producing E. coli isolates received between 2013 and 2019 using whole genome sequencing (WGS).MethodsFrom 329 identified NDM-5-producing E. coli, 224 isolates from known geographical locations were subjected to Illumina WGS. Analyses of 222 sequenced isolates included multilocus sequence typing (MLST), core genome (cg)MLST and single-nucleotide polymorphism (SNP)-based analyses.ResultsResults of cgMLST revealed genetically distinct clusters for many of the 43 detected sequence types (ST), of which ST167, ST410, ST405 and ST361 predominated. The SNP-based phylogenetic analyses combined with geographical information identified sporadic cases of nosocomial transmission on a small spatial scale. However, we identified large clusters corresponding to clonal dissemination of ST167, ST410, ST405 and ST361 strains in consecutive years in different regions in Germany.ConclusionOccurrence of NDM-5-producing E. coli rose in Germany, which was to a large extent due to the increased prevalence of isolates belonging to the international high-risk clones ST167, ST410, ST405 and ST361. Of particular concern is the supra-regional dissemination of these epidemic clones. Available information suggest community spread of NDM-5-producing E. coli in Germany, highlighting the importance of epidemiological investigation and an integrated surveillance system in the One Health framework.

Abstract
The spread of antibiotic-resistant priority pathogens outside hospital settings is, both, a significant public health concern and an environmental problem. In recent years, New Delhi Metallo-β-lactamase (NDM)-positive strains have caused nosocomial infections with high mortality and poor prognosis worldwide. Our study investigated the links of NDM-positive strains between the hospital and the connecting river system in Jinan city, Eastern China by using NDM-producing Escherichia coli (NDM-EC) as an indicator via whole genome sequencing. Thirteen NDM-EC isolates were detected from 187 river water and sediment samples, while 9 isolates were identified from patients at the local hospital. All NDM-EC isolates were resistant to imipenem, meropenem, cefotaxime, cefoxitin, ampicillin, tetracycline, fosfomycin, piperacillin-tazobactam. The blaNDM-5 (n = 20) and blaNDM-9 (n = 2) genes were identified, which were predominantly on IncX3 plasmids (n = 13), followed by IncFII plasmids (n = 5) and IncFIA plasmids (n = 2). Conjugation experiments showed that 21 isolates could transfer NDM-harboring plasmids. The well-conserved blaNDM-5 genetic environment (ISAba125-blaNDM-5/9-bleMBL-trpF-dsbD-IS26) of these plasmids suggested a common genetic origin. Nine sequence types (STs) were detected, including three international high-risk clones ST167 (n = 8), ST410 (n = 1), and ST617 (n = 1). Phylogenetic analysis showed ST167 E. coli from the river was genotypically related to clinical isolates recovered from patients. Furthermore, ST167 isolates showed high genetic similarities with other clinical strains from geographically distinct regions. The genetic concordance between isolates from different sampling sites in the same river (ST218 clone), and different rivers (ST448 clone) raises concerns regarding the rapid dissemination of NDM-EC in the aquatic environment. The emergence and spread of the clinically relevant NDM-positive strains, especially for E. coli ST167 clone, an international high-risk clone associated with multi-resistance and virulence capacity, within and between the hospital and aquatic environments were elucidated, highlighting the need for attention and action.

Abstract
Aquatic environment can act as reservoir and disseminator of antimicrobial resistance and resistant pathogens. Novel high-risk carbapenem resistant E. coli (CREC) are continuously emerging worldwide; however, the occurrence of CREC in freshwater aquaculture environment is largely unexplored. To fill this gap, large scale sampling of freshwater pond sites and retail fish markets was done between Oct 2020 and Oct 2021 to investigate the CREC contamination in fish. The frequency of CREC contamination in the freshwater fish was 6.99% (95% CI: 3.78-10.20%). All the isolates were MDR and harbored carbapenemase encoding gene, blaNDM-5 along with other antimicrobial resistance genes (ARGs), blaTEM (64.7%), blaCTX-M-15 (35.3%), blaOXA-1 (5.9%), tet(A) (100%), sul1 (94.1%), qnrS (82.3%), cat1 (35.3%), and cat2 (23.5%). The isolates belonged to phylogroup C and showed low virulence gene profile. ERIC-PCR grouped the isolates into five clusters (I-V). The isolates of clusters I, II, and III were identified as ST167 (76.4%) and of cluster IV as ST361 (17.6%). This is the first report documenting the contamination of NDM-5 producing E. coli ST167 and ST361 of clinical/livestock lineage in freshwater fish from India. The blaNDM-5 was significantly associated with ARGs, tet(A), and sul1; and plasmid replicons, IncF, IncI1, and IncP, signifying the presence of blaNDM-5 and associated ARGs on these transferable plasmids. These findings were validated by the successful conjugal transfer of blaNDM-5 and associated ARGs into non-CREC strain (J53). Our study highlights the ability of CREC to disseminate antimicrobial resistance which has health implications and environmental concerns.

