Genomic insights into ESBL-producing Escherichia coli isolated from non-human primates in the Peruvian Amazon. Front Vet Sci 2024; 10:1340428. [PMID: 38292135 PMCID: PMC10825005 DOI: 10.3389/fvets.2023.1340428] [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: 11/17/2023] [Accepted: 12/29/2023] [Indexed: 02/01/2024] Open
Abstract
Introduction Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae are on the WHO priority pathogens list because they are associated with high mortality, health-care burden, and antimicrobial resistance (AMR), a serious problem that threatens global public health and should be addressed through the One Health approach. Non-human primates (NHP) have a high risk of acquiring these antibiotic-resistant bacteria due to their close phylogenetic relationship with humans and increased anthropogenic activities in their natural environments. This study aimed to detect and analyze the genomes of ESBL-producing Escherichia coli (ESBL-producing E. coli) in NHP from the Peruvian Amazon. Materials and methods We collected a total of 119 fecal samples from semi-captive Saguinus labiatus, Saguinus mystax, and Saimiri boliviensis, and captive Ateles chamek, Cebus unicolor, Lagothrix lagothricha, and Sapajus apella in the Loreto and Ucayali regions, respectively. Subsequently, we isolated and identified E. coli strains by microbiological methods, detected ESBL-producing E. coli through antimicrobial susceptibility tests following CLSI guidelines, and analyzed their genomes using previously described genomic methods. Results We detected that 7.07% (7/99) of E. coli strains: 5.45% (3/55) from Loreto and 9.09% (4/44) from Ucayali, expressed ESBL phenotype. Genomic analysis revealed the presence of high-risk pandemic clones, such as ST10 and ST117, carrying a broad resistome to relevant antibiotics, including three blaCTX-M variants: blaCTX-M-15, blaCTX-M-55, and blaCTX-M-65. Phylogenomic analysis confirmed the clonal relatedness of high-risk lineages circulating at the human-NHP interface. Additionally, two ESBL-producing E. coli strains were identified as EPEC (eae) and ExPEC according to their virulence profiles, and one more presented a hypermucoviscous phenotype. Discussion We report the detection and genomic analysis of seven ESBL-producing E. coli strains carrying broad resistome and virulence factors in NHP from two regions of the Peruvian Amazon. Some of these strains are closely related to high-risk pandemic lineages previously reported in humans and domestic animals, highlighting the negative impact of anthropogenic activities on Amazonian wildlife. To our knowledge, this is the first documentation of ESBL-producing E. coli in NHP from the Amazon, underscoring the importance of adopting the One Health approach to AMR surveillance and minimizing the potential transmission risk of antibiotic-resistant bacteria at the human-NHP interface.

Detection and analysis of Shiga toxin producing and enteropathogenic Escherichia coli in cattle from Tierra del Fuego, Argentina. Braz J Microbiol 2023; 54:1257-1266. [PMID: 37041346 PMCID: PMC10235289 DOI: 10.1007/s42770-023-00958-8] [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: 12/06/2022] [Accepted: 03/22/2023] [Indexed: 04/13/2023] Open
Abstract
Shiga toxin producing Escherichia coli (STEC) and enteropathogenic E. coli (EPEC) are pathovars that affect mainly infants' health. Cattle are the main reservoir of STEC. Uremic hemolytic syndrome and diarrheas can be found at high rates in Tierra del Fuego (TDF). This study aimed to establish the prevalence of STEC and EPEC in cattle at slaughterhouses in TDF and to analyze the isolated strains. Out of 194 samples from two slaughterhouses, STEC prevalence was 15%, and EPEC prevalence was 5%. Twenty-seven STEC strains and one EPEC were isolated. The most prevalent STEC serotypes were O185:H19 (7), O185:H7 (6), and O178:H19 (5). There were no STEC eae + strains (AE-STEC) or serogroup O157 detected in this study. The prevalent genotype was stx2c (10/27) followed by stx1a/stx2hb (4/27). Fourteen percent of the strains presented at least one stx non-typeable subtype (4/27). Shiga toxin production was detected in 25/27 STEC strains. The prevalent module for the Locus of Adhesion and Autoaggregation (LAA) island was module III (7/27). EPEC strain was categorized as atypical and with the ability to cause A/E lesion. The ehxA gene was present in 16/28 strains, 12 of which were capable of producing hemolysis. No hybrid strains were detected in this work. Antimicrobial susceptibility tests showed that all strains were resistant to ampicillin and 20/28 were resistant to aminoglycosides. No statistical differences could be seen in the detection of STEC or EPEC either by slaughterhouse location or by production system (extensive grass or feedlot). The rate of STEC detection was lower than the one reported for the rest of Argentina. STEC/EPEC relation was 3 to 1. This is the first study on cattle from TDF as reservoir for strains that are potentially pathogenic to humans.

