RESUMO

Mindfulness has been practiced by global leaders and companies as an efficient way to build effective leadership. Because of its popularity, plus the lack of a comprehensive theoretical framework that explains it in a leadership context, the research literature has called for a coherent account of the qualities that is derived by those leaders that practice mindfulness. Here, we aim to answer that call, by clarifying what leadership qualities can develop from practicing mindfulness. We report on a semi-systematic literature review of extant research, covering 19 research articles published between 2000 and 2021, plus other relevant supporting literature from the disciplines of leadership and neuropsychology. Our proposed framework consists of three main qualities of the mindful leader: attention, awareness, and authenticity. We call them the "three pillars of mindful leaders." We also propose that mindfulness meditation must be integrated into our proposed framework, as we are convinced that leaders who hope to benefit from these qualities must integrate a regular mindfulness meditation practice into their daily leadership life.

RESUMO

For children, meaningful participation in community life includes being able to access places for play. Such community playspaces are potentially important for all children, including those with disabilities. Yet, children are rarely asked for their views on the design of playspaces, which can further contribute to exclusionary practices and undermine children's rights to share their views on matters that affect them. In this scoping review, we aim to analyze guidelines and identify strategies for supporting children's participation rights when planning public playspaces. Guidelines are practical tools used by local policymakers when creating community playspaces, which are important sites for children's outdoor play. In total, forty-two guidelines were identified that addressed children's participation rights, along with community involvement. Qualitative evidence synthesis with a "best fit" framework approach was used, informed by Lundy's model of children's participation. The findings revealed the importance of initial community involvement as a critical prerequisite. Strategies for children's participation mostly concerned "space and voice" (for children of diverse abilities), with little attention paid to giving their views due weight. This evidence shows that there is a significant gap in knowledge surrounding policy development and implementation to support adults and children to cooperate equally in designing playspaces. Future directions for research in children's participation require a focus on combined community-children participation approaches in public playspace design. Such work could strengthen and facilitate the role of adults as bearers of the duty to implement the rights of children. This review generated inclusive strategies in planning public playspaces, which could support local policymakers in this complex multi-layered process.

RESUMO

For children, playgrounds are important environments. However, children's perspectives are often not acknowledged in playground provision, design, and evaluation. This scoping review aimed to summarize the users' (children with and without disabilities) perspectives on environmental qualities that enhance their play experiences in community playgrounds. Published peer-reviewed studies were systematically searched in seven databases from disciplines of architecture, education, health, and social sciences; 2905 studies were screened, and the last search was performed in January 2023. Included studies (N = 51) were charted, and a qualitative content analysis was conducted. Five themes were formed which provided insights into how both physical and social environmental qualities combined provide for maximum play value in outdoor play experiences. These multifaceted play experiences included the desire for fun, challenge, and intense play, the wish to self-direct play, and the value of playing alone as well as with known people and animals. Fundamentally, children wished for playgrounds to be children's places that were welcoming, safe, and aesthetically pleasing. The results are discussed in respect to social, physical, and atmospheric environmental affordances and the adult's role in playground provision. This scoping review represents the valuable insights of children regardless of abilities and informs about how to maximise outdoor play experiences for all children.

RESUMO

IMPORTANCE: Internationally, it is suggested that school-based occupational therapy (SBOT) has an important role in supporting inclusion in educational settings. In SBOT, multitiered service delivery models are identified as a way forward to maximize school inclusion. Therefore, identifying evidence for the implementation of tiered interventions in SBOT is vital. OBJECTIVE: To identify and map evidence in the occupational therapy literature relating to SBOT interventions delivered in elementary schools for all children, for those at risk, and for those with identified diagnoses. DATA SOURCES: Peer-reviewed literature published in 14 occupational therapy journals between 1990 and 2020, indexed in the EBSCOhost database. STUDY SELECTION AND DATA COLLECTION: Included studies were those within the scope of SBOT that reported on school occupations and focused on elementary school-age children (excluding kindergarteners or preschoolers). FINDINGS: Forty studies met the criteria. Individual-tier intervention studies (n = 22) primarily reported direct interventions with children at risk or with identified diagnoses (Tier 2 or Tier 3), focusing mostly on remedial approaches. None adopted a whole-school approach. Despite handwriting and self-regulation being dominant areas of concern, these studies were not explicitly related to inclusion outcomes. Evidence for implementing multitiered models primarily used indirect, collaborative consultation, embedded in the school context (n = 18). These studies identified positive school staff and child outcomes when collaboration was timely, consistent, and authentic. CONCLUSIONS AND RELEVANCE: More rigorous individual-tier intervention studies are required to inform the design and implementation of multitiered interventions in SBOT and to support participation and inclusion in schools. What This Article Adds: This scoping review provides evidence to support occupational therapists' professional reasoning in developing evidence-based, contextual, educationally relevant multitiered models of intervention in SBOT.

