Jamali H, Akrami F, Bouakkaz S, Dozois CM. Prevalence of specific serogroups, antibiotic resistance and virulence factors of avian pathogenic Escherichia coli (APEC) isolated from clinical cases: A systematic review and meta-analysis. Microb Pathog 2024; 194:106843. [PMID: 39117015 DOI: 10.1016/j.micpath.2024.106843] [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: 06/06/2024] [Revised: 07/22/2024] [Accepted: 08/05/2024] [Indexed: 08/10/2024]
Abstract
Pathogenic strains of Escherichia coli infecting poultry, commonly called avian pathogenic E. coli (APEC) present significant risks, to the health of both poultry and the general public. This systematic review aimed to examine the prevalence of APEC serotypes, sequence types (ST), phylogenetic groups, virulence factors and antibiotic resistance patterns based on 189 research papers sourced from PubMed, Web of Science, and ProQuest. Then, data were extracted from the selected studies and analyzed to assess the global distribution and characteristics of APEC strains. The metaprop codes in the Meta and Metafor packages of R as implemented in RStudio were then used to conduct meta-analysis. Among APEC strains identified from these different research reports serogroup O78 had the highest overall prevalence (16 %), followed by serogroups O2 (10 %), and O117 (8 %). The most common ST profiles were ST117 (20 %), ST140 (15 %), ST95 (12 %), and ST131 (9 %). ST117 and ST140 are known reservoirs for pathogenic E. coli in humans. Moreover, phylogenetic assessment highlighted the prevalence of phylogroups A, A1, F, D, and B2 among APEC strains indicating diversity in phylogenetic origin within poultry populations. The presence of antimicrobial resistance was notable among APEC strains against antibiotics such as tetracyclines, penicillins, and cephalosporins. This resistance may be linked to use of antimicrobials in poultry production in certain regions presenting challenges for both animal health management and human infection control. Analysis of sequences linked to adherence or virulence indicated that genes encoding adhesins (csg, fimC), iron/metal uptake (sitB, sitC, iroD) and cytotoxicity (estB, hlyF), and serum resistance (traT, iss) were highly prevalent. These factors have been reported to contribute to APEC host colonization and virulence in poultry. In summary, this overview of the characteristics of APEC highlights the pressing importance of monitoring and implementing management approaches to reduce antimicrobial resistance considering that a phylogenetic diversity of E. coli strains causes infections in both poultry and humans and represents a risk to both animal and public health. Further, determining the major conserved aspects and predominant mechanisms of virulence of APEC is critical for improving diagnostics and developing preventative measures to reduce the burden of infection caused by pathogenic E. coli in poultry and lower risks associated with foodborne transmission of E. coli to humans through poultry and poultry products.

Poult Sci 2024; 103:103955. [PMID: 38917608 PMCID: PMC11255943 DOI: 10.1016/j.psj.2024.103955] [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: 12/30/2023] [Revised: 06/03/2024] [Accepted: 06/03/2024] [Indexed: 06/27/2024] Open
Abstract
This systematic review aimed at investigating the role that biosecurity can have in preventing or controlling colibacillosis in broiler production. Primary studies with natural or experimental exposure to avian pathogenic Escherichia coli, evaluating any biosecurity measure to prevent or control colibacillosis in broiler chickens with at least one of the following outcomes: feed conversion ratio (FCR), condemnations at slaughter, and mortality due to colibacillosis, were included. A systematic search was carried out in 4 databases according to the Cochrane handbook and reported following the PRISMA 2020 directions. Studies (n = 3,886) were screened in a 2-phase process and data matching the inclusion criteria were extracted. Risk of bias assessment was performed. Four studies reporting biosecurity measures to prevent or control colibacillosis in broiler production were included. In all studies, only disinfection during either the pre-hatching period (n = 3) or the post-hatching period (n = 1) was evaluated as biosecurity measure in broiler production, as well as its effect on FCR (n = 2) and mortality (n = 4) due to colibacillosis. No studies with effects on condemnations at slaughter were found. Due to the heterogeneity of studies in regard to interventions and outcomes, meta-analysis was not carried out. The limited findings of this systematic review do not provide a comprehensive evidence to statistically evaluate the efficacy of biosecurity to prevent or control colibacillosis in broiler production. The scarcity of evidence found suggests that further and deeper investigations on the topic are needed, considering the variety of interventions related to biosecurity.