Genome stability during serial subculturing in hyperepidemic multidrug-resistant Klebsiella pneumoniae and Escherichia coli. J Glob Antimicrob Resist 2022; 31:152-161. [PMID: 36049731 DOI: 10.1016/j.jgar.2022.08.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 07/19/2022] [Accepted: 08/09/2022] [Indexed: 12/30/2022] Open
Abstract
OBJECTIVES Core-genome single nucleotide variant (cgSNV) analysis represents a powerful tool for epidemiological investigations of multidrug-resistant (MDR) bacteria. However, cgSNV thresholds to confirm whether isolates are the same clone are not formally defined. METHODS We implemented hybrid whole-genome sequencing to study the genomic changes of four MDR isolates belonging to hyperepidemic sequence types (STs) during 20 propagation steps (T20) on MacConkey and CHROMID(R) ESBL plates. The following strains were analyzed: Klebsiella pneumoniae AE-2247421 (OXA-48/NDM-1-producing, ST101), K. pneumoniae MCL-2017-2 (CTX-M-15-producing, ST307), Escherichia coli Ec-042 (OXA-181-producing, ST410), and E. coli Ec-050 (NDM-5-producing, ST167). The genome assembly at T5 and T20 was compared to that at time point zero (T0) and to two reference genomes. RESULTS At T20, AE-2247421 lost the IncL blaOXA-48-carrying plasmid when grown on CHROMID(R) ESBL plates, while a large fragment encompassing blaNDM-1 was lost from its IncC plasmid when grown on both plates. In contrast, no structural changes were noted for the other three strains. Regarding the cgSNVs, the following results were obtained at T5 and T20 (ranges considering the different agar plates and reference genomes): AE-2247421 (1-8 and 2-12 cgSNVs), MCL-2017-2 (both 1-2 cgSNVs), Ec-042 (both 0 cgSNVs), and Ec-050 (0-6 and 0-9 cgSNVs). CONCLUSION We showed that structural changes and accumulation of cgSNVs can occur in few propagation steps under laboratory conditions. These changes might also arise in the clinical context in a short time, especially under antibiotics treatment. This phenomenon should be carefully considered because it might affect the final interpretation of epidemiological genomic analyses.

Abstract
An extensively drug-resistant Escherichia coli clinical isolate (N1606) belonging to Sequence Type 361 was recovered from the urine of a patient hospitalized in Switzerland. The strain showed resistance to virtually all β-lactams including the latest generation antibiotics cefiderocol and aztreonam-avibactam. Whole genome sequencing revealed that it possessed two carbapenemase-encoding genes, namely blaNDM-5 and blaKPC-3, and a series of additional β-lactamase genes, including blaCTX-M-15 and blaSHV-11 encoding extended-spectrum β-lactamases (ESBLs), blaCMY-145 encoding an AmpC-type cephalosporinase, and blaOXA-1 encoding a narrow-spectrum class D ß-lactamase. Most of these resistance genes were located on plasmids (IncFII-FIA, IncX3, IncIγ, IncFII). That strain exhibited also a four amino-acid insertion in its penicillin-binding protein 3 (PBP3) sequence, namely corresponding to YRIN. Complete genome analysis revealed that this E. coli isolate carried virulence factors (sitA, gad, hra, terC, traT, and cia) and many other non-β-lactam resistance determinants including rmtB, tet(A), dfrA17 (two copies), aadA1, aadA5 (two copies), sul1 (two copies), qacE (two copies), qepA, mdf(A), catA1, erm(B), mph(A), and qnrS1, being susceptible only to tigecycline, colistin and fosfomycin. In conclusion, we described here the phenotypic and genome characteristics of an extensively drug-resistant (XDR) E. coli ST361 being recognized as an emerging clone worldwide.