RESUMO

Introduction: Occupational therapists often use play-based approaches to facilitate children's occupational development and promote participation, for example, play-based occupational therapy, play therapy and playwork. However, where does play occupation fit, within these adult-guided play-based approaches in occupational therapy? Purpose: To examine and discuss the play-work occupation continuum of children to inform occupational therapy practice. Key Issues: Children's play occupations are free-selected, unstructured, internally-controlled, spontaneous and intrinsically-motivated. Yet, occupational therapists often utilize play as a therapeutic modality to support occupational development for occupations other than play. This use of play represents play-based work occupations as they are structured, externally-controlled, adult-guided, goal-focused and extrinsically-motivated. Play occupations then move from being authentic free-play to adult-guided play-based work occupations for children. Implications: When working with children and families, occupational therapists need to balance the use of self-selected, unstructured play occupations with the application of adult-guided, structured, goal-focused play-based work occupations.

RESUMO

PURPOSE: Public playgrounds afford children and families important opportunities for outdoor play, social participation, and inclusion. Unfortunately, many children and families experience barriers to accessing, using, and being included in public playgrounds. Consequently, Universal Design (UD) is promoted for providing conceptual guidance for designing for inclusion in public playgrounds. However, a lack of research evidence means researchers have engaged in the ongoing interpretation of the UD concept and related non-discriminatory planning and design concepts. Therefore, the aim of this study was to examine how UD, and related concepts, are used in peer-reviewed articles concerning public playgrounds. MATERIALS AND METHODS: A scoping review was conducted in November 2019, which identified 15 peer-reviewed articles that met the inclusion criteria. RESULTS: Analysis revealed that the terms UD, inclusive design, accessibility, and usability are all being used to describe non-discriminatory planning and design concepts arbitrarily and without regard for higher or lower order concepts. Two broad interpretations were evident: (a) UD is synonymous with accessibility for some, and (b) UD is a higher-order concept that goes beyond accessibility for others. Nevertheless, findings highlight the utility of UD in underpinning the design of public playgrounds in many developed countries; however, the concept requires further clarity and specificity as it pertains to playground design and more pertinently inclusion in outdoor play. CONCLUSIONS: We argue for further conceptual refinement to consolidate the importance and future application of UD for Play (UDP) in the design of public playgrounds that promote outdoor play, social participation, and inclusion.IMPLICATIONS FOR REHABILITATIONMost peer-reviewed journal articles reviewed fail to define what is meant by the term Universal Design.Of those that do provide a definition, the outcome of inclusion in play, or the application of Universal Design to enable play in public playgrounds was unclear.Research to date has mostly focused on related concepts, including accessibility and usability, with less emphasis on Universal Design.Recommend a tailored perspective of Universal Design for Play (UDP).

RESUMO

Autistic children with sensory processing differences successfully navigate and engage in meaningful family daily occupations within home and community environments through the support of their family. To date however, much of the research on autistic children with sensory processing differences, has primarily been deficit focused, while much of the caregiver research has focused on issues of distress, burden, effort, and emotional trauma in coping with their child's diagnosis. This study aimed to conduct a qualitative evidence synthesis, using a meta-ethnographic approach to explore the gap identified in understanding successful occupational experiences of family participation and daily family routines when supporting an autistic child with sensory processing differences and to offer an alternative strengths-based perspective. Inclusion criteria were studies which were peer-reviewed qualitative design, published from 2000 to 2021, and that concerned parents/caregivers' perspectives of family occupations of children diagnosed with autism spectrum disorder. Studies were electronically searched in eight databases from October to December 2021 and 23 studies were identified which met the inclusion criteria. Noblit and Hare's seven step approach for conducting analysis in meta-ethnography was used, and three themes identified: (1) sensory processing differences in daily life, (2) what is hard about hard, and (3) orchestrating family life. Results identified the centrality of sensory experiences in understanding family life. Living with unpredictability while orchestrating certainty through routines was core to successful participation. This review provides insights into how parents negotiate the complexities of constructing family life when living with an autistic child. The results can inform the design of future interventions that specifically address the relationship between meaningful participation in family occupations and daily routines and sensory processing in autistic children.

