Special Issue Information

Dear Colleagues,

This Special Issue is the continuation of our previous Special Issue "Microbiota and Microbiomes in Plants, Animals and Environment: A One Heath Perspective".

Productivity and health are linked to inputs and environmental conditions, which are key factors in shaping the compositional structure and function of host microbiota while influencing their environment. Accordingly, agricultural farming, food processing, and clinical practices are accompanied by the emission of and exposure to environmental pollutants. Pathogens living in changing environmental conditions (e.g., temperature, precipitation, humidity, CO2, ammonium concentrations, greenhouse gases, etc.) must adapt and evolve. Their virulence potential may spread through horizontal gene transfer, a major mechanism of the antimicrobial resistance (AMR) gene acquisition, which increases with temperature. Therefore, health, climate change, and AMR are interlinked and should be addressed to protect humans, livestock, and plants. A “One Health approach,” using “omics” in the control and surveillance under public health policies, is needed to understand and mitigate the impacts of climate change on the environment, the evolution of microbiomes, and their relationships with health and productivity.

Thus, this Special Issue entitled “Microbiota and Microbiomes in Plants, Animals and Environment: A One Heath Perspective—Second Edition”. Original research or review articles and short communications dealing with microbiomes in humans, the environment, plants, farm animals, and food production are welcome.

We look forward to receiving your manuscript for review.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Alternative feed additives are being investigated due to the restriction of antibiotics use to decrease antimicrobial resistance (AMR) in food-producing animals. This study investigated the effects of dietary American cranberry (Vaccinium macrocarpon) and wild blueberry (V. angustifolium) pomaces on the cecal microbiota and resistome profiles as well as the short-chain fatty acid levels. Male broiler chickens Cobb500 were fed a basal diet with either 55 ppm bacitracin methylene disalicylate (BMD); 0.5% (CRP0.5) and 1% (CRP1) cranberry pomace; and 0.5% (LBP0.5) and 1% (LBP1) lowbush blueberry pomace with or without a multienzyme mixture (ENZ). The results showed that at 21 days of age, the total coliform counts decreased in the CRP0.5-fed birds compared to BMD (p < 0.05). The use of pomace significantly increased the abundance of Lactobacillus and Bacteroides regardless of ENZ, while CRP decreased the Proteobacteria phylum abundance. In-feed ENZ tended to increase the relative abundance of genes conferring aminoglycoside resistance. Treatment with CRP0.5 decreased the abundance of cepA genes encoding for macrolide (MACROLIDE) and lincomycin (InuD) resistance while increasing those for tetracycline (tetO and tetX) resistance. These results showed, for the first time, the potential of the studied enzymes in influencing berry pomace’s effects on antimicrobial resistance gene profiles in broilers. Full article