Abstract
Carbapenem-resistant Klebsiella pneumoniae (CRKP) seriously threaten the efficacy of modern medicine with a high associated mortality rate and unprecedented transmission rate. In this study, we isolated a clinical K. pneumoniae strain DY1928 harboring blaNDM-1 from a neonate with blood infection. Antimicrobial susceptibility testing indicated that DY1928 was resistant to various antimicrobial agents, including meropenem, imipenem, ceftriaxone, cefotaxime, ceftazidime, cefepime, piperacillin-tazobactam, and amoxicillin-clavulanate. S1 nuclease-pulsed field gel electrophoresis (S1-PFGE), southern blot and conjugation experiment revealed that the blaNDM-1 gene was located on a conjugative plasmid of IncA/C2 type with a 147.9 kb length. Whole-genome sequencing showed that there was a conservative structure sequence (blaNDM-1-ble-trpF-dsbD) located downstream of the blaNDM-1 gene. Multilocus sequence typing (MLST) classified DY1928 as ST25, which was a hypervirulent K. pneumoniae type. Phylogenetic analysis of genomic data from all ST25 K. pneumoniae strains available in the NCBI database suggested that all blaNDM-1 positive strains were isolated in China and had clinical origins. A mouse bloodstream infection model was constructed to test the virulence of DY1928, and 11 K. pneumoniae strains homologous to DY1928 were isolated from the feces of infected mice. Moreover, we found that DY1928 had a tendency to flow from the blood into the intestine in mice and caused multiple organ damage. To our knowledge, this is the first study to report an infection caused by blaNDM-1-positive ST25 K. pneumoniae in the neonatal unit. Our findings indicated that stricter surveillance and more effective actions were needed to reduce the risk of disseminating such K. pneumoniae strains in clinical settings, especially in neonatal wards.

Abstract
Animal farms have become one of the most important reservoirs of carbapenem-resistant Klebsiella spp. (CRK) owing to the wide usage of veterinary antibiotics. "One Health"-studies observing animals, the environment, and humans are necessary to understand the dissemination of CRK in animal breeding areas. Based on the concept of "One-Health," 263 samples of animal feces, wastewater, well water, and human feces from 60 livestock and poultry farms in Shandong province, China were screened for CRK. Five carbapenem-resistant Klebsiella pneumoniae (CRKP) and three carbapenem-resistant Klebsiella quasipneumoniae (CRKQ) strains were isolated from animal feces, human feces, and well water. The eight strains were characterized by antimicrobial susceptibility testing, plasmid conjugation assays, whole-genome sequencing, and bioinformatics analysis. All strains carried the carbapenemase-encoding gene bla NDM-5, which was flanked by the same core genetic structure (IS5-bla NDM-5-ble MBL-trpF-dsbD-IS26-ISKox3) and was located on highly related conjugative IncX3 plasmids. The colistin resistance gene mcr-8.1 was carried by three CRKP and located on self-transmissible IncFII(K)/IncFIA(HI1) and IncFII(pKP91)/IncFIA(HI1) plasmids. The genetic context of mcr-8.1 consisted of IS903-orf-mcr-8.1-copR-baeS-dgkA-orf-IS903 in three strains. Single nucleotide polymorphism (SNP) analysis confirmed the clonal spread of CRKP carrying-bla NDM-5 and mcr-8.1 between two human workers in the same chicken farm. Additionally, the SNP analysis showed clonal expansion of CRKP and CRKQ strains from well water in different farms, and the clonal CRKP was clonally related to isolates from animal farms and a wastewater treatment plant collected in other studies in the same province. These findings suggest that CRKP and CRKQ are capable of disseminating via horizontal gene transfer and clonal expansion and may pose a significant threat to public health unless preventative measures are taken.

