“…There is a study [ 24 ] which showed that the amount of prausnitzii was inversely associated with the activity of inflammatory bowel disease and colon cancer. Some bifidobacterium [ 25 ] strains are considered to produce beneficial bacteria to the body, less content in the intestine but have a significant impact on human health. Its multiple biological functions have been reported, such as immune regulation, antitumor activity, anti-inflammation, antiaging, antiaging, reducing blood lipid, etc.…”

Objective. To investigate the influence of long-term night shift nurses on the composition. Methods. The feces of 30 night shift nurses (test group) and 30 day shift nurses (control group) over 1 year were collected, and double-end sequencing based on bacterial 16S rDNA V3 + V4 and fungal 18S rDNA V3 + V4 was used to determine the differences by OTU clustering, diversity, flora abundance, and differential analysis. The results of 60 samples were sequenced for a total of 3, 052. There were 418 high-quality sequences, each sample produced an average of 50, 874 high-quality sequences. The OTU cluster analysis revealed that the number of OTUs was 365. The number of day-shift shift OTUs was 362. There was no significant difference ( p < 0.05 ). There was no significant statistical difference in the Chao, Ace, Shan’non, and Simpson index between the 2 groups ( P > 0.05 ). Differential analysis of gut microflora between 2 groups showed that at the phylum level, the relative abundance of firmicutes in long-term night shift nurses was higher than in day shift nurses. However, the relative abundance of bacteroidetes was lower than that of white shift nurses (all p < 0.05 ). At the genus level, long-term night shift nurses’ Bacteroides, Faecacterium, and Bifidobacterial were lower than that of white shift nurses ( p < 0.05 ). However, the relative abundance of Prevotella and Megomonas was higher than that of white shift nurses (all p < 0.05 ). Conclusion. There are differences between night shift nurses, which lead to a decrease in intestinal probiotic flora and increased conditional pathogenic flora. Nursing managers should improve the intestinal flora change of night shift nurses through reasonable scheduling and dietary regulation.

“…Bifidobacteria, as a probiotic, plays important roles in immune regulation, anti-tumour, anti-pathogenicity and anti-inflammation, and can produce acetate to protect the enteropathogenic infection. (Fukuda et al 2011;Luo et al 2018). Cupriavidus can catabolize intestinal amino acid by secreting various enzymes (Ueatrongchit and Asano 2011).…”

Aim: The study was conducted to investigate the effects of dietary Bacillus subtilis (BS) DSM 32315 on the intestinal microbiota composition and metabolites of weaned pigs. Methods and Results: Sixty-four piglets were allocated to two groups (control and BS), each group including eight replicates with four piglets. Dietary BS DSM 32315 increased (P < 0Á05) the abundances of jejunal Leucobacter and Cupriavidus, ileal Thermus, Coprococcus and Bifidobacterium, as well as colonic Succiniclasticum; and increased the concentrations of ileal straight-chain fatty acids, colonic propionate, branched-chain fatty acids (BCFAs), and tyramine, but decreased (P < .05) the colonic indole concentration. The ileal and colonic microbial community structure tended to cluster into two groups. LEfSe analysis identified five microbial biomarkers in jejunum and eight biomarkers in ileum in the BS group, and three biomarkers in colon in the control group. The ileal Bifidobacterium abundance was positively correlated (P < 0Á05) with isovalerate concentration, while the colonic Actinobacteria and Lactobacillus abundances were negatively correlated (P < 0Á05) with indole concentration. Conclusion: These findings suggest that dietary supplementation with BS DSM 32315 could alter the diversity, composition, and metabolites of intestinal microbiota in weaned piglets. Significance and Impact of the Study: Weaned piglets are often accompanied with impaired gastrointestinal tract and intestinal disorder affecting their growth. This study demonstrated that dietary BS DSM 32315 presented a beneficial role in gut health via regulating intestinal microbiota composition and metabolites.

“…Particularly, Lactobacillus and Bifidobacterium , which played important roles in maintaining intestinal homeostasis and fortifying the intestinal mucus layer ( 27 , 28 ) in the present study were significantly proliferated in HF treatment. Higher abundance of cecal Lactobacillus positive regulated a better feed efficiency ( 2 ), while increased Bifidobacterium correlated with reduced adiposity and levels of microbe-derived inflammatory molecules ( 29 ).…”

Background: Geese are conventionally considered to be herbivorous, which could also be raised with concentrate feeding diets without green grass because of the similar gastrointestinal tract with other poultry. However, the geese gut microbiota profiles and their interactions with epithelial cells are still of limited study. Flavonoids were well-documented to shape gut microbiota and promote epithelial barrier functions individually or cooperatively with other metabolites. Therefore, in the present study, honeycomb flavonoids (HF) were supplemented to investigate the effects on growth performances, intestinal development, and gut microbiome of geese.Material and Methods: A total of 400 1-day-old male lion-head geese with similar birth weight (82.6 ± 1.4 g) were randomly divided into five treatments: the control treatment (CON) and the HF supplementation treatments, HF was supplemented arithmetically to increase from 0.25 to 1%. Growth performance, carcass performances, and intestines' development parameters were measured to determine the optimum supplement. Junction proteins including ZO-1 and ZO-2 and cecal microbiota were investigated to demonstrate the regulatory effects of HF on both microbiota and intestinal epithelium.Results: Results showed that 0.5% of HF supplement had superior growth performance, carcass performance, and the total parameters of gastrointestinal development to other treatments. Further research showed that tight junction proteins including ZO-1 and ZO-2 significantly up-regulated, while Firmicutes and some probiotics including Clostridiales, Streptococcus, Lachnoclostridium, and Bifidobacterium, remarkably proliferated after HF supplement. In conclusion, HF supplement in concentrate-diet feeding geese effectively increased the growth performances by regulating the gut microbiota to increase the probiotic abundance to promote the nutrient digestibility and fortify the epithelial development and barrier functions to facilitate the nutrient absorption and utilization.