Genetic and phylogenetic characterization of Shiga toxin-producing Escherichia coli and enteropathogenic E. coli from livestock in Jiangsu by using whole-genome sequencing. J Appl Microbiol 2022; 132:3925-3936. [PMID: 35174586 DOI: 10.1111/jam.15494] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 01/19/2022] [Accepted: 02/12/2022] [Indexed: 11/29/2022]
Abstract
AIMS There are knowledge gaps regarding STEC and EPEC strains in livestock in Jiangsu, China. This study aimed to evaluate the potential public health significance of STEC and EPEC strains isolated from livestock by determining the serotypes, virulence profiles, and genetic relationship with international STEC strains. METHODS AND RESULTS A total of 68 STEC and 37 EPEC strains were obtained from 231 fecal sheep samples and 70 fecal cattle samples. By using whole-genome sequencing (WGS) analysis, all STEC belonged to 15 O:H serotypes and the most prevalent serotypes were O6:H10 (19.1%), O155:H21 (14.7%), and O21:H25 (10.3%). The main Shiga toxin gene subtypes detected were stx1c (41.2%), stx1a (26.5%), stx2b (14.7%) and stx2k (14.7%). Only the STEC from cattle carried eae gene. Other adherence-associated or toxin-related genes, including lpfA (70.6%), iha (48.5%), subA (54.4%), and ehxA (33.8%), were found in STEC. All EPEC strains were bfpA-negative, and the predominant eae variants were eae-β1 (62.2%), eae-ζ (21.6%), and eae-θ (8.1%). The core-genome multi-locus sequence typing (cgMLST) analysis revealed nine scattered clusters in STEC and one dominant cluster in EPEC. The strains with the same serotypes, including O22:H8 and O43:H2 in the two towns, possessed a closely genomic distance. The core genome single nucleotide polymorphism (cgSNP) showed that part of STEC strains in this study were clustered with isolates possessing the same serotypes from the Netherlands, Sweden, and Xinjiang of China. Five serotypes of STEC isolates were associated with the clinical STEC strains from databases. CONCLUSION This study provided the diverse serotypes and the virulence genes profiles in STEC and EPEC strains. Local strains possessed widely diverse and scattered clusters by cgMLST. Closely genomic correlation with clinical isolates displayed that part of the STEC strains may threaten to public health. SIGNIFICANCE AND IMPACT OF THE STUDY Non-O157 STEC strains act as important pathogens for human infections. This study supports the increased surveillance work of non-O157 STEC rather than just O157 STEC in this region.

Prevalence, Antimicrobial Resistance, and Whole Genome Sequencing Analysis of Shiga Toxin-Producing Escherichia coli (STEC) and Enteropathogenic Escherichia coli (EPEC) from Imported Foods in China during 2015–2021. Toxins (Basel) 2022; 14:toxins14020068. [PMID: 35202096 PMCID: PMC8875648 DOI: 10.3390/toxins14020068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 01/13/2022] [Accepted: 01/17/2022] [Indexed: 11/24/2022] Open
Abstract
Shiga toxin-producing Escherichia coli (STEC) and enteropathogenic Escherichia coli (EPEC) are foodborne pathogens that cause hemolytic uremic syndrome and fatal infant diarrhea, respectively, but the characterization of these bacteria from imported food in China are unknown. A total of 1577 food samples from various countries during 2015–2021 were screened for STEC and EPEC, and the obtained isolates were tested for antimicrobial resistance and whole genome sequencing analysis was performed. The prevalence of STEC and EPEC was 1.01% (16/1577) and 0.51% (8/1577), respectively. Antimicrobial resistances to tetracycline (8%), chloramphenicol (8%), ampicillin (4%), ceftazidime (4%), cefotaxime (4%), and trimethoprim-sulfamethoxazole (4%) were observed. The antimicrobial resistance phenotypes corresponded with genotypes for most strains, and some resistance genes were related to mobile genetic elements. All 16 STEC isolates were eae negative, two solely contained stx1 (stx1a or stx1c), 12 merely carried stx2 (stx2a, stx2d, or stx2e), and two had both stx1 and stx2 (stx1c + stx2b, stx1a + stx2a + stx2c). Although they were eae negative, several STEC isolates carried other adherence factors, such as iha (5/16), sab (1/16), and lpfA (8/16), and belonged to serotypes (O130:H11, O8:H19, and O100:H30) or STs (ST297, ST360), which have caused human infections. All the eight EPEC isolates were atypical EPEC; six serotypes and seven STs were found, and clinically relevant EPEC serotypes O26:H11, O103:H2, and O145:H28 were identified. Two STEC/ETEC (enterotoxigenic E. coli) hybrids and one EPEC/ETEC hybrid were observed, since they harbored sta1 and/or stb. The results revealed that food can act as a reservoir of STEC/EPEC with pathogenic potential, and had the potential ability to transfer antibiotic resistance and virulence genes.

The first evaluation relationship of integron genes and the multidrug-resistance in class A ESBLs genes in enteropathogenic Escherichia coli strains isolated from children with diarrhea in Southwestern Iran. Mol Biol Rep 2020; 48:307-313.