RESUMO

AIMS: The aim was to exploit whole genome sequencing (WGS) to assess genomic diversity, identify virulence genes and deduce the proportion of Campylobacter colonized broilers that directly contaminate their carcasses. METHODS AND RESULTS: Campylobacter jejuni isolates (107) from caeca and carcass neck skin samples (50 pairs from the same batch plus 7 individual caeca) sampled at three poultry slaughterhouses over a one-year period were selected for sequencing (MiSeq; Illumina). FastQ files were submitted to BioNumerics for analysis using the wgMLST scheme for allele calling. Campylobacter cgMLST and hierarchical clustering was performed by applying the single linkage algorithm. Sequence types (STs) were determined in silico from the WGS data and isolates were assigned into clonal complexes (CCs) using the Campylobacter PubMLST.org database. Virulence genes were determined by downloading core sequences from the virulence factor database (VFDB) and the National Center for Biotechnology Information (NCBI). A high degree of diversity was observed with 23 different STs identified. ST257 and CC-21 were the most common STs and CCs, respectively. cgMLST analysis suggested that 56% of carcass contamination was a direct result of contamination from caeca from the same batch. Virulence genes known to play a role in human C. jejuni infection were identified such as the wlaN gene and the genes associated with lipooligosaccharide synthesis, which were identified in 30% of isolates. CONCLUSIONS: Caecal colonization was the more plausible occurring source of C. jejuni contamination of broiler carcasses, compared with cross-contamination from another batch or the environment. The high rate of genetic diversity observed amongst caecal isolates is consistent with a wide variety of Campylobacter strains circulating in poultry flocks in Ireland. SIGNIFICANCE AND IMPACT OF STUDY: The results will further inform broiler processors and regulators about the influence and importance of on-farm colonization versus slaughterhouse cross-contamination and the relationship between C. jejuni in caeca and carcasses during processing.

RESUMO

Campylobacter is the most common foodborne pathogen in developed countries and most cases are associated with poultry. This study investigated the effect of three anti-Campylobacter water additives on broiler growth and on the caecal microbiota at harvest using 16S rRNA amplicon sequencing. Mixtures of organic acids (OA) and essential oils (EO) were administered to broilers for the entirety of the production cycle (35 d) and medium-chain fatty acids (MCFA) for 5 d immediately before harvest, under commercial conditions. Bird weight gain was significantly (p < 0.001) reduced in broilers receiving the OA and EO treatments. While this was most likely due to reduced water intake and corresponding lower feed consumption, changes to the caecal microbiota may also have contributed. Firmicutes made up over 75% of the bacteria regardless of sample type, while the minor phyla included Bacteroidetes, Actinobacteria, Melainabacteria, and Proteobacteria. There were no significant (p > 0.05) differences in the alpha diversity as measured using ACE, Chao1, and Shannon indices, except for control (water) versus MCFA and OA versus MCFA, using the Wilcox test. In contrast, there was a significant (p < 0.05) difference in beta diversity when the treated were compared to the untreated control and main flock samples, while linear discriminant analysis effect size (LeFSe) identified three OTUs that were present in the control but absent in the treated birds. It was concluded that the water additives tested adversely affected broiler performance, which may, at least in part, be due to changes in the caecal microbiota, assuming that the altered microbiota at day 35 is indicative of a change throughout the production cycle.

RESUMO

16S rRNA amplicon sequencing was used to investigate changes in the broiler gastrointestinal tract (GIT) microbiota throughout the rearing period and in combination with antibiotic treatment. Thirty birds (from a commercial flock) were removed at multiple points throughout the rearing period on days 13, 27, and 33, euthanised, and their GIT aseptically removed and divided into upper (the crop, proventriculus, and the gizzard), middle (the duodenum, jejunum, and ileum) and lower (the large intestine, the caeca, and the cloaca) sections. In a separate commercial flock, on the same farm with similar husbandry practices and feed, doxycycline (100 mg/ml per kg body weight) was administered in drinking water between day 8 and 12 (inclusive) of the production cycle. Birds were removed on days, 13, 27, and 33 and GIT samples prepared as above. The contents of three merged samples from each GIT section were pooled (n = 60), the DNA extracted and analysed by 16S rRNA amplicon metagenomic sequencing and analysed. Major changes in the broiler microbiota were observed as the birds aged particularly with the Firmicutes/Bacteroidetes ratio (F:B) of the lower GIT. Moreover, Chao1, ACE, and Shannon indices showed the antibiotic treatment significantly altered the microbiota, and this change persisted throughout the rearing period. Further research is required to investigate the effect of these changes on bird performance, susceptibility to infections and Campylobacter carriage.

