Emergence of tet(X4)-positive Enterobacterales in retail eggs and the widespread of IncFIA(HI1)-HI1A-HI1B(R27) plasmids carrying tet(X4). Int J Food Microbiol 2024; 414:110574. [PMID: 38325259 DOI: 10.1016/j.ijfoodmicro.2024.110574] [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: 09/07/2023] [Revised: 01/04/2024] [Accepted: 01/07/2024] [Indexed: 02/09/2024]
Abstract
The proliferation of antimicrobial-resistant microbes and resistance genes in various foods poses a serious hazard to public health. The plasmid-mediated tigecycline resistance gene tet(X4) has been detected in Enterobacterales from various niches but has not yet been reported in eggs. This study aimed to investigate the occurrence and characteristics of tigecycline-resistant strains from retail eggs. A total of 144 eggs were purchased from farmers' markets in Guangdong province, China, and eggshell (n = 144) and egg content (n = 96) samples were used to screen for tigecycline-resistant strains. Eight Escherichia coli strains (two ST195, one ST48, ST8165, ST752, ST93, ST189, and ST224) and one Klebsiella pneumoniae strain (ST252) recovered from eight (5.56 %, 8/144) egg samples (eggshells, n = 6; egg content, n = 2) were positive for tet(X4). Notably, the two E. coli ST195 strains were closely (15-54 SNPs) related to all the tet(X4)-positive E. coli ST195 from various origins (food animals, foods, migratory birds, human, and environment) deposited in GenBank. The E. coli ST224 showed a close phylogenetic relationship (9-12 SNPs) with two tet(X4)-positive E. coli strains from chicken feces and retail chicken in Guangdong province. The hybrid plasmid IncFIA(HI1)-HI1A-HI1B(R27) constitutes the predominant tet(X4) vector both herein (7/9, 77.78 %) and in the GenBank database (32/160, 20 %). The tet(X4)-positive IncFIA(HI1)-HI1A-HI1B(R27) plasmids, sharing highly similar structures, have been widely disseminated across China. However, the IncFIA(HI1)-HI1A-HI1B(R27) plasmids exhibit poor stability and low conjugation frequency. The contamination of tet(X4)-positive bacteria internally and externally in retail eggs poses a prospective food safety threat. More attention should be paid to the spread of the tet(X4) gene via epidemic clone E. coli ST195 and the plasmid IncFIA(HI1)-HI1A-HI1B(R27).

Abstract
The New Delhi Metallo-β-lactamase (NDM) producing Enterobacterales has been detected from diverse sources but has rarely been reported in retail eggs. In this study, 144 eggshell and 96 egg content samples were collected in 2022 from Guangdong province and were screened for NDM-producing strains. Four Escherichia coli strains (ST3014, ST10, ST1485, and ST14747) recovered from two (1.39%, 2 of 144) eggshells and two (2.08%, 2 of 96) egg content samples were identified as blaNDM-5-positive strains. Oxford Nanopore MinION sequencing and conjugation assays revealed that the blaNDM-5 gene was carried by IncX3 (n = 1), IncI1 (n = 1), and IncHI2 (n = 2). The IncI1-plasmid-carrying blaNDM-5 displayed high homology with one plasmid pEC6563-NDM5 from the human clinic, while the IncHI2 plasmid harboring blaNDM-5 shared highly similar structures with plasmids of animal origin. To the best of our knowledge, this is the first report on the identification of blaNDM-5-positive bacteria in retail eggs. NDM-producing E. coli could be transmitted to humans by the consumption of eggs or direct contact, which could pose a potential threat to human health.

Abstract
Poultry meat is one of the major animal protein sources necessary to meet the global protein demand. Sustainability in broiler production is the key to achieving its continuous supply, and broiler breeders play a critical role in maintaining this sustainability by providing good quality chicks. Colibacillosis, the disease caused by avian pathogenic Escherichia coli (APEC), causes severe economic losses to the poultry industry globally. Moreover, APEC causes an additional burden among broiler breeders, such as a decrease in egg production and mortality among these birds. There is vertical transmission of APEC to the broiler chicks through eggs, resulting in increased first-week mortality and subsequent horizontal transmission at the hatchery. In this regard, the vertical transmission of antibiotic resistance genes is another concern that needs attention. Controlling several diseases in broiler breeders would possibly reduce the first-week mortality in chicks, thereby maintaining the production level. For that, constant monitoring of the bacterial populations is critical. Moreover, amidst the increased antibiotic resistance pattern, more focus on alternative treatment strategies like vaccines, probiotics, and bacteriophages is necessary. Future research focusing on strategies to mitigate APEC in broiler breeders would be one of the finest solutions for sustainable broiler production.

Abstract
The lytic bacteriophages have potential application value in the treatment of bacterial infections. However, the narrow host spectrum of these phages limits their range of clinical application. Here, we demonstrate the use of scarless Cas9-assisted recombination (no-SCAR) gene-editing technology to regulate phage-host range. We used phage PHB20 as the scaffold to create agents targeting different multidrug-resistant Escherichia coli by replacing its phage tail fiber gene (ORF40). The engineered phages were polyvalent and capable of infecting both the original host bacteria and new targets. Phage-tail fiber genes can be amplified by PCR to construct a recombinant phage PHB20 library that can deal with multidrug-resistant bacteria in the future. Our results provide a better understanding of phage-host interactions, and we describe new anti-bacterial editing methods.

Abstract
Antimicrobial resistance is a worldwide public health threat. Farm animals are important sources of bacteria containing antimicrobial resistance genes (ARGs). Although the use of antimicrobials in aquaculture and livestock has been reduced in several countries, these compounds are still routinely applied in animal production, and contribute to ARGs emergence and spread among bacteria. ARGs are transmitted to humans mainly through the consumption of products of animal origin (PAO). Bacteria can present intrinsic resistance, and once antimicrobials are administered, this resistance may be selected and multiply. The exchange of genetic material is another mechanism used by bacteria to acquire resistance. Some of the main ARGs found in bacteria present in PAO are the bla, mcr-1, cfr and tet genes, which are directly associated to antibiotic resistance in the human clinic.

Abstract
In the last few years, antimicrobial resistant (AMR) Escherichia coli have been detected in newborn chickens suggesting their vertical transmission from breeding birds to their offspring. However, little is known about the presence of AMR E. coli in the reproductive organs of broiler breeders. The aim of this study was to investigate the presence of E. coli in the ovaries of healthy broiler breeders and to study their antimicrobial resistance. Samples from broiler breeders (n = 80) collected from 80 different broiler breeder flocks were included in this study. Antibiotic susceptibility testing was performed using disk diffusion method according to Clinical and Laboratory Standards Institute guidelines. Minimal inhibitory concentrations (MICs) of five antimicrobial agents were determined by Etest. PCR and sequencing were used to detect the blaESBL genes. E. coli were detected in the ovaries of thirty seven out of 80 (46.25%) sampled flocks. High levels of resistance to various first-line antimicrobial agents were recorded in E. coli isolates. This study showed that 89.18% of E. coli isolates were multidrug resistant (MDR). Furthermore, MDR extended-spectrum β-lactamases (ESBL)-producing E. coli were detected in the ovaries of four different broiler breeder flocks. Molecular characterization revealed that three isolates harboured blaCTX-M-1 gene and one isolate expressed blaSHV-12 gene. In addition, one blaCTX-M-1 -producing E. coli co-harboured the blaTEM-1 gene. These findings would contribute to a better epidemiological understanding of MDR E. coli for improve existing preventive strategies in order to reduce the dissemination of antimicrobial resistance in the broiler production system.