Abstract
IncX3 plasmids are narrow host range plasmids mostly found in Enterobacteriaceae with great conjugation ability, high stability, no fitness cost, and the ability to improve biofilm formation in their bacterial hosts. IncX3 plasmids have spread swiftly, primarily in several nations and among different species over the last 10 years. blaNDM, blaKPC, and blaOXA-181 are the carbapenemase genes carried by IncX3 plasmids. Among them, blaNDM is often located on the IncX3 plasmid, which is deemed as the primary vehicle of blaNDM transmission. Isolates harboring IncX3 plasmids are found in nations all over the world from human, animal, and environmental sources. Cointegrate plasmids related to IncX3 have recently been discovered to increase the antibiotic resistance spectrum and potentially broaden the host range of plasmids, restricting the use of antibiotics in the clinic. There are, however, few reviews based on the physiological and epidemiological properties of IncX3 plasmid, as well as studies on the plasmid itself. Hence, we conducted a retrospective literature review to summarize the characteristics of IncX3 plasmids aiming to provide a theoretical basis for controlling the global prevalence of IncX3 plasmids and directions for further research on the functions of the related genes on the IncX3 plasmid.

Abstract
A multidrug-resistant (carbapenems, aztreonam + avibactam, and cefiderocol) ST167 Escherichia coli clinical isolate recovered from a patient hospitalized in Switzerland produced NDM-35 showing ca. 10-fold increased hydrolytic activity toward cefiderocol compared to NDM-1. The isolate co-produced a CMY-type β-lactamase, exhibited a four amino-acid insertion in PBP3, and possessed a truncated iron transporter CirA protein. Our study identified an association of unrelated resistance mechanisms leading to resistance to virtually all β-lactams in a high-risk E. coli clone.

Abstract
Introduction. The New Delhi metallo-β-lactamase (NDM) variant NDM-5 was first described in 2011 in an isolate of Escherichia coli. We noted that a high proportion of isolates of E. coli positive for bla NDM carbapenemase genes submitted to the UK Health Security Agency (formerly Public Health England) between 2019 and mid-2021 carried the bla NDM-5 allele, with many co-harbouring rmtB, rendering them highly resistant to aminoglycosides as well as to most β-lactams.Hypothesis/Gap Statement. This observation suggested that a common plasmid may be circulating.Aim. To compare these isolates and describe the plasmids carrying these resistance elements.Methodology. All isolates were sequenced on an Illumina platform, with five also subjected to long-read nanopore sequencing to provide complete assemblies. The locations of bla NDM-5, rmtB and other associated genetic elements were identified. Susceptibility testing to a wide range of antibiotics was carried out on representative isolates.Results. The 34 isolates co-harbouring bla NDM-5 and rmtB were from 14 hospital groups and six different regions across England and consisted of 11 distinct sequence types. All carried IncF plasmids. Assembly of the NDM plasmids in five isolates revealed that they carried rmtB and bla NDM-5 in an IncF conjugative plasmid ranging in size from 85.5 to 161 kb. All carried a highly conserved region, previously described in E. coli plasmid pHC105-NDM, that included bla TEM-1B and rmtB followed by sequence bounded by two IS26 elements containing ΔISAba125, bla NDM-5, ble, trpF and tat followed by ISCR1 and an integron with sul1, aadA2 and dfrA12 cassettes. This arrangement has been described in isolates from other countries and continents, suggesting that such plasmids are widely distributed, at least in E. coli, with similar plasmids also found in Klebsiella pneumoniae. Tested isolates were resistant to most antibiotics except colistin, fosfomycin and tigecycline.Conclusion. These observations suggest that conjugative plasmids carrying a highly conserved resistance gene segment have become widespread in England and elsewhere. This study highlights the value of routine whole-genome sequencing in identifying genetic elements responsible for resistance dissemination.

Abstract
Shared bikes as a public transport provide convenience for short-distance travel. Whilst they also act as a potential vector for antimicrobial resistant (AR) bacteria and antimicrobial resistance genes (ARGs). However, the understanding of the whole genome sequence of AR strains and ARGs-carrying plasmids collected from shared bikes is still lacking. Here, we used the HiSeq platform to sequence and analyze 24 Escherichia coli isolated from shared bikes around Metro Stations in Beijing. The isolates from shared bikes showed 14 STs and various genotypes. Two blaNDM-5 and blaCTX-M-199-producing ST167 E. coli have 16 resistance genes, four plasmid types and show >95% of similarities in core genomes compared with the ST167 E. coli strains from different origins. The blaNDM-5- or blaCTX-M-199-carrying plasmids sequencing by Nanopore were compared to plasmids with blaNDM-5- or blaCTX-M-199 originated from humans and animals. These two ST167 E. coli show high similarities in core genomes and the plasmid profiles with strains from hospital inpatients and farm animals. Our study indicated that ST167 E. coli is retained in diverse environments and carried with various plasmids. The analysis of strains such as ST167 can provide useful information for preventing or controlling the spread of AR bacteria between animals, humans and environments.