RESUMO

In 2008, an EU wide baseline survey of broilers revealed a high Campylobacter prevalence. To assist with industry-wide controls, updated data were required. The primary objective of this study was to establish up-to-date data on Campylobacter carriage and carcass contamination in Irish broilers. Monthly samples were collected from the three largest broiler processing plants in Ireland over a twelve-month period. Samples were taken from both first and final thin birds (partial and full depopulation) from 358 batches of broilers. From each batch, a composite sample of 10 caecal contents (n = 358) and 5 neck skins (n = 1790) were collected and numbers of Campylobacter in each sample were determined. Of the 1790 neck skin samples tested, 53% were Campylobacter positive. Campylobacter was detected in the caecal contents of 66% of all batches tested. Depopulation and/or age had a significant effect on Campylobacter prevalence with 67% of final thin broilers yielding Campylobacter-positive neck skin samples in contrast to 38% of first thin broilers that yielded positive neck skin samples (P ≤ 0.002). A significant seasonal variation was observed in the rate of Campylobacter-positive caecal samples with higher prevalence seen in July (85%) than the colder months of November (61%), December (50%), January (61%) March (57%) and April (59%). Neck skin samples were 7 times more likely to be Campylobacter positive if the caecal contents from the same batch were positive (odds ratio = 7.1; P ≤ 0.0001). The decrease in Campylobacter prevalence observed in neck skin and caecal contents demonstrates the improvements and progress made in reducing prevalences of this important enteropathogen in the Irish poultry industry since the 2008 EU baseline survey. It also provides further supporting data on the impact of thinning, the processing environment and season on Campylobacter prevalence.

RESUMO

AIMS: This research tested the anti-Campylobacter properties of organic acids (OA), medium chain fatty acids (MCFA) and essential oils (EO) in vitro and commenced in vivo suitability testing focused on broiler performance. METHODS AND RESULTS: Nine active compounds were tested at different concentrations and times against Campylobacter jejuni in sterile distilled water, Mueller Hinton broth and grower feed digestate (GFD). Sodium caprate (1.5%, v/v), thymol (0.25% and 2.5%, v/v), carvacrol (1.25%, v/v) and potassium sorbate (1.5%, v/v) each achieved C. jejuni reductions of ≥4.5 log10  CFU per ml in GFD, the matrix most representative of the broiler gut, after 60 s. Similar reductions were achieved after 60 min with lactic acid (1.25%, v/v), formic acid (3.1%, v/v), sodium caprylate (1.5%, v/v) and carvacrol (1.25%, v/v). However, in vivo these compounds adversely affected broiler performance, resulting in dimished water intake and reduced weight. CONCLUSIONS: OA, MFCA and EO based compounds are effective anti-Campylobacter treatments in laboratory model studies but cannot be applied in vivo. SIGNIFICANCE AND IMPACT OF THE STUDY: This study illustrates that OAs, MCFAs and EOs can achieve significant reductions in Campylobacter in vitro but identifies a major issue, inhibition of broiler performance, preventing their use in practice.

