Special Issue Information

Dear Colleagues,

Antibiotic resistance presents a formidable challenge, affecting the health of both animals and humans. As we grapple with the rising threat of antibiotic resistance in veterinary microbiology, it is imperative to immerse ourselves in this pivotal research domain. Embracing the core tenets of the One Health concept, which recognizes the interconnectedness of human, animal and environmental health, we extend a warm invitation to you. We invite your active participation in this critical research endeavor, emphasizing the integral role of a holistic approach to address this pressing global concern.

This Special Issue is dedicated to advancing our understanding of antibiotic resistance within the realm of veterinary microbiology. Potential research areas may include, but are not limited to:

  • Mechanisms and patterns of antibiotic resistance in veterinary settings;
  • Impact of antibiotic use on animal health and welfare;
  • Zoonotic aspects of antibiotic resistance;
  • Antibiotic resistance in the context of One Health;
  • Strategies for responsible antibiotic use in veterinary practices;
  • Publica health implications of veterinary antibiotic resistance.

We encourage contributors to explore these themes and beyond, fostering a diverse range of perspectives to enrich our collective understanding of combatting antibiotic resistance in veterinary microbiology. In this Special Issue, original research articles and reviews are welcome.

I look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Antibiotics and antibiotic growth promoters have been extensively employed in poultry farming to enhance growth performance, maintain bird health, improve nutrient uptake efficiency, and mitigate enteric diseases at both sub-therapeutic and therapeutic doses. However, the extensive use of antimicrobials in poultry farming has led to the emergence of antimicrobial resistance (AMR) in microbial reservoirs, representing a significant global public health concern. In response, non-antibiotic dietary interventions, such as yeast mannan-rich fraction (MRF), have emerged as a promising alternative to modulate the gut microbiota and combat the AMR crisis. This study investigated whether a yeast mannan-rich fraction containing feed supplement impacted the performance of laying hens, their microbiomes, and the associated carriage of antimicrobial resistance genes under commercial conditions. High-throughput DNA sequencing was utilised to profile the bacterial community and assess changes in the antibiotic resistance genomes detected in the metagenome, the “resistome”, in response to MRF supplementation. It was found that supplementation favourably influenced laying hen performance and microbial composition. Notably, there was a compositional shift in the MRF supplemented group associated with a lower relative abundance of pathobionts, e.g., Escherichia, Brachyspira and Trueperella, and their AMR-encoded genes, relative to beneficial microbes. Overall, the findings further demonstrate the ability of prebiotics to improve laying hen performance through changes associated with their microbiome and resistome. Full article
