Mammals contain resident fungal intestinal populations that influence disease susceptibility.
To investigate the relationship of Lgr5lowKi67− cells with the proposed secretory precursors and related intestinal populations, we used the GSEA analysis (Fig 6C).
Similarly, the inclusion of DF in piglet diets enhanced intestinal populations of Lactobacilli spp. and reduced the incidence and severity of diarrhea (Edwards, 1996).
Prebiotics, e.g. indigestible fibers fermented by the intestinal microbiota, such as polymers of fructose or galactose, have shown promising results in increasing the intestinal population of beneficial bacteria such as bacteria belonging to the genera Lactobacillus and Bifidobacterium (Roberfroid et al. 2010).
As evidenced by early comparisons of germ-free and conventional animals, the intestinal population of bacteria has a marked effect on intestinal immune functions [32] [34].
The most abundant intestinal population is the intraepithelial lymphocytes (IELs) V γ5+, whose expression depends on thymic maturation driven by IL-15 [ 124].
Because of lactobacilli are the predominant species vaginally, they can be easily overgrown by the predominant rectal bacteria as they represent about 0,01% of the overall cultivable bacterial intestinal population [ 39, 40].
This will coincide in time with alterations of the intestinal population, in terms of a less diversified faecal coliform flora, which is induced by the weaning [ 26, 30, 32, 22].
Ruminant-associated marker concentrations were strongly correlated with total intestinal Bacteroidetes populations and with each other, indicating that the detected ruminant-associated populations seem to be part of the intestinal core microbiome of ruminants worldwide.
Microarray analysis was used to compare the transcriptional profiles of K-cells from the duodenum (K+), L cells from the upper 10 cm of the SI (L+) or colon (LC+), control (nonfluorescent) intestinal cell populations (K−, L−, and LC−), and pancreatic α- and β-cells, using mRNA from FACS-sorted cell populations from GIP-Venus or GLU-Venus mice (13, 14).
An experiment was conducted to investigate the effect of dietary supplementation of xylo-oligosaccharides (XOS) on growth performance, meat quality, immune functions, duodenal morphology and intestinal microbial populations of broilers fed a conventional corn-soybean meal basal diet.