RESUMO

PURPOSE: To synthesize evidence regarding the physical design features and non-physical aspects of public playgrounds that facilitate/hinder outdoor play, social participation, and inclusion; identify design recommendations; and explore the current discourses and concepts around designing for outdoor play, social participation, and inclusion in public playgrounds in the context of Universal Design (UD). METHODS: Published studies addressing public playgrounds, inclusion, and design, were identified via a systematic search of eleven databases from health, science, education, and humanities. RESULTS: Fifteen documents met the inclusion criteria. Three main themes were identified concerning physical design features and non-physical aspects of public playgrounds that facilitate/hinder outdoor play, social participation, and inclusion, with associated design recommendations. Although UD is recognized to have the potential to support the design of public playgrounds, no studies examined UD solutions for playgrounds or tested them for effectiveness. CONCLUSION: We cannot yet determine whether UD can support outdoor play, social participation, and inclusion in public playgrounds. Research to date has mostly focused on understanding users' perspectives; future research should continue to be informed by diverse users' perspectives to address gaps in knowledge concerning children's voice from migrants, lower socioeconomic communities, and intergenerational users with disabilities alongside researching design solutions for play.Implications for rehabilitationChildren, particularly children with disabilities and their families, continue to experience marginalization and exclusion in public playgrounds, despite a commitment to inclusion in international treaties.Universal design is recognized to have the potential to support the design of public playgrounds, however, the evidence is currently very sparse.While accessibility is an important consideration for playground design, it does not ensure that play occupations can take place.Extending knowledge on universal design as it applies explicitly to playgrounds and play occupation requires multi- and trans-disciplinary collaboration that includes a play-centered perspective.

RESUMO

BACKGROUND: According to Article 12 of the United Nations Convention on the Rights of the Child, therapists are duty-bound to include children in decisions that impact them. Although occupational therapists champion client-centred, collaborative practice, there remains a paucity of studies detailing children's rights and experiences of decision-making in pediatric occupational therapy. PURPOSE: This qualitative study described the decision-making experiences of children, parents and therapists in occupational therapy. METHODS: Semi-structured interviews were conducted with 17 participants (six children, five parents and six occupational therapists), and data analysed using thematic analysis. FINDINGS: Three themes emerged: 1) Goal-setting experiences; 2) Adults: child-rights gatekeepers or defenders? and 3) Decision-making in context. Findings suggest that decision-making is mostly adult directed, and children's voices are subsumed by adult-led services, priorities, and agendas. IMPLICATIONS: Children's rights need to be embedded as an aspect of best practice in providing services that are child-centred in occupational therapy practices and education.

RESUMO

PURPOSE: School is a primary setting for pediatric occupational therapy practice, yet little is known about the provision of school-based occupational therapy in many countries internationally. The purpose of this study was to explore current school-based occupational therapy practice for the first time in Ireland to gain insight into current and potential service provision and to identify new directions and potential pathways for development. METHODS: This descriptive quantitative study utilized a cross-sectional online survey to gain the perspectives of the population of pediatric occupational therapists working regularly in schools across Ireland. Respondents were recruited through convenience and snowball sampling. Data were analysed through qualitative content analysis and descriptive statistics. RESULTS: The survey elicited 35 responses, yielding a 21.2% estimated response rate. Findings demonstrated that respondents provided therapy services in schools most commonly on a weekly (28.6%) or monthly (34.3%) basis, with only 5.0% working in the same school on a weekly or fortnightly basis. The majority of respondents (54.3%) used a direct therapy approach with a child, rather than coaching or modelling, to primarily address sensory, hand function, or daily living needs. None used a whole class or whole school (universal or tiered) approach. While respondents (54.3%) generally viewed collaborative practice as a strength of school-based practice, they also identified barriers to collaboration in schools. A core barrier is related to how services are constructed across health and education, with differing philosophies of service provision. The majority of respondents (75.0%) reported that they had not received any training to deliver evidence-based practice in therapy provision specific to school-based practice. Implications for Practice. This study indicates that therapists require continual education on evidence-based school practice as it applies in an Irish context. Furthermore, clarification of school therapy roles and service delivery models are required in order to determine how they contrast with traditional clinic roles. This will enable therapists to strengthen the coordination of service delivery between health and educational services to maximize the outcomes of school-based practice.

RESUMO

This study investigates the effect of stocking density and population dynamics on broiler growth rates and productivity, while further validating the ability of the biosecurity cubes (BC) to protect birds from Campylobacter. In our methodology, six BC were constructed in a commercial broiler house containing approximately 28,500 birds. During three trials, the BC were stocked at densities of 12, 14, 16, 18, 20 and 22 birds/m2, with the main flock (20 birds/m2) considered the control. Periodically, 10 birds per density were weighed and examined. The Campylobacter status of the birds was monitored via faecal samples using the ISO 10272: 2017. The stocking density for maximum calculated yield was 20 (trials 1 and 2) or 22 birds/m2 (trial 3), followed by 18, 16, 14 and 12. At the stocking rate of 20 birds/m2, the birds in the pen grew faster than those at the same density in the main flock achieving 2 Kg 3-6 days faster. Birds in the BC were observed to be generally healthier, and in some cases, remained Campylobacter negative, even after the main flock was infected. Our results conclude that dividing the flock into sub-flocks of approximately 20 birds/m2 using BC could increase productivity up to 20%, while preventing Campylobacter.

