Special Issue Information

Dear Colleagues,

Antibiotic resistance represents a global challenge threatening public health, food safety, and environmental sustainability. The complex interplay between the clinical, environmental, and veterinary domains requires an integrated approach to understanding and mitigating the transmission of resistance mechanisms.

This Special Issue will focus on the study and prevention of antibiotic resistance transmission from a One Health perspective. Emphasizing a holistic approach, this Special Issue will uncover the pathways by which resistance mechanisms spread, particularly from non-pathogenic environmental strains to potentially human-pathogenic strains. This knowledge is critical in designing innovative interventions and policies aimed at controlling the dissemination of resistance across ecosystems.

Aims and Scope:

This Special Issue aligns with the journal's mission to advance knowledge in antibiotic resistance. Our aim is to collect high-quality original research and review articles that address key aspects of antibiotic resistance transmission and prevention. Submissions that offer interdisciplinary insights into the One Health paradigm are particularly welcome.

Suggested themes and article types for submission:

  • The mechanisms behind antibiotic resistance emergence and spread in natural environments;
  • The role of environmental reservoirs in transmitting resistance to human pathogens;
  • The surveillance and detection of resistance genes in clinical, environmental, and veterinary settings;
  • Strategies for mitigating the spread of resistance in integrated ecosystems;
  • Case studies showcasing successful One Health interventions;
  • Policy and education frameworks to support One Health approaches to resistance prevention;
  • New methods and techniques advancing knowledge in, and evaluating the impact of, human activities in relation to the expression of antibiotic resistance in microbial communities.

We look forward to receiving your contributions and engaging in meaningful discussions on this pressing issue.

Background/Objectives: Antimicrobial resistance (AMR) poses a significant threat to public health, food security, and sustainable livestock production. Despite increasing concern, AMR remains poorly studied in cuniculture, particularly in regions where rabbit farming is predominantly small-scale and household-based. This study aimed to assess the prevalence and diversity of antimicrobial resistance genes (ARGs) in rabbit farms in northeastern Ukraine. Methods: A total of 100 fecal samples were collected from clinically healthy rabbits housed in two farms and one vivarium. DNA was extracted and analyzed using real-time PCR targeting 21 ARGs associated with resistance to major antibiotic classes, including tetracyclines, sulfonamides, β-lactams, macrolides, quinolones, carbapenems, and multidrug efflux systems. Results: A diverse and widespread resistome was identified. The most prevalent genes included sul1 (96%), blaTEM (95%), tetM (94%), and ermB (93%). AcrB (78%) and qnrS/oqxB (approximately 67%) were also frequently detected. Carbapenemase genes (blaKPC, blaNDM, blaVIM) were identified in 6% of samples, despite limited veterinary use of carbapenems. Notably, 96% of samples harbored ARGs from three or more antibiotic classes, indicating a high potential for multidrug resistance. Conclusions: The findings demonstrate a high prevalence and diversity of ARGs in rabbit farming systems in northeastern Ukraine. The presence of clinically significant resistance genes, including those conferring carbapenem resistance, underscores the urgent need for targeted AMR surveillance and improved antibiotic stewardship in cuniculture, particularly in regions with minimal regulatory oversight of antimicrobial use.

Background/Objectives: Salmonella enterica subsp. enterica serovar Enteritidis (S. Enteritidis) is a major pathogen associated with poultry products, and the rise of antimicrobial-resistant strains has intensified the need for effective natural control strategies. Essential oils (EOs) are recognized for their antimicrobial potential, but their volatility, instability, and risk of toxicity at high concentrations limit their practical application. Therefore, the objective of this study was to evaluate the antimicrobial efficacy of EOs in broilers infected with S. Enteritidis and to characterize potential synergistic or antagonistic interactions between the oils. Methods: To achieve this, the oils were first assessed through Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), and Fractional Inhibitory Concentration (FIC) assays, and the most effective ones against S. Enteritidis were selected. These selected oils were then microencapsulated and incorporated into the broiler feed for the in vivo assay. Results: The encapsulated formulation retained key bioactive compounds and significantly reduced bacterial shedding and intestinal colonization when administered to broilers experimentally infected with S. Enteritidis. Broilers receiving the optimized half-dose supplementation exhibited a 36% reduction in fecal shedding and a 4 log10 decrease in cecal bacterial counts compared to untreated controls. A transient reduction in liver colonization was also observed, while feed intake remained unaffected. Conclusions: These findings demonstrate that microencapsulated EOs can serve as an effective natural strategy to control S. Enteritidis in poultry. The results support the broader application of lipid-based encapsulation technologies for improving the functional performance of phytobiotics in animal production. Full article