Avian pathogenic Escherichia coli infection causes infiltration of heterophilic granulocytes of chick tracheal by the complement and coagulation cascades pathway. BMC Vet Res 2023; 19:262.

Abstract
BACKGROUND Avian pathogenic Escherichia coli (APEC) causes tracheal damage and heterophilic granulocytic infiltration and inflammation in infected chicks. In this study, we infected chick tracheal tissue with strain AE17 and produced pathological sections with proteomic sequencing. We compared the results of pathological sections from the APEC-infected group with those from the PBS control group; the pathological sections from the experimental group showed hemorrhage, fibrinization, and infiltration of heterophilic granulocytes in the tracheal tissue. In order to explore the effect on proteomics on inflammation and to further search for the caus. RESULTS The tandem mass tag-based (TMT) sequencing analysis showed 224 upregulated and 140 downregulated proteins after infection with the AE17 strain. Based on the results of KEGG in Complement and coagulation cascades, differential protein expression in the Protein export pathway was upregulated. CONCLUSIONS With these results, we found that chemokines produced by the Complement and coagulation cascades pathway may cause infiltration of heterophilic granulocytes involved in inflammation, as well as antimicrobial factors produced by the complement system to fight the infection together.These results suggest that APEC causes the infiltration of heterophilic granulocytes through the involvement of the complement system with serine protease inhibitors.

J Glob Antimicrob Resist 2023; 35:325-331. [PMID: 37918785 DOI: 10.1016/j.jgar.2023.10.015] [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: 02/18/2023] [Revised: 10/03/2023] [Accepted: 10/21/2023] [Indexed: 11/04/2023] Open
Abstract
OBJECTIVES The production of expanded-spectrum beta-lactamases (ESBLs) and fluoroquinolone resistance in Enterobacteriaceae has become a global concern. The aim of this study was to investigate the spread of ESBL-producing and fluoroquinolone-resistant avian pathogenic Escherichia coli (APEC) in Kagoshima, a prefecture with the largest amount of poultry in Japan. METHODS The antimicrobial susceptibility and genetic characteristics of 228 APEC strains isolated from 57 farms in Kagoshima Prefecture, Japan, between 2005 and 2017 were analysed. Information about the companies with hatcheries connected to the farms was also collected, and the epidemiologic relatedness of APEC strains and the processes of adopting chicks were compared. RESULTS Seven CTX-M-type ESBL genes, blaCTX-M-1, blaCTX-M-2, blaCTX-M-14, blaCTX-M-15, blaCTX-M-25, blaCTX-M-55, and blaCTX-M-65, were found in 60 (26.3%) of the 228 APEC strains. The ciprofloxacin-resistant strains belonged to 10 different sequence types (ST10, ST23, ST93, ST155, ST156, ST350, ST359, ST602, ST648, and ST9479), and the two ST602 strains showed remarkably high ciprofloxacin resistance (MIC: 128 µg/mL) and had amino acid mutations in GyrA (S83L and D87N), ParC (S80I), and ParE (E460A). A CTX-M-55-type ESBL-producing fluoroquinolone-resistant Og78-ST23 strain was isolated multiple times over two years on a farm. Furthermore, epidemiologically closely related strains were isolated from different farms that used the same common hatcheries. CONCLUSIONS APEC is often transferred from hatcheries to farms via healthy chicks, and the prudent use of antimicrobials and careful monitoring of resistant strains on poultry farms and hatcheries are important in preventing the selection and spread of high-risk APEC strains such as CTX-M-55-type ESBL-producing Og78-ST23.

