Abstract
Escherichia coli belonging to multilocus sequence type 38 (ST38) is a well-known cause of extra-intestinal infections in humans, and are frequently associated with resistance to extended-spectrum cephalosporins (ESCs). Resistance to carbapenems, mediated by blaOXA-genes has also been reported in this ST. Recently, the European Centre for Disease Prevention and Control (ECDC) released a rapid risk assessment on the increased detection of OXA-244 producing E. coli ST38 in humans, requesting further knowledge to determine the source. ST38 is also one of the most common STs among ESC-resistant E. coli from broiler production. Our aim was to investigate the genetic characteristics and relationship between E. coli ST38 from broiler production and humans, and to investigate if there has been a potential spillover between these sources. A total of 288 E. coli ST38 genomes isolated from humans in Europe (collected 2009-2019) and from Nordic broiler production (collected 2011-2014) were analyzed. The results showed distinct monophyletic clades associated to humans and broiler production. Furthermore, there were differences in the ESC resistance genes present in E. coli ST38 from the two sources. The blaOXA-244 gene was not present in E. coli from broiler production. Our results show that ST38 from humans and broiler production belong to well-separated clades, and suggest that the increased detection of OXA-244-producing E. coli ST38 in humans is not associated with spillover from broiler production.

Ekhlas D, Sanjuán JMO, Manzanilla EG, Leonard FC, Argüello H, Burgess CM. Comparison of antimicrobial resistant Escherichia coli isolated from Irish commercial pig farms with and without zinc oxide and antimicrobial usage. Gut Pathog 2023; 15:8. [PMID: 36829209 PMCID: PMC9951511 DOI: 10.1186/s13099-023-00534-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 02/09/2023] [Indexed: 02/26/2023] Open
Abstract
BACKGROUND The prophylactic use of antimicrobials and zinc oxide (ZnO) in pig production was prohibited by the European Union in 2022 due to potential associations between antimicrobial and heavy metal usage with antimicrobial resistance (AMR) and concerns regarding environmental pollution. However, the effects of their usage on the bacterial AMR profiles on commercial pig farms are still not fully understood and previous studies examining the effect of ZnO have reported contrasting findings. The objective of this study was to examine the effects of antimicrobial and ZnO usage on AMR on commercial pig farms. Faecal and environmental samples were taken on 10 Irish commercial farms, of which 5 farms regularly used ZnO and antimicrobials (amoxicillin or sulphadiazine-trimethoprim) for the prevention of disease. The other 5 farms did not use ZnO or any other form of prophylaxis. Escherichia coli numbers were quantified from all samples using non-supplemented and supplemented Tryptone Bile X-glucuronide agar. RESULTS In total 351 isolates were phenotypically analysed, and the genomes of 44 AmpC/ESBL-producing E. coli isolates from 4 farms were characterised using whole-genome sequencing. Phenotypic analysis suggested higher numbers of multi-drug resistant (MDR) E. coli isolates on farms using prophylaxis. Furthermore, farms using prophylaxis were associated with higher numbers of isolates resistant to apramycin, trimethoprim, tetracycline, streptomycin, and chloramphenicol, while resistance to ciprofloxacin was more associated with farms not using any prophylaxis. Thirty-four of the 44 AmpC/ESBL-producing E. coli strains harboured the blaCTX-M-1 resistance gene and were multi drug resistant (MDR). Moreover, network analysis of plasmids and analysis of integrons showed that antimicrobial and biocide resistance genes were frequently co-located on mobile genetic elements, indicating the possibility for co-selection during antimicrobial or biocide usage as a contributor to AMR occurrence and persistence on farms. CONCLUSIONS The results of this study showed evidence that antimicrobial and ZnO treatment of pigs post-weaning can favour the selection and development of AMR and MDR E. coli. Co-location of resistance genes on mobile genetic elements was observed. This study demonstrated the usefulness of phenotypic and genotypic detection of antimicrobial resistance by combining sequencing and microbiological methods.

Front Microbiol 2022; 13:882422.

Abstract
Extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) have been classified in the group of resistant bacteria of highest priority. We determined the prevalence of ESBL-E collected in feces from household and shelter pets in Guadeloupe (French West Indies). A single rectal swab was taken from 125 dogs and 60 cats between June and September 2019. The prevalence of fecal carriage of ESBL-E was 7.6% (14/185, 95% CI: 4.2-12.4), within the range observed worldwide. The only risk factor associated with a higher prevalence of ESBL-E rectal carriage was a stay in a shelter, suggesting that refuges could be hotspots for their acquisition. All but one (Klebsiella pneumoniae from a cat) were Escherichia coli. We noted the presence of a bla CTX-M-1/IncI1-Iγ/sequence type (ST3) plasmid in 11 ESBL-producing E. coli isolates belonging to ST328 (n = 6), ST155 (n = 4) and ST953 (n = 1). A bla CTX-M-15 gene was identified in the three remaining ESBL-E isolates. The bla CTX-M-1 and most of the antimicrobial resistance genes were present in a well-conserved large conjugative IncI1-Iγ/ST3 plasmid characterized by two accessory regions containing antibiotic resistance genes. The plasmid has been detected worldwide in E. coli isolates from humans and several animal species, such as food-producing animals, wild birds and pets, and from the environment. This study shows the potential role of pets as a reservoir of antimicrobial-resistant bacteria or genes for humans and underlines the importance of basic hygiene measures by owners of companion animals.

Longitudinal Sampling Reveals Persistence of and Genetic Diversity in Extended-Spectrum Cephalosporin-Resistant Escherichia coli From Norwegian Broiler Production. Front Microbiol 2021; 12:795127.