Abstract
Carbapenems are considered last-line beta-lactams for the treatment of infections caused by multidrug-resistant Gram-negative bacteria. However, their activity is compromised by the rising prevalence of carbapenemase-producing Enterobacterales (CPE), which are especially marked in the Indian subcontinent. In Pakistan, previous reports have warned about the possible spread of CPE in the community, but data are still partial. This study was carried out to analyse the prevalence of CPE, the genetic characterisation, and phylogenetic links among the spreading CPE in the community. In this cohort study, we collected 306 rectal swabs from patients visiting Benazir Bhutto hospital, Rawalpindi. CPEs were screened by using ertapenem-supplemented MacConkey agar. Identification was performed by using conventional biochemical tests, and genomes were sequenced using Illumina chemistry. Antibiotic resistance genes, plasmid incompatibility groups, and Escherichia coli phylogroups were determined in silico. Sequence types were determined by using MLST tool. The prevalence of CPE carriage observed was 14.4% (44/306 samples). The most common carbapenemase-encoding gene was bla-NDM-5 (n = 58) followed by blaNDM-1 (n = 7), blaNDM (non-assigned variant, n = 4), blaOXA-181 (n = 3), blaOXA-232 (n = 3) and blaNDM-7 (n = 1). Most of the CPE were E. coli (55/64, 86%), and the genomic analysis revealed a pauciclonal diffusion of E. coli with ST167 (n = 14), 405 (n = 10), 940 (n = 8), 648 (n = 6) and 617 (n = 5). We obtained a second sample from 94 patients during their hospital stay in whom carriage was negative at admission and found that 7 (7.4%) acquired a CPE. Our results indicate that the prevalence of CPE carriage in the Pakistani urban community was high and driven by the dissemination of some E. coli clones, with ST167 being the most frequent. The high CPE carriage in the community poses a serious public health threat and calls for implementation of adequate preventive measures.

Abstract
We characterized plasmids carrying blaNDM-5 detected in Escherichia coli isolated from the infection site and stool sample of a Japanese patient, with no international travel history, by whole-genome sequencing (WGS). WGS was performed using MiSeq and MinlON sequencer followed by hybrid de novo assembly. blaNDM-5 was detected on IncX3 (blaNDM-5/IncX3) plasmids; pMTY18530-4_IncX3 in E. coli TUM18530 isolated from a wound above the pubis; pMTY18780-5_IncX3 and pMTY18781-1_IncX3 in E. coli TUM18780 and TUM18781, respectively, isolated from stool. These three plasmids resembled each other and pGSH8M-2-4, previously detected in E. coli isolated from a Tokyo Bay water sample. E. coli TUM18530 and TUM18780 belonged to sequence type (ST) 1011 and had only two single nucleotide polymorphisms on the core-genome, whereas TUM18781 belonged to ST2040. Three blaNDM-5/IncX3 plasmids (pMTY18530-4_IncX3, pMTY18780-5_IncX3, and pMTY18781-1_IncX3) exhibited conjugative transfer in vitro at an average frequency of 1.71 × 10-3 per donor cell. The transconjugant was resistant to only β-lactams, including carbapenem, except aztreonam. Similarity of the blaNDM-5/IncX3 plasmids isolated from our patient compared with that isolated from the Tokyo bay water sample suggested that the plasmids may have already spread throughout the Japanese community. The blaNDM-5/IncX3 plasmid exhibited potential for easy transmission to different strains in the patient's intestine.