Abstract
Background and Aim Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli strains exhibit antibiotic resistance and are known to infect humans worldwide. This study assessed the phenotypic and genotypic prevalence of ESBL-resistant E. coli isolates recovered from the respiratory tracts of chickens in El-Sharkia Governorate, Egypt. Materials and Methods We obtained 250 lung samples (one lung/bird) from 50 chicken farms (5 chickens/farm) to isolate, identify, and serotype E. coli. Antimicrobial resistance susceptibility was determined using the disk diffusion method, while the ESBL phenotype was identified using double disk synergy. We detected the β-lactamase genes, blaTEM, and blaSHV, using a polymerase chain reaction. Results The results showed that 140/250 (56%) were infected with E. coli. All the serogroups of isolated E. coli exhibited high multi-antimicrobial resistance index values (>0.2), and 65.7% were confirmed to have ESBL. Among the isolates with the ESBL phenotypes, 55 (60%) and 32 (35%) contained the blaTEM and blaSHV genes, respectively. Conclusion The widespread distribution of multidrug-resistant and ESBL-producing E. coli among poultry farms is a significant human health hazard. These results will help the Egyptian authorities to implement a national one-health approach to combat the antimicrobial resistance problem.

Abstract
Avian pathogenic Escherichia coli (APEC) is closely related to extraintestinal pathogenic E. coli, which are frequently assigned to specific phylogenetic groups (phylogroups). Therefore, we investigated the association between phylogroups of E. coli isolates and those recovered from commercial broiler and layer chickens with colibacillosis. We used 104 E. coli isolates from chickens with colibacillosis (hereafter referred to as “colibacillosis-related isolates”), 56 E. coli isolates obtained from fecal samples of clinically healthy broiler chickens, and 58 isolates obtained from environmental samples of layer chicken housing facilities where clinically healthy layer chickens were reared (hereafter referred to as “healthy chicken-related isolates”). The prevalence of phylogroup F among colibacillosis-related isolates was significantly (P < 0.05) higher than that among healthy chicken-related isolates, while phylogroups A and B1 were more frequently distributed in healthy chicken-related isolates. Fifty-seven (87%) of 65 colibacillosis-related isolates belonging to phylogroup F were defined as APEC based on the presence of virulence-associated genes according to a previously established criterion. In contrast, none of the healthy chicken-related isolates were defined as APEC. As evidenced by the chicken embryo lethality assay, 87 of the 92 healthy chicken-related isolates tested had embryo lethality rates of <30% and were considered avirulent, whereas 59 of the 104 colibacillosis-related isolates were considered virulent. Nonetheless, among isolates exhibiting embryo lethality rates of <30%, the mean lethality rate of embryos inoculated with colibacillosis-related isolates was significantly higher than that of embryos inoculated with healthy chicken-related isolates. These observations suggest that phylogroup F predicts colibacillosis among E. coli strains with virulence-associated genes.

Abstract
Antimicrobial resistance (AMR) remains a major global public health crisis. The food animal industry will face escalating challenges to increase productivity while minimizing AMR, since the global demand for animal protein has been continuously increasing and food animals play a key role in the global food supply, particularly broiler chickens. As chicken products are sources of low-cost, high-quality protein, poultry production is an important economic driver for livelihood and survival in developed and developing regions. The globalization of the food supply, markedly in the poultry industry, is aligned to the globalization of the whole modern society, with an unprecedented exchange of goods and services, and transit of human populations among regions and countries. Considering the increasing threat posed by AMR, human civilization is faced with a complex, multifaceted problem compromising its future. Actions to mitigate antimicrobial resistance are needed in all sectors of the society at the human, animal, and environmental levels. This review discusses the problems associated with antimicrobial resistance in the globalized food chain, using the poultry sector as a model. We cover critical aspects of the emergence and dissemination of antimicrobial resistance in the poultry industry and their implications to public health in a global perspective. Finally, we provide current insights using the multidisciplinary One Health approach to mitigate AMR at the human-animal-environment interface.