Abstract
There are knowledge gaps concerning dynamics of extended-spectrum cephalosporin (ESC)-resistant Escherichia coli and their plasmids in broiler production and the persistence of strains on broiler farms. Thus, we aimed at characterising ESC-resistant Escherichia coli collected from all flocks reared on 10 different farms during a six-months sampling period. All isolates (n = 43) were subjected to whole-genome sequencing, and a subset of isolates (n = 7) were also sequenced using oxford nanopore technology and subsequent hybrid assembly in order to do in-depth characterisation of the ESC resistance plasmids. The 43 isolates belonged to 11 different sequence types, and three different ESC resistance gene/plasmid combinations were present, namely, IncK2/blaCMY-2 (n = 29), IncI1/blaCMY-2 (n = 6) and IncI1/blaCTX-M-1 (n = 8). ESC-resistant E. coli of different STs and with different ESC resistance gene/plasmid combinations could be present on the same farm, while a single ST and ESC resistance gene/plasmid displaying zero or few SNP differences were present on other farms. In-depth characterisation of IncK2/blaCMY-2 plasmids revealed that at least two distinct variants circulate in the broiler production. These plasmids showed close homology to previously published plasmids from other countries. Our longitudinal study show that ESC-resistant E. coli belong to a multitude of different STs and that different ESC resistance genes and plasmids occur. However, there is also indication of persistence of both ESC-resistant E. coli strains and IncK2/blaCMY-2 plasmids on farms. Further studies are warranted to determine the dynamics of strains, plasmids and ESC resistance genes within single broiler flocks.

Abstract
OBJECTIVES We aimed to elucidate the relationship among blaCTX-M-carrying plasmids and their transmission between humans and domestic animals. METHODS Phylogenetic relationship of 90 I1 plasmids harboring blaCTX-M genes encoding extended-spectrum β-lactamase (ESBL) was analyzed using the ORF-based binarized structure network analysis of plasmids (OSNAp). RESULTS The majority of plasmids carrying blaCTX-M-1 or blaCTX-M-8 belonged to a single lineage, respectively, and were primarily associated with domestic animals especially chickens. On the other hand, plasmids carrying blaCTX-M-14 or blaCTX-M-15, identified from both humans and domestic animals, were distributed in two or more lineages. CONCLUSION OSNAp has revealed the phylogenetic relationships and diversity of plasmids carrying blaCTX-M more distinctly than pMLST. The findings suggest that circulation of I1 plasmids between humans and animals may contribute to their diversity.

Abstract
The role of food-producing environments in the emergence and spread of antimicrobial resistance (AMR) in EU plant-based food production, terrestrial animals (poultry, cattle and pigs) and aquaculture was assessed. Among the various sources and transmission routes identified, fertilisers of faecal origin, irrigation and surface water for plant-based food and water for aquaculture were considered of major importance. For terrestrial animal production, potential sources consist of feed, humans, water, air/dust, soil, wildlife, rodents, arthropods and equipment. Among those, evidence was found for introduction with feed and humans, for the other sources, the importance could not be assessed. Several ARB of highest priority for public health, such as carbapenem or extended-spectrum cephalosporin and/or fluoroquinolone-resistant Enterobacterales (including Salmonella enterica), fluoroquinolone-resistant Campylobacter spp., methicillin-resistant Staphylococcus aureus and glycopeptide-resistant Enterococcus faecium and E. faecalis were identified. Among highest priority ARGs bla CTX -M, bla VIM, bla NDM, bla OXA -48-like, bla OXA -23, mcr, armA, vanA, cfr and optrA were reported. These highest priority bacteria and genes were identified in different sources, at primary and post-harvest level, particularly faeces/manure, soil and water. For all sectors, reducing the occurrence of faecal microbial contamination of fertilisers, water, feed and the production environment and minimising persistence/recycling of ARB within animal production facilities is a priority. Proper implementation of good hygiene practices, biosecurity and food safety management systems is very important. Potential AMR-specific interventions are in the early stages of development. Many data gaps relating to sources and relevance of transmission routes, diversity of ARB and ARGs, effectiveness of mitigation measures were identified. Representative epidemiological and attribution studies on AMR and its effective control in food production environments at EU level, linked to One Health and environmental initiatives, are urgently required.

Interference of ISEcp1-bla CTX-M-1 with the shufflon rearrangement in IncI1 plasmids. Plasmid 2021; 116:102578.

Abstract
IncI1 plasmids are known disseminators of the extended-spectrum cephalosporin resistance (ESC) gene blaCTX-M-1, among species of the Enterobacteriaceae family. In several IncI1 plasmids, this gene was found incorporated into the transposition unit, ISEcp1-blaCTX-M-1-orf477, interrupting a shufflon region, a hallmark of IncI1 conjugative plasmids. The shufflon diversifies pilV gene that encodes the adhesine-type protein found on the tip of the conjugative pilus. To further elucidate the shufflon rearrangement, we examined to what extent the shufflon rearrangement was affected by the transposition-unit insertion. As expected, the interrupted shufflons generated a lower number of shufflon variants and exhibited an altered segment-deletion pattern compared to the non-interrupted shufflon. Interestingly, segment-loss frequency of the interrupted shufflons was distinctive in different plasmid hosts. Finally, the analysis of the 3' end of the pilV gene revealed that shufflon rearrangement favoured segment A to complete pilV partial open reading frame regardless of the shufflon. Thereby, it could be assumed that the A-segment has greater importance during conjugation, however, this remained a hypothesis. Further exploration of shufflon rearrangement and its importance in the plasmid-recipient selection during conjugation would be beneficial as the knowledge could be applied in developing a strategy to limit IncI1 mediated antimicrobial resistance dissemination.
