The defining effect of prebiotics is to stimulate selectively the growth of bifidobacteria and lactobacilli in the gut and, thereby, increase the body's natural resistance to invading pathogens. Prebiotic carbohydrates may also have additional, less specific, benefits because they are fermented in the large intestine. The prebiotic carbohydrates that have been evaluated in humans at the present time largely consist of fructans or galactans. There is consistent evidence from in vitro and in vivo… 
The Utilisation of Prebiotics and Synbiotics in Dogs
TLDR
An overview of the scientific literature dealing with the use of prebiotics and synbiotics in the canine species is presented, finding short-chain fructooligosaccharides and oligofructose seem to be the most effective in modulating the canine intestinal ecosystem and improving intestinal absorption of minerals but with little or no effect on canine immune system.
Probiotics, prebiotics, and synbiotics.
TLDR
A prebiotic is "a selectively fermented ingredient that allows specific changes, both in the composition and/or activity in the gastrointestinal microflora that confers benefits upon host well being and health", whereas synergistic combinations of pro- and prebiotics are called synbiotics.
Effects of Probiotics, Prebiotics, and Synbiotics on Human Health
TLDR
This paper provides a review of available information and summarises the current knowledge on the effects of probiotics, prebiotics, and synbiotics on human health, and verified study results proving their efficacy in human nutrition are presented.
Effects of prebiotics, probiotics and synbiotics in the diet of young pigs
TLDR
Overall, it was concluded that synbiotics, a combination of multi-strain probiotics and oligofructose, can positively affect performance especially feed intake, and can improve the gut health.
Potential of fructooligosaccharide prebiotics in alternative and nonconventional poultry production systems.
TLDR
As more detailed and precise studies are done with nonconventional poultry, it is likely that structurally distinct prebiotics will influence not only the gastrointestinal tract microbiota differently, but potentially interact directly and/or indirectly with the bird host in distinguishable patterns as well.
Review article: bifidobacteria as probiotic agents – physiological effects and clinical benefits
TLDR
The traditional use of bifidobacteria in fermented dairy products and the GRAS status of certain strains attest to their safety, and some strains show high gastrointestinal survival capacity and exhibit probiotic properties in the colon.
Prebiotic properties of epilactose.
TLDR
Results clearly indicate that epilactose is a promising prebiotic, and it is shown that cellobiose 2-epimerase converted lactose in cow milk and a spray-dried ultrafiltrate of cheese whey to epilACTose.
Prebiotic Functional Food Supplements Enhance Gut Health
TLDR
Maintenance of normal architecture and increased adherence of lactobacilli to colon was observed in formulation groups, and this study may be useful to develop novel multifunctional supplements.
Lactobacilli in the porcine intestine: from composition to functionality
TLDR
The addition of fermentable carbohydrates to the diet of weaning piglets was found to enhance the stability and diversity of the microbiota in the large intestine of piglets, and to stimulate the growth of strains closely related to Lactobacillus amylovorus.

Effects of Fructooligosaccharides on Intestinal Flora and Human Health
TLDR
Clinical studies showed that fructooligosaccharides administration improved the intestinal flora, with subsequent relief of constipation, improved blood lipids in hyperlipidemia , and suppressed the production of intestinal putrefactive substances.
Regulatory effects of bifidobacteria on the growth of other colonic bacteria.
TLDR
Results show that bifidobacteria are able to exert more than one mechanism of inhibition, which may be of some importance with regard to protection against gastroenteritis.
Effects of the in vitro fermentation of oligofructose and inulin by bacteria growing in the human large intestine.
TLDR
Bacterial growth data showed that oligofructose and inulin exerted a preferential stimulatory effect on numbers of the health-promoting genus Bifidobacterium, whilst maintaining populations of potential pathogens (Escherichia coli, Clostridium) at relatively low levels.
Administration of transgalacto-oligosaccharides increases fecal bifidobacteria and modifies colonic fermentation metabolism in healthy humans.
TLDR
Prolonged administration of transgalacto-oligosaccharides, at a dose which does not induce digestive symptoms, increases the number of bifidobacteria and alters the fermentative activity of colonic flora in humans.
Fate of fructo-oligosaccharides in the human intestine
TLDR
It is concluded that fructo-oligosaccharides added to the diet of young Western subjects are fully metabolized in the large intestine, and the level of fermentation seem to be dose-dependent.
Effects of Administration of Galactooligosaccharides on the Human Faecal Microflora, Stool Weight and Abdominal Sensation
TLDR
Results of this study show that galactooligosaccharides are a superior growth-promoting factor for bifidobacteria, and, moreover, have the ability to increase the multiplication of lactobacilli in the human intestinal microflora.
Effects of inulin and lactose on fecal microflora, microbial activity, and bowel habit in elderly constipated persons.
TLDR
Inulin showed a better laxative effect than lactose and reduced functional constipation with only mild discomfort and SCFAs showed a slight trend toward higher molar ratios of acetate to butyrate in response to the intake of lactose or inulin.
Effect of fructo-oligosaccharides on intestinal microflora.
TLDR
In the experiment with 23 patients, improvement of fecal microflora was observed by oral administration of fructo-oligosaccharides 8 g per day for two weeks: the population of bifidobacteria in feces increased about 10 times compared before the administration; average pH of stool showed 0.3 lower than that before administration.
Cereal fructans: in vitro and in vivo studies on availability in rats and humans.
TLDR
In vivo studies of the small intestine in rats showed that the rate of disappearance of fructans was lower than that of mannose, which is known to be absorbed through passive diffusion.