Abstract
T6SS (type VI secretion system) is a kind of nano syringe that exists in APEC (Avian pathogenic Escherichia coli). Hcp (haemolysin-coregulated protein) of T6SS participates in the regulation of virulence during APEC infection. However, whether hcp plays a role in bacterial colonization by expressing in host cells remains unclear. In this study, we analysed the biological characteristics of the mutant hcp2b strain. Our results showed that the hcp2b gene was involved in the regulation of bacterial motility, biofilm formation, anti-serum and anti-oxidative stress. Moreover, our data indicate that the colonization of the hcp2b mutation strain (Δhcp2b) in the lung, liver and kidney of chickens decreased significantly. Hence, overexpression of Hcp2b protein in DF-1 cells was used to analyse the effect of Hcp2b on colonization of APEC. Proteomics analysis showed that overexpression of Hcp2b induced differentially expressed proteins of DF-1 cells (230 were significantly upregulated and 96 were significantly downregulated) and differentially expressed proteins were enriched in keratin filament item. In conclusion, our data indicated that hcp2b promoted the colonization of APEC by affecting the expression of keratin filament.

Abstract
Colibacillosis, an infectious disease of chickens, is caused by avian pathogenic Escherichia coli (APEC); however, in addition to APEC, other pathogens are also frequently isolated from chickens affected with colibacillosis. Therefore, experimental infections in chickens are necessary to evaluate the pathogenicity of APEC isolates. Recent studies have shown that embryo lethality assays can be used as an alternative method to evaluate the pathogenicity of E. coli. In this study, to determine the important virulence genes associated with the pathogenicity of E. coli, 67 strains of E. coli that possessed different combinations of eight representative virulence genes (cva/cvi, vat, tsh, iucD, papC, irp2, iss, and astA) were isolated from broilers with colibacillosis in Japan, and the chicken embryo lethal assay was conducted. The genes vat, papC, and irp2 showed strong correlation with the level of virulence in E. coli. Our study provides useful information about the important virulence-associated genes in relation to the pathogenicity of E. coli in Japanese chickens.

Avian Pathogenic Escherichia coli (APEC): An Overview of Virulence and Pathogenesis Factors, Zoonotic Potential, and Control Strategies. Pathogens 2021; 10:pathogens10040467.

Abstract
Avian pathogenic Escherichia coli (APEC) causes colibacillosis in avian species, and recent reports have suggested APEC as a potential foodborne zoonotic pathogen. Herein, we discuss the virulence and pathogenesis factors of APEC, review the zoonotic potential, provide the current status of antibiotic resistance and progress in vaccine development, and summarize the alternative control measures being investigated. In addition to the known virulence factors, several other factors including quorum sensing system, secretion systems, two-component systems, transcriptional regulators, and genes associated with metabolism also contribute to APEC pathogenesis. The clear understanding of these factors will help in developing new effective treatments. The APEC isolates (particularly belonging to ST95 and ST131 or O1, O2, and O18) have genetic similarities and commonalities in virulence genes with human uropathogenic E. coli (UPEC) and neonatal meningitis E. coli (NMEC) and abilities to cause urinary tract infections and meningitis in humans. Therefore, the zoonotic potential of APEC cannot be undervalued. APEC resistance to almost all classes of antibiotics, including carbapenems, has been already reported. There is a need for an effective APEC vaccine that can provide protection against diverse APEC serotypes. Alternative therapies, especially the virulence inhibitors, can provide a novel solution with less likelihood of developing resistance.

Abstract
E. coli infection of broilers can result in systemic diseases and productivity losses. Use of antimicrobials against this condition is common but other approaches, such as vaccination, are gaining ground. Anecdotal field reports indicate that intestinal health is improved unspecifically following E. coli live vaccination. We hypothesized that the intestine may be an important site for the functionality of the vaccine. Vaccine effects on the intestine were assessed. Spray vaccination induced marked alterations of the caecum microbiota of broilers within 3 days, and this effect gradually waned. However, T cell activation occurred in the spleen, but not in caecal tonsils, and anti-E. coli IgA was concentrated in the respiratory mucosae. Accordingly, IL-6 mRNA was produced in the lungs following immunization. Overall, these data are an initial indication that any vaccine-induced effects on the intestine are greatly associated with the microbiota. However, immunity conferred by vaccination is not primarily induced in gut-associated lymphoid tissues.

