“…Host factors include variation in genetic predisposition to diseases (across multiple loci) as well as specific polymorphisms in microbial recognition pathways that can influence colonization and its biological effects 16 . A number of environmental factors, including mode of delivery and early feeding, antibiotics, disease status and adult diet, can influence the human microbiome and possibly the effects of prebiotic supplementation [122][123][124][125] .…”

In December 2016, a panel of experts in microbiology, nutrition and clinical research was convened by the International Scientific Association for Probiotics and Prebiotics to review the definition and scope of prebiotics. Consistent with the original embodiment of prebiotics, but aware of the latest scientific and clinical developments, the panel updated the definition of a prebiotic: a substrate that is selectively utilized by host microorganisms conferring a health benefit. This definition expands the concept of prebiotics to possibly include non-carbohydrate substances, applications to body sites other than the gastrointestinal tract, and diverse categories other than food. The requirement for selective microbiota-mediated mechanisms was retained. Beneficial health effects must be documented for a substance to be considered a prebiotic. The consensus definition applies also to prebiotics for use by animals, in which microbiota-focused strategies to maintain health and prevent disease is as relevant as for humans. Ultimately, the goal of this Consensus Statement is to engender appropriate use of the term 'prebiotic' by relevant stakeholders so that consistency and clarity can be achieved in research reports, product marketing and regulatory oversight of the category. To this end, we have reviewed several aspects of prebiotic science including its development, health benefits and legislation

“…This early colonization is critical for the development of the immune system. This rapid colonization process and the microbial composition of the neonatal gut are influenced by a number of factors including antibiotic use, diet, mode of delivery, environmental factors, and the maternal microbiota (Adlerberth and Wold, 2009;Marques et al, 2010). The microbiota of formula-fed infants has been reported to be more diverse than breast-fed infants, containing higher proportions of Bacteroides, Clostridium, and Enterobacteriaceae.…”

There is now a large volume of evidence to support the view that the immune system is a key communication pathway between the gut and brain, which plays an important role in stress-related psychopathologies and thus provides a potentially fruitful target for psychotropic intervention. The gut microbiota is a complex ecosystem with a diverse range of organisms and a sophisticated genomic structure. Bacteria within the gut are estimated to weigh in excess of 1 kg in the adult human and the microbes within not only produce antimicrobial peptides, short chain fatty acids, and vitamins, but also most of the common neurotransmitters found in the human brain. That the microbial content of the gut plays a key role in immune development is now beyond doubt. Early disruption of the host-microbe interplay can have lifelong consequences, not just in terms of intestinal function but in distal organs including the brain. It is clear that the immune system and nervous system are in continuous communication in order to maintain a state of homeostasis. Significant gaps in knowledge remain about the effect of the gut microbiota in coordinating the immune-nervous systems dialogue. However, studies using germ-free animals, infective models, prebiotics, probiotics, and antibiotics have increased our understanding of the interplay. Early life stress can have a lifelong impact on the microbial content of the intestine and permanently alter immune functioning. That early life stress can also impact adult psychopathology has long been appreciated in psychiatry. The challenge now is to fully decipher the molecular mechanisms that link the gut microbiota, immune, and central nervous systems in a network of communication that impacts behavior patterns and psychopathology, to eventually translate these findings to the human situation both in health and disease. Even at this juncture, there is evidence to pinpoint key sites of communication where gut microbial interventions either with drugs or diet or perhaps fecal microbiota transplantation may positively impact mental health.

AIMS: we performed this case-control observational study to evaluate the effects of early administration of Lactobacillus reuteri DSM 17938 on microbial composition in infants' gastrointestinal tract. METHODS: early fecal microbiota composition was analyzed by using selective and differential cultural methods. Genomic DNA from positive Escherichia coli and Cronobacter sakazakii colonies was extracted and DNA was processed by multiplex PCR assay. RESULTS: fecal samples of 30 hospitalized infants who previously received probiotics and 30 not receiving probiotics were analyzed. We find that the two groups showed differences in gut microbial strains composition and richness. Infant treated with probiotics have a lower total anaerobic gramnegative counts (p=0.03) and a higher total anaerobic gram-positive counts (p=0.02). Enterobacteriaceae and enterococci were significantly higher (p=0.04) in the control group. No significant differences were observed for total aerobic counts, lactobacilli and bifidobacteria. C. sakazaki was found only in one infant recruited in the control group. Infants not previously treated with probiotics showed a higher colonization by diarrheagenic E. coli (EPEC) (p=0.04). CONCLUSIONS: our findings enhanced our understanding of the effects of probiotics on gut health in pediatric subjects. Early administration of L.reuteri in infancy could improve gut health by reducing pathogens colonization. Our trial underlines the efficacy of an early probiotic administration in improving gut health in infancy.Informed consent was obtained from each child's parent.The study has been approved by a research ethics committee.There are no prior publications or submissions with any overlapping information, including studies and patients.These data have not been published previously and are not under consideration for publication by any other journal. The manuscript has not been and will not be submitted to any other journal while it is under consideration by Clinica Chimica Acta Journal.All authors have read and approved the version of the article being submitted.No an honorarium, grant, or other form of payment was given to anyone to produce the manuscript.All authors declare no conflict of interest.No affiliations with or financial involvement in any organization or entity with a direct financial interest in the subject matter or materials of the research discussed in the manuscript were present.
