“…Aside from Klebsiella, mainly saccharolytic and amylolytic genera, such as Anaerovibrio, Selenomonas, Lactobacillus and Coriobacteriaceae, benefitted from TGS in ileal digesta. These taxa produce lactate, acetate and succinate as fermentation end-products (36)(37)(38) , which would correspond to the present results for fermentation acids in the ileum. A TGS-related increase in Klebsiella and Coriobacteriaceae, however, needs to be critically monitored in human studies as both taxa may act pro-inflammatory and have been linked to inflammatory bowel disease and other autoimmune diseases (24,39) .…”

Resistant starch can alter the intestinal nutrient availability and bulk of digesta, thereby modulating the substrate available for microbial metabolic activity along the gastrointestinal tract. This study elucidated the effect of transglycosylated starch (TGS) on the retention of digesta in the upper digestive tract, ileal flow and hindgut disappearance of nutrients, and subsequent bacterial profiles in pigs. Fourteen ileal-cannulated growing pigs were fed either the TGS or control (CON) diet in a complete crossover design. Each period consisted of a 10-d adaptation to the diets, followed by 3-d collection of faeces and ileal digesta. Consumption of TGS decreased the retention of digesta in the stomach and small intestine, and increased ileal DM, starch, Ca and P flow, leading to enhanced starch fermentation in the hindgut compared with CON-fed pigs. TGS increased ileal and faecal total SCFA, especially ileal and faecal acetate and faecal butyrate. Gastric retention time positively correlated to Klebsiella, which benefitted together with Selenomonas, Lactobacillus, Mitsuokella and Coriobacteriaceae from TGS feeding and ileal starch flow. Similar relationships existed in faeces with Coriobacteriaceae, Veillonellaceae and Megasphaera benefitting most, either directly or indirectly via cross-feeding, from TGS residuals in faeces. TGS, in turn, depressed genera within Ruminococcaceae, Clostridiales and Christensenellaceae compared with the CON diet. The present results demonstrated distinct ileal and faecal bacterial community and metabolite profiles in CON- and TGS-fed pigs, which were modulated by the type of starch, intestinal substrate flow and retention of digesta in the upper digestive tract.

“…We further found significant differences in the phylum of Actinobacteria and the family of Coriobacteriaceae between individuals with BD and HCs. Actinobacteria and Coriobacteriaceae are common inhabitants of the GI‐tract involved in lipid metabolism and shown to correlate with cholesterol levels, which could be the reason for finding them more abundant in the BD group.…”

“…Consumption of dietary fiber improves glucose metabolism, which is associated with increased abundance of Prevotella (Kovatcheva-Datchary et al 2015). Furthermore, the abundance of the genus Collinsella (phylum Actinobacteria) is positively correlated with circulating insulin, which affects host metabolism by altering cholesterol absorption, decreasing liver glycolysis, and increasing triglyceride synthesis (Clavel et al 2014). Increased abundance of Collinsella has also been observed in overweight and obese pregnant women after low dietary fiber intake (Gomez-Arango et al 2018).…”

Pyrodextrin (PD) is prepared from starch by heat treatment and is resistant to amylase. We hypothesized that PD might have prebiotic potential affecting the microbiota composition, because it contains a non-digestible portion that may behave as dietary fiber. This study investigated the effects of PD supplementation on growth performance, gut morphology, short-chain fatty acids (SCFAs), and the bacterial community in weaned piglets receiving dietary supplementation of 0.5% PD. The piglets in the PD (treated) groups showed greater antioxidant capacity and feed efficiency (P < 0.05), as well as improved intestinal morphology in comparison with the piglets in the weaned (control) group. Gut microbiota profiles were assessed through 16S rRNA sequencing on the ileum contents and feces of early weaned piglets. Several genus-level enrichments and depletions were observed in response to PD treatment. Of note, PD supplementation decreased the relative abundance of pathogenic organisms, including Defluviicoccus and Gardnerella, while markedly increasing that of commensal bacteria (genera Psychrobacter and Prevotella), which have important roles in nutrient absorption and immune response regulation. The most notable effect in the PD treatment groups was increased production of SCFAs in the feces of PD-treated weaned piglets. Correlation analysis revealed that the improvement in SCFAs was positively correlated with the increase in SCFA-producing bacteria. Overall, this study provides a more comprehensive understanding of the effects of PD supplementation on the fecal microbial community and the modulation of SCFA production in early weaned piglets, thus indicating that PD can be used to alleviate weaning stress in piglets.