Abstract
Avian pathogenic Escherichia coli (APEC) causes significant economic losses in poultry industries. Here, we determined for the first time in Bangladesh, the prevalence of APEC-associated virulence genes in E. coli isolated from layer farms and their antibiotic resistance patterns. A total of 99 samples comprising internal organs, feces, and air were collected from 32 layer farms. Isolation was performed by culturing samples on eosin–methylene blue agar plates, while the molecular detection of APEC was performed by PCR, and antibiograms were performed by disk diffusion. Among the samples, 36 were positive for the APEC-associated virulence genes fimC, iucD, and papC. Out of 36 isolates, 7, 18, and 11 were positive, respectively, for three virulence genes (papC, fimC, and iucD), two virulence genes, and a single virulence gene. Although the detection of virulence genes was significantly higher in the internal organs, the air and feces were also positive. The antibiograms revealed that all the isolates (100%) were resistant to ampicillin and tetracycline; 97.2%, to chloramphenicol and erythromycin; 55.5%, to enrofloxacin; 50.0%, to norfloxacin and ciprofloxacin; 19.4%, to streptomycin; 11.1%, to colistin; and 8.33%, to gentamicin. Interestingly, all the isolates were multidrug-resistant (MDR). Spearman’s rank correlation coefficient analysis revealed the strongest significant correlation between norfloxacin and ciprofloxacin resistance. This is the first study in Bangladesh describing the molecular detection of APEC in layer farms. Isolated APEC can now be used for detailed genetic characterization and assessing the impact on public health.

Abstract
Plasmid-mediated quinolone resistance (PMQR) is a potential concern for animal husbandry and public health. Escherichia coli isolates from a total of 109 fecal samples collected from 6 commercial broiler farms between 2007 and 2011 were examined for PMQR genes, and transfer of these genes was tested by conjugation analysis to elucidate the prevalence and spread of PMQR in broiler chickens. Two isolates from 2 farms harbored the aac(6')-Ib-cr gene that was not detected in plasmids using Southern blot analysis of S1 nuclease-digested genomic DNA separated by pulsed-field gel electrophoresis. In these 2 isolates, nucleotide mutations in the gyrA and parC genes that result in amino acid substitutions were detected. Additionally, a total of 6 isolates originating from 6 chickens from the 2 farms were positive for the qnrS1 gene. In 2 of the 6 isolates, the qnrS1 gene was transferred to a recipient strain. Two transconjugants harboring the qnrS1 gene were cultured on media supplemented with successively higher concentrations of enrofloxacin (ERFX). After a 5-time subcultivation, the ERFX MICs reached 8 and 16 μg/mL, and no nucleotide mutations were detected in the gyrA, gyrB, parC, and parE genes. Our results suggest that the prevalence of PMQR was relatively low in broiler chickens and that exposure of bacteria carrying PMQR genes to the selective pressure of fluoroquinolones can result in resistance to fluoroquinolone, which is not caused by mutations in genes encoding topoisomerases.

Abstract
Plasmid-mediated quinolone resistance (PMQR) genes located on conjugative plasmids can be transferred to other bacteria in the absence of antimicrobial selective pressure. To elucidate the prevalence of resistance, including PMQR in an egg-producing commercial layer farm in western Japan where no antimicrobials were used, minimum inhibitory concentrations (MIC) for a total of 375 Escherichia coli isolates obtained from chicken houses in the farm between 2012 and 2017 were determined using the agar dilution methods. Eighty-seven isolates resistant to oxytetracycline (OTC) accounted for 23.0% of the tested isolates, followed by isolates resistant to dihydrostreptomycin (DSM) (18.4%), sulfisoxazole (18.1%), ampicillin (AMP) (14.4%), trimethoprim (TMP) (14.4%), and nalidixic acid (10.1%). The prevalence rate of multidrug-resistant (MDR) isolates—which are resistant to 3 or more antimicrobial classes, including β-lactams, aminoglycosides, quinolones, folate pathway inhibitors, tetracyclines, and phenicols—was inversely related to the age of chickens at the time of bacterial examination. Probably, the prevalence of MDR isolates in layer chickens may have decreased with age owing to the absence of selective pressure. Furthermore, 45 isolates exhibiting enrofloxacin MICs of more than 0.25 μg/mL were examined for PMQR genes. The transfer of PMQR genes was tested by conjugation analysis. Southern blot analysis of genomic DNA revealed that the qnrS1 (5 isolates), qnrS2 (1 isolate), and qnrS13 genes (1 isolate) were located on plasmids with sizes ranging from approximately 60 to 120 kpb. In 1 of the 5 qnrS1-positive isolates and in an isolate with qnrS13, the qnrS genes were transferred to recipient strains. The plasmid harboring the qnrS1 gene was typed as IncF by PCR-based replicon typing. On this plasmid, the blaTEM, aadA, tetA, and dfrA1 genes responsible for resistance to AMP, DSM, OTC, and TMP, respectively, were detected. The tetA gene was detected in the plasmid harboring the qnrS13 gene, which was typed as IncI1. These results suggest that despite the low prevalence of quinolone resistance in this farm, various PMQR genes, located on diverse plasmids, exist.