Abstract
Enteropathogenic Escherichia coli (EPEC) is one of the most important diarrheagenic agents among infants under 5 years in developing countries. This study aimed to investigate the relationship of integron genes and class A extended-spectrum ESBLs genes in MDR E. coli strains isolated from children with diarrhea in Southwestern Iran. Totally, 321 fecal samples were collected from diarrheal children under 5 years admitted to teaching hospitals of Abadan and Khorramshahr, southwest Iran. Routine bacteriological tests were performed for the identification of E. coli isolates. Multiplex PCR was used for the presence of eae, bfp, stx1, and stx2 genes to detected EPEC strains. Serogrouping was performed for EPEC strains. The EPEC isolates' antibiotic resistance pattern was determined by the disk-diffusion technique. All EPEC isolates were screened for integron and class A β-lactamase genes. Of the 14 EPEC isolates, 12 (85.7%) were found to be ESBL-positive by double disk synergy test (DDST) and PCR. In addition, blaCTX-M and blaTEM genes were detected in 83.3% (n = 10) and 58.3% (n = 7) of EPEC isolates, respectively. None of the isolates had the blaKPC gene. On the other hand, 64.2% (n = 9) and 7.1% (n = 1) were positive only for intlI and intlII genes, respectively. The results demonstrated that EPEC is one of the major causes of childhood diarrhea in our region and that the distribution of class 1 integrons and ESBLs in EPEC strains is highly prevalent. Moreover, the results revealed that continuous monitoring of the emergence and expansion of MDR in EPEC strains is necessary.

Abstract
This study investigated the antipathogenic activity and probiotic potential of indigenous lactic acid bacteria (LAB) isolated from Chinese homemade pickles. In total, 27 samples were collected from different sites in China. Fifty-nine yielded pure colonies were identified by 16S rRNA gene sequencing as LAB and were initially evaluated for the antibacterial activity in vitro. Initial screening yielded Lactobacillus plantarum GS083, GS086, and GS090, which showed a broad-spectrum antibacterial activity against food-borne pathogens, especially multidrug-resistant pathogens. Meanwhile, organic acids were mainly responsible for the antimicrobial activity of the LAB strains, and the most abundant of these was lactic acid (19.32 ± 0.95 to 24.79 ± 0.40 g/l). Additionally, three L. plantarum strains demonstrated several basic probiotic characteristics including cell surface hydrophobicity, autoaggregation, and survival under gastrointestinal (GI) tract conditions. The safety of these isolates was also evaluated based on their antibiotic susceptibility, hemolytic risk, bile salt hydrolase activity, and existence of virulence or antibiotic resistance genes. All strains were safe at both the genomic and phenotypic levels. Therefore, L. plantarum GS083, GS086, and GS090 are fairly promising probiotic candidates and may be favorable for use as preservatives in the food industry.

Abstract
Different surveillance studies (2005–2015) in northwest Spain revealed the presence of eae-positive isolates of Escherichia coli O153:H10 in meat for human consumption, poultry farm, wildlife and human diarrheagenic samples. The aim of this study was to explore the genetic and genomic relatedness between human and animal/meat isolates, as well as the mechanism of its persistence. We also wanted to know whether it was a geographically restricted lineage, or whether it was also reported elsewhere. Conventional typing showed that 32 isolates were O153:H10-A-ST10 fimH54, fimAvMT78, traT and eae-beta1. Amongst these, 21 were CTX-M-32 or SHV-12 producers. The PFGE XbaI-macrorestriction comparison showed high similarity (>85%). The plasmidome analysis revealed a stable combination of IncF (F2:A-:B-), IncI1 (STunknown) and IncX1 plasmid types, together with non-conjugative Col-like plasmids. The core genome investigation based on the cgMLST scheme from EnteroBase proved close relatedness between isolates of human and animal origin. Our results demonstrate that a hybrid MDR aEPEC/ExPEC of the clonal group O153:H10-A-ST10 (CH11-54) is circulating in our region within different hosts, including wildlife. It seems implicated in human diarrhea via meat transmission, and in the spreading of ESBL genes (mainly of CTX-M-32 type). We found genomic evidence of a related hybrid aEPEC/ExPEC in at least one other country.

Abstract
Foodborne safety has become a global public health problem in both developed and developing countries. The rapid and precise monitoring and detection of foodborne pathogens has generated a strong interest by researchers in order to control and prevent human foodborne infections. Traditional methods for the detection of foodborne pathogens are often time-consuming, laborious, expensive, and unable to satisfy the demands of rapid food testing. Owing to the advantages of simplicity, real-time analysis, high sensitivity, miniaturization, rapid detection time, and low cost, electrochemical biosensing technology is more and more widely used in determination of foodborne pathogens. Here, we summarize recent developments in electrochemical biosensing technologies used to detect common foodborne pathogens. Additionally, we discuss research challenges and future prospects for this field of study.
