Global transmission of extended-spectrum cephalosporin resistance in Escherichia coli driven by epidemic plasmids. EBioMedicine 2024; 103:105097. [PMID: 38608515 PMCID: PMC11024496 DOI: 10.1016/j.ebiom.2024.105097] [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: 09/07/2023] [Revised: 03/18/2024] [Accepted: 03/19/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND Extended-spectrum cephalosporins (ESCs) are third and fourth generation cephalosporin antimicrobials used in humans and animals to treat infections due to multidrug-resistant (MDR) bacteria. Resistance to ESCs (ESC-R) in Enterobacterales is predominantly due to the production of extended-spectrum β-lactamases (ESBLs) and plasmid-mediated AmpC β-lactamases (AmpCs). The dynamics of ESBLs and AmpCs are changing across countries and host species, the result of global transmission of ESC-R genes. Plasmids are known to play a key role in this dissemination, but the relative importance of different types of plasmids is not fully understood. METHODS In this study, Escherichia coli with the major ESC-R genes blaCTX-M-1, blaCTX-M-15, blaCTX-M-14 (ESBLs) and blaCMY-2 (AmpC), were selected from diverse host species and other sources across Canada, France and Germany, collected between 2003 and 2017. To examine in detail the vehicles of transmission of the ESC-R genes, long- and short-read sequences were generated to obtain complete contiguous chromosome and plasmid sequences (n = 192 ESC-R E. coli). The types, gene composition and genetic relatedness of these plasmids were investigated, along with association with isolate year, source and geographical origin, and put in context with publicly available plasmid sequences. FINDINGS We identified five epidemic resistance plasmid subtypes with distinct genetic properties that are associated with the global dissemination of ESC-R genes across multiple E. coli lineages and host species. The IncI1 pST3 blaCTX-M-1 plasmid subtype was found in more diverse sources than the other main plasmid subtypes, whereas IncI1 pST12 blaCMY-2 was more frequent in Canadian and German human and chicken isolates. Clonal expansion also contributed to the dissemination of the IncI1 pST12 blaCMY-2 plasmid in ST131 and ST117 E. coli harbouring this plasmid. The IncI1 pST2 blaCMY-2 subtype was predominant in isolates from humans in France, while the IncF F31:A4:B1 blaCTX-M-15 and F2:A-:B- blaCTX-M-14 plasmid subtypes were frequent in human and cattle isolates across multiple countries. Beyond their epidemic nature with respect to ESC-R genes, in our collection almost all IncI1 pST3 blaCTX-M-1 and IncF F31:A4:B1 blaCTX-M-15 epidemic plasmids also carried multiple antimicrobial resistance (AMR) genes conferring resistance to other antimicrobial classes. Finally, we found genetic signatures in the regions surrounding specific ESC-R genes, identifying the predominant mechanisms of ESC-R gene movement, and using publicly available databases, we identified these epidemic plasmids from widespread bacterial species, host species, countries and continents. INTERPRETATION We provide evidence that epidemic resistance plasmid subtypes contribute to the global dissemination of ESC-R genes, and in addition, some of these epidemic plasmids confer resistance to multiple other antimicrobial classes. The success of these plasmids suggests that they may have a fitness advantage over other plasmid types and subtypes. Identification and understanding of the vehicles of AMR transmission are crucial to develop and target strategies and interventions to reduce the spread of AMR.