Abstract
Avian pathogenic Escherichia coli (APEC) causes extensive mortality in poultry flocks, leading to extensive economic losses. The aim of this study was to investigate the phenotypic and genotypic characteristics and antimicrobial resistance of recent APEC isolates. Of the 79 APEC isolates, the most predominant serogroup was O78 (16 isolates, 20.3%), followed by O2 (7 isolates, 8.9%) and O53 (7 isolates, 8.9%). Thirty-seven (46.8%) and six (7.6%) of the isolates belonged to phylogenetic groups D and B2, respectively, and presented as virulent extraintestinal E. coli. Among 5 analyzed virulence genes, the highest frequency was observed in hlyF (74 isolates, 93.7%), followed by iutA (72 isolates, 91.9%) gene. The distribution of the iss gene was significantly different between groups A/B1 and B2/D (P < 0.05). All group B2 isolates carried all 5 virulence genes. APEC isolates showed high resistance to ampicillin (83.5%), nalidixic acid (65.8%), tetracycline (64.6%), cephalothin (46.8%), and ciprofloxacin (46.8%). The β-lactamases–encoding genes blaTEM-1 (23 isolates, 29.1%), blaCTX-M-1 (4 isolates, 5.1%), and blaCTX-M-15 (3 isolates, 3.8%); the aminoglycoside-modifying enzyme gene aac(3)-II (4 isolates, 5.1%); and the plasmid-mediated quinolone genes qnrA (10 isolates, 12.7%) and qnrS (2 isolates, 2.5%) were identified in APEC isolates. The tetA (37 isolates, 46.8%) and sul2 (20 isolates, 25.3%) were the most prevalent among tetracycline and sulfonamide resistant isolates, respectively. This study indicates that APEC isolates harbor a variety of virulence and resistance genes; such genes are often associated with plasmids that facilitate their transmission between bacteria and should be continuously monitored to track APEC transmission in poultry farms.

Abstract
In many countries including Japan, the status of emerging antimicrobial resistance among Serratia spp. and Citrobacter spp. in companion animals remains unknown because these genera are rarely isolated from animals. In this study, 30 Serratia spp. and 23 Citrobacter spp. isolates from companion animals underwent susceptibility testing for 10 antimicrobials. Phenotypic and genetic approaches were used to identify the mechanisms of extended-spectrum cephalosporins (ESC). Subsequently, ESC-resistant Citrobacter spp. strains underwent multilocus sequence typing and pulsed-field gel electrophoresis (PFGE). A significantly higher rate (34.8%) of ESC resistance was observed in Citrobacter spp. isolates than in Serratia spp. isolates (0%). ESC resistance was detected in five C. freundii strains, two C. portucalensis strains, and one C. koseri strain. All of the ESC-resistant Citrobacter spp. strains harbored CMY-type and/or DHA-type AmpC β-lactamases. Three C. freundii strains harbored the CTX-M-3-type extended-spectrum β-lactamases. Notably, the three blaCTX-3-producing and two blaCMY-117-bearing C. freundii strains (obtained from different patients in one hospital) had the same sequence type (ST156 and ST18, respectively) and similar PFGE profiles. We believe that ESC-resistant Citrobacter spp. are important nosocomial pathogens in veterinary medicine. Therefore, infection control in animal hospitals is essential to prevent dissemination of these resistant pathogens.
