Special Issue Information
Dear Colleagues,
In recent years, the study of microbiota has revolutionized most fields of research in the biological sciences. Microbiota have a fundamental role in both human and animal health and disease. In the specific case of gut microbiota, they act as a second barrier against colonization by pathogens, regulate the development and maturation of the immune system, provide beneficial metabolites for host nutrition, and, more importantly, have a functional influence on each component that maintains intestinal homeostasis. While healthy microbiota can promote resistance to colonization by pathogenic species, dysbiosis or a microbial imbalance may promote the expansion or enhanced virulence of pathogenic populations. As a classical example, antibiotics can modify taxonomic, genomic, and functional features of gut microbiota, resulting in colonization by such pathogens as Clostridium difficile. In addition, saccharolytic members of the microbiota can be liberated from sugars in mucus layers as sialic acid or fucose that can be used by Salmonella typhimurium as a source of energy, promoting its growth. However, healthy microbiota also have mechanisms for protection. For example, short-chain fatty acids produced by the bacterial metabolism can inhibit the growth of pathogens and enhance the production of antimicrobial peptides by immune cells. In contrast, bacteriocins and bacteriophages can inhibit the growth of specific bacterial groups.
This Special Issue welcomes original research articles and literature reviews on interactions between pathogens and microbiota or specific components of microbiota, such as bacterial metabolites. This Special Issue also welcomes studies on the development of new strategies for modulating microbiota to make them resistant to bacterial infections.

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. International Journal of Environmental Research and Public Health 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 2500 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.