RESUMO

This study examined the impact of key processing stages and flock variables on the prevalence of Campylobacter on broiler carcasses. Overall, the prevalence of Campylobacter was 62% in caeca, and 68%, 65% and 62% in neck skin samples collected after evisceration, final wash and carcass chilling, respectively. Campylobacter were found in 32% of caeca, and 52%, 40% and 32% of neck skin samples collected after evisceration, final wash and carcass chilling, respectively from first thin broiler batches. Final thin broiler batches were more frequently contaminated with prevalences of 83% found in caeca, 80% in neck skin samples collected after evisceration and 83% found in neck skin samples collected after both final wash and carcass chilling stages (p < 0.05). Thinning status had a significant effect on Campylobacter counts with significantly higher counts observed in samples from final thin batches (p < 0.05). Highest Campylobacter concentrations in neck skin samples were observed at the evisceration stage in both first and final thin samples, with counts ranging from 2.0 to 3.8 log10 CFU/g and 2.3 to 4.8 log10 CFU/g in first and final thin batches, respectively. All first thin samples had counts below the European Union (EU) Process Hygiene Criterion threshold level of 3 log10 CFU/g after chilling while 52% of final thin batches had counts above this limit.

RESUMO

Fostering a culture of clinical effectiveness in healthcare is crucial to achieving optimum outcomes for patients. Evidence-based practice (EBP) is a cornerstone of clinical effectiveness. An EBP capacity-building project commenced in Ireland in 2016, in collaboration with the Centre of Evidence-Based Medicine in Oxford. A key part of this project, reported here, was the development of a competency framework for education in EBP and clinical effectiveness to ensure responsiveness of education standards and curricula of healthcare professionals in this area. METHODS: Following a review of national and international reports, professional guidance documents and empirical literature pertaining to clinical effectiveness education (CEE), a preliminary competency framework was developed. Stakeholder consultations were conducted over a 6-month period, which consisted of 13 focus groups (n=45) and included representatives from clinical practice, higher education and professional training sectors, regulator/accrediting bodies, the Department of Health (Ireland) and patient/service user groups. RESULTS: An overarching interprofessional competency framework for CEE was proposed and included the following domains: EBP, quality improvement processes, implementation strategies and collaborative practice: a total of 16 competencies and 60 indicators. CONCLUSION: A competency framework for CEE for health and social care professionals is presented. It is intended that this framework will provide guidance to healthcare educators and regulators in the construction and revision of curricula, learning outcomes, teaching and assessment strategies, and graduate/clinician attributes.

Campylobacteriosis is the leading cause of human bacterial gastroenteritis, very often associated with poultry consumption. Thermophilic Campylobacter (Campylobacter jejuni and Campylobacter coli) isolates (n = 158) recovered from broiler neck skin and caecal contents in Ireland over a one-year period, resistant to at least one of three clinically relevant antimicrobial classes, were screened for resistance determinants. All ciprofloxacin-resistant isolates (n = 99) harboured the C257T nucleotide mutation (conferring the Thr-86-Ile substitution) in conjunction with other synonymous and nonsynonymous mutations, which may have epidemiological value. The A2075G nucleotide mutation and amino acid substitutions in L4 and L22 were detected in all erythromycin-resistant isolates (n = 5). The tetO gene was detected in 100% (n = 119) of tetracycline-resistant isolates and three of which were found to harbour the mosaic tetracycline resistance gene tetO/32/O. Two streptomycin-resistant C. jejuni isolates (isolated from the same flock) harboured ant(6)-Ib, located in a multidrug resistance genomic island, containing aminoglycoside, streptothricin (satA) and tetracycline resistance genes (truncated tetO and mosaic tetO/32/O). The ant(6)-Ie gene was identified in two streptomycin-resistant C. coli isolates. This study highlights the widespread acquisition of antimicrobial resistance determinants among chicken-associated Campylobacter isolates, through horizontal gene transfer or clonal expansion of resistant lineages. The stability of such resistance determinants is compounded by the fluidity of mobile genetic element.