Abstract
Incidences of nosocomial infections mediated by New Delhi metallo-β-lactamase (NDM) enzyme-producing Enterobacterales are increasing globally, resulting in a great burden to public health. The carbapenem-resistant Enterobacterales (CRE) were collected from Henan, China during 2013-2016. The blaNDM-positive strains were characterized using PCR, antimicrobial susceptibility testing, conjugation assay, S1 nuclease pulsed-field gel electrophoresis (S1-PFGE), Southern blot, whole-genome sequencing (WGS), and bioinformatics analysis. Eighty-one NDM-producing strains were identified among 391 nonduplicate CRE strains. Among them, four strains cocarried mcr and blaNDM genes, and two carried blaIMP-4 and blaNDM genes. The coexistence of blaNDM-5 and mcr-9 in Enterobacter hormaechei was found for the first time. In total, four blaNDM subtypes were identified. Among them, blaNDM-1 and blaNDM-5 were predominant. There was an obvious increasing trend in blaNDM-5 from 2013 to 2016. Thirteen different bacterial species were found among the 81 strains, and Escherichia coli was the dominant strain. blaNDM genes were located on nine different Inc-type plasmids, most of them on the IncX3 plasmids, except for the Pr-15-2-50 strain, which was located on the chromosome. We characterized two novel plasmids: the IncHI5-like plasmid carrying blaNDM-9 found in K. pneumonia, and the IncI1 blaNDM-5-positive plasmid. These findings provide the genomic basis for the widespread transmission of blaNDM and pave the way for the formulation of more effective monitoring and control methods. IMPORTANCE To control the emergence and transmission of CRE, it is important to perform retrospective genomic investigations. It is important to evaluate the plasmid diversity, genetic environment, and evolutionary relationships of the blaNDM-positive clinical strains in the early transmission stages. This study conducted an in-depth analysis of blaNDM-positive pathogens during a 4-year period using different methods for observing the high prevalence and active transmission of blaNDM-positive CRE. Moreover, we also explored the coexistence of the blaNDM and mcr, a clinically important mobile colistin resistance gene. This study shows that the prevalence of blaNDM-positive pathogens in Henan is high and the isolation rates increase each year. Moreover, plasmid-mediated horizontal transfer plays an important role in blaNDM dissemination. The co-occurrence of multiple resistance genes highlighted a long-lasting evolutionary pathway. Therefore, we have suggested the long-term continuous surveillance of clinical pathogens carrying blaNDM to learn the future transmission trend and curb the public health risk caused by CRE.

Abstract
The chicken gut microbiota, as a reservoir of antibiotic resistance genes (ARGs), poses a high risk to humans and animals worldwide. Yet a comprehensive exploration of the chicken gut antibiotic resistomes remains incomplete. In this study, we established the largest chicken gut resistance gene catalogue to date through metagenomic analysis of 629 chicken gut samples. We found significantly higher abundance of ARGs in the Chinese chicken gut than that in the Europe. tetX, mcr, and blaNDM, the genes resistant to antibiotics of last resort for human and animal health, were detected in the Chinese chicken gut. The abundance of ARGs was linearly correlated with that of mobile genetic elements (MGEs). The host-tracking analysis identified Escherichia, Enterococcus, Staphylococcus, Klebsiella, and Lactobacillus as the major ARG hosts. Especially, Lactobacillus, an intestinal probiotic, carried multiple drug resistance genes, and was proportional to ISLhe63, highlighting its potential risk in agricultural production processes. We first established a reference gene catalogue of chicken gut antibiotic resistomes. Our study helps to improve the knowledge and understanding of chicken antibiotic resistomes for knowledge-based sustainable chicken meat production. IMPORTANCE The prevalence of antibiotic resistance genes in the chicken gut environment poses a serious threat to human health; however, we lack a comprehensive exploration of antibiotic resistomes and microbiomes in the chicken gut environment. The results of this study demonstrate the diversity and abundance of antibiotic resistance genes and flora in the chicken gut environment and identify a variety of potential hosts carrying antibiotic resistance genes. Further analysis showed that mobile genetic elements were linearly correlated with antibiotic resistance genes abundance, implying that we should pay attention to the role played by mobile genetic elements in antibiotic resistance genes transmission. We established a reference genome of gut antibiotic resistance genes in chickens, which will help to rationalize the use of drugs in poultry farming.

Abstract
OBJECTIVES Carbapenems are one of the latest therapeutic choices to treat infections due to multi-drug resistant microorganisms. For this reason, the spread of carbapenemase producing Enterobacteriaceae represents a serious health public problem. In this study, we describe isolates co-producing blaNDM-5 and blaOXA-1 METHODS: Three Escherichia coli isolates obtained from patients with invasive infection were analysed by phenotypic antibiotic susceptibility and whole genome sequencing (WGS). RESULTS All the isolates were resistant to carbapenems, most beta-lactam antibiotics, piperacillin-tazobactam, amoxicillin/clavulanic acid and ciprofloxacin, remaining susceptible to amikacin, fosfomycin, colistin and tigecycline. The isolates belonged to ST-44, ST-405 and ST-167 and co-harboured the blaNDM-5 and blaOXA-1 genes. Two of them harboured also some ESBL genes (blaCTX-M-15 and blaTEM-1b). blaNDM5 gene was probably carried chromosomally even if different plasmids were identified. Different virulence genes were also identified. CONCLUSIONS Our results highlight that continuous surveillance is essential to monitor the spread of clinically important multidrug resistant pathogens.

