Special Issue Information

Dear Colleagues,

The gut plays a key role in the digestion and absorption of nutrients and is exposed to external factors that can challenge the health of the host. The relationship between nutrition and health is complex, dynamic, and multi-faceted. Recently, "gut health" has become even more crucial considering the efficiency and sustainability of livestock production. From a scientific point of view, however, a robust definition of gut health is still missing, indicating a lack of well-defined and measurable parameters. In general, studies on gut health in connection with nutrition and various infectious agents address scientific questions that are relevant to both animals’ and humans’ health.

This Special Issue aims to gather together innovative research on linking diet composition with gut physiology/immunology, the pathogenesis of enteric diseases, and the mode of action of feed components and animal feed additives in order to improve gut health in both animals and humans. This Special Issue also aims to present studies that show how gut health can be managed and animal performance maintained or enhanced in the absence of antibiotics by using feed additives.

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 Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English.

In this review, we link ecological adaptations of different gut microbiota members with their potential for use as a new generation of probiotics. Gut microbiota members differ in their adaptations to survival in aerobic environments. Interestingly, there is an inverse relationship between aerobic survival and abundance or potential for prolonged colonization of the intestinal tract. Facultative anaerobes, aerotolerant Lactobacilli and endospore-forming Firmicutes exhibit high fluctuation, and if such bacteria are to be used as probiotics, they must be continuously administered to mimic their permanent supply from the environment. On the other hand, species not expressing any form of aerobic resistance, such as those from phylum Bacteroidetes, commonly represent host-adapted microbiota members characterized by vertical transmission from mothers to offspring, capable of long-term colonization following a single dose administration. To achieve maximal probiotic efficacy, the mode of their administration should thus reflect their natural ecology. Full article