Antimicrobial resistance, β-lactamase genotypes, and plasmid replicon types of Shiga toxin-producing Escherichia coli isolated from different animal hosts. J Appl Microbiol 2024; 135:lxae059. [PMID: 38467395 DOI: 10.1093/jambio/lxae059] [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: 01/16/2024] [Revised: 02/11/2024] [Accepted: 03/10/2024] [Indexed: 03/13/2024]
Abstract
AIMS The primary objective of this study was to analyze antimicrobial resistance (AMR), with a particular focus on β-lactamase genotypes and plasmid replicon types of Shiga toxin-producing Escherichia coli (STEC) strains originating from various animal hosts. METHODS AND RESULTS A total of 84 STEC strains were isolated from cattle (n = 32), sheep/goats (n = 26), pigeons (n = 20), and wild animals (n = 6) between 2010 and 2018 in various regions of Iran. The Kirby-Bauer susceptibility test and multiple polymerase chain reaction (PCR) panels were employed to elucidate the correlation between AMR and plasmid replicon types in STEC isolates. The predominant replicon types were IncFIC and IncFIB in cattle (46.8%), IncFIC in sheep/goats (46.1%), IncA/C in pigeons (90%), and IncP in wild animals (50%). STEC of serogroups O113, O26, and O111 harbored the IncFIB (100%), IncI1 (80%), and IncFIC + IncA/C (100%) plasmids, respectively. A remarkable AMR association was found between ciprofloxacin (100%), neomycin (68.7%), and tetracycline (61.7%) resistance with IncFIC; amoxicillin + clavulanic acid (88.8%) and tetracycline (61.7%) with IncA/C; ciprofloxacin (100%) with IncFIB; fosfomycin (85.7%) and sulfamethoxazole + trimethoprim (80%) with IncI1. IncI1 appeared in 83.3%, 50%, and 100% of the isolates harboring blaCTX-M, blaTEM, and blaOXA β-lactamase genes, respectively. CONCLUSIONS The emergence of O26/IncI1/blaCTX-M STEC in cattle farms poses a potential risk to public health.

Antimicrobial Resistance in Escherichia coli from the Broiler Farm Environment, with Detection of SHV-12-Producing Isolates. Antibiotics (Basel) 2022; 11:antibiotics11040444. [PMID: 35453196 PMCID: PMC9024766 DOI: 10.3390/antibiotics11040444] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 03/19/2022] [Accepted: 03/23/2022] [Indexed: 02/06/2023] Open
Abstract
Antimicrobial resistance is an important One Health challenge that encompasses the human, animal, and environmental fields. A total of 111 Escherichia coli isolates previously recovered from manure (n = 57) and indoor air (n = 54) samples from a broiler farm were analyzed to determine their phenotypes and genotypes of antimicrobial resistance and integron characterization; in addition, plasmid replicon analysis and molecular typing were performed in extended-spectrum-beta-lactamase (ESBL) producer isolates. A multidrug-resistance phenotype was detected in 46.8% of the isolates, and the highest rates of resistance were found for ampicillin, trimethoprim−sulfamethoxazole, and tetracycline (>40%); moreover, 15 isolates (13.5%) showed susceptibility to all tested antibiotics. None of the isolates showed imipenem and/or cefoxitin resistance. Twenty-three of the one hundred and eleven E. coli isolates (20.7%) were ESBL producers and carried the blaSHV-12 gene; one of these isolates was recovered from the air, and the remaining 22 were from manure samples. Most of ESBL-positive isolates carried the cmlA (n = 23), tet(A) (n = 19), and aac(6′)-Ib-cr (n = 11) genes. The following genetic lineages were identified among the ESBL-producing isolates (sequence type-phylogroup-clonotype): ST770-E-CH116−552 (n = 12), ST117-B2-CH45−97 (n = 4), ST68-E-CH26−382/49 (n = 3), ST68-E-CH26−49 (n = 1), and ST10992-A/B1-CH11−23/41/580 (n = 4); the latter two were detected for the first time in the poultry sector. At least two plasmid replicon types were detected in the ESBL-producing E. coli isolates, with IncF, IncF1B, IncK, and IncHI1 being the most frequently found. The following antimicrobial resistance genes were identified among the non-ESBL-producing isolates (number of isolates): blaTEM (58), aac(6′)-Ib-cr (6), qnrS (2), aac(3)-II (2), cmlA (6), tet(A)/tet(B) (22), and sul1/2/3 (51). Four different gene-cassette arrays were detected in the variable region of class 1 (dfrA1-aadA1, dfrA12-aadA2, and dfrA12-orf-aadA2-cmlA) and class 2 integrons (sat2-aadA1-orfX). This work reveals the worrying presence of antimicrobial-resistant E. coli in the broiler farm environment, with ESBL-producing isolates of SHV-12 type being extensively disseminated.