Abstract
Carbapenemase-producing Enterobacterales (CPE) bacteria are a critical global health concern; New Delhi metallo-β-lactamase (NDM) enzymes account for >25% of all CPE found in Switzerland. We characterized NDM-positive CPE submitted to the Swiss National Reference Center for Emerging Antibiotic Resistance during a 2-year period (January 2019–December 2020) phenotypically and by using whole-genome sequencing. Most isolates were either Klebsiella pneumoniae (59/141) or Escherichia coli (52/141), and >50% were obtained from screening swabs. Among the 108 sequenced isolates, NDM-1 was the most prevalent variant, occurring in 56 isolates, mostly K. pneumoniae (34/56); the next most prevalent was NDM-5, which occurred in 49 isolates, mostly E. coli (40/49). Fourteen isolates coproduced a second carbapenemase, predominantly an OXA-48-like enzyme, and almost one third of isolates produced a 16S rRNA methylase conferring panresistance to aminoglycosides. We identified successful plasmids and global lineages as major factors contributing to the increasing prevalence of NDMs in Switzerland.

Abstract
Introduction New Delhi metallo-β-lactamase producing Klebsiella pneumoniae (NDM-Kpn) strains have been causing healthcare-associated infections worldwide. The aim of this study was to describe the molecular mechanisms of antimicrobial resistance and to analyze the clonality of NDM-Kpn isolates collected between January 2019 and June 2020 from patients admitted to hospitals from the Lazio region, Italy. Methods We performed a retrospective cohort study. Whole-genome sequencing (WGS) was performed on all NDM-Kpn strains; clonality and genetic relationships were further investigated. Results During the surveillance period, 17 NDM-Kpn isolates were obtained from 17 patients admitted to seven different hospitals. Eight different sequence types (STs) were detected: ST147 (n = 4), ST383 (n = 4), ST15 (n = 3), ST11 (n = 2), ST17 (n = 1), ST29 (n = 1), ST307 (n = 1) and the newly identified ST4853 (n = 1). Genetic relationships were further investigated by the WGS-based core genome MLST (cgMLST) scheme, and 5 cluster types (CTs) were identified. Whereas a substantial overall heterogeneity among isolates was detected (8 different STs were identified out of 17 isolates), the strains within each cluster showed a very high level of genome similarity. Discussion Our study highlights the key role of surveillance, which allowed taking a picture of a part of the NDM-Kpn strains circulating in Italy, adding further insight into their molecular features.

Abstract
Escherichia coli causing urinary tract infections (UTIs) are one of the most common outpatient bacterial infections. This study aimed to compare the characteristics of E. coli isolated from UTI patients in a single medical center in 2009-2010 (n = 504) and 2020 (n = 340). The antimicrobial susceptibility of E. coli was determined by the disk diffusion method. PCRs were conducted to detect phylogenetic groups, ST131, K1 capsule antigen, and 15 virulence factors. Phylogenetic group B2 dominated in our 2009-2010 and 2020 isolates. Moreover, no phylogenetic group E strains were isolated in 2020. E. coli isolates in 2020 were more susceptible to amoxicillin, ampicillin/sulbactam, cefuroxime, cefmetazole, ceftazidime, cefoxitin, tetracycline, and sulfamethoxazole/trimethoprim, compared to the isolates in 2009-2010. Extensively drug-resistant (XDR)-E. coli in 2009-2010 were detected in groups B1 (5 isolates), B2 (12 isolates), F (8 isolates), and unknown (1 isolate). In 2020, XDR-E. coli were only detected in groups A (2 isolates), B2 (5 isolates), D (1 isolate), and F (4 isolates). The prevalence of virulence factor genes aer and fimH were higher in E. coli in 2009-2010 compared to those in 2020. In contrast, afa and sat showed higher frequencies in E. coli isolates in 2020 compared to E. coli in 2009-2010.
