Abstract This study was designed to determine the effect of early intervention with fecal microbiota transplantation combined C. butyricum and S. boulardii on anti-weaning stress capacity of piglets. 22 pregnant sows were selected in this study, 10 sows were divided into control group (CON), and 12 sows were divided into treatment group (FMT combined C. butyricum and S. boulardii, FMT+C+S). Piglets in CON were gavaged with placebo and piglets in treatment group were gavaged with bacterial solution once daily for the first 3 days after birth. Piglets were weaned at age of 28-day. To explore the effects of early intervention on weaning stress in piglets, after weaning, each group selected 65 healthy piglets to continue feeding for 4 weeks. The growth performance was measured by weekly individual weighing. ADFI during post-weaning period were measured daily. The blood biochemical markers for immunity function, intestinal barrier, and inflammation levels were determined by ELISA kits, and the indices of antioxidant ability were examined using the commercial assay kit. Isolated DNA from fecal were used for 16s rRNA amplicon sequencing to determine microbiota composition. FMT+C+S improved growth rate and decreased diarrhea rate both in sucking and post-weaning period in piglets. FMT+C+S significantly increased immunity function, intestinal barrier function, antioxidant capacity, and reduced inflammation levels in weaned piglets. FMT+C+S significantly increased the abundance of Firmicutes in feces before and after weaning (P < 0.01). In addition, at the genus level, several beneficial bacteria, such as Phascolarctobacterium, Oscillospira, Faecalibacterium, etc. were significantly enriched (P < 0.05) before weaning, and Lactobacillus, Lachnospira, Bacillus, Lysinibacillus, etc. were enriched significantly (P < 0.05) after weaning. These results suggested that early intervention with fecal microbiota transplantation combined C. butyricum and S. boulardii may be a effectively method to promote piglets growth and protect piglets from weaning stress, and even disease, through regulating gut microbiota composition.

Abstract The objective of this study was to investigate the effects of early gut colonization by fecal microbiota transplantation and probiotics intervention on growth performance, immunity function, and gut health of piglets. A total of 121 pregnant sows were divided into 6 groups with average parity of 3.66 ± 1.34. After delivery, piglets of group AB were treated with antibiotics at age of 3-day. Piglets of group CON were gavaged with PBS. The remaining four treatment groups, FMT, FMT+C, FMT+S, and FMT+C+S, the piglets were gavaged with fecal suspension, fecal suspension with C. butyricum, fecal suspension with S. boulardii, and fecal suspension with C. butyricum and S.boulardii, respectively, with the frequency of once daily in the first 3 days. All the piglets were weaned at age of 21 day. The individual body weight of piglets were weighed weekly, blood samples and fecal samples were collected weekly. At the end of study, the ADG and diarrhea rate were caculated. FMT+C+S and FMT could increased piglets 21-day-old weight (P < 0.01), and FMT+C+S could increased ADG (P < 0.05) and decreased diarrhea rate (P < 0.05). Early antibiotics exposure for health care has no positive effect on growth performance and diarrhea. FMT, FMT+S and FMT+C+S improved fecal sIgA and plasma IgG of 14-day-old piglets (P < 0.05). FMT+C+S decreased the concentration of plasma DAO and D-LA, and increased fecal MUC2 content, so that the intestinal barrier was enhanced. The early intervention of FMT combined with C. butyricum and S. boulardii reduced the abundance of E. coli, and increased the abundance of Lactobacillus, Bifidobacterium and Faecalibacterium prausnitzii. In addition, it also increases the production of intestinal short-chain fatty acids. In conclusion, these data indicated that early intervention with FMT combined C. butyricum and S. boulardii could improve the growth performance, immune responses, and gut function of sucking piglets.

Intestinal Barrier Function

Early intervention with fecal microbiota transplantation (FMT) improves the growth performance and intestinal barrier function of piglets. Accelerating intestinal oxygen concentration is beneficial for symbiotic bacterial colonization. Saccharomyces boulardii (SB) is an aerobic fungus, which may contribute to the colonization of anaerobic symbiotic bacteria by competing for oxygen. Clostridium butyricum (CB) improves intestinal barrier function and performance, via regulating the gut microbiota composition of piglets. The objective of this study was to investigate the effect of early intervention with FMT combining CB and SB on growth performance, diarrhea, and intestinal barrier function in piglets. A total of 77 litters of neonatal piglets assigned to one of six treatments, which treated with antibiotics (AB), placebo (CON), and FMT (FMT), FMT-added CB (FMT+C), FMT-added SB (FMT+S), and FMT-added CB and SB (FMT+C+S), respectively. FMT+C+S treated piglets had higher body weight (BW) and average daily gain (ADG) both in weaning and finial period, and it significantly increased the levels of fecal mucin-2 (MUC2), fecal short-chain fatty acids (SCFAs), and relative abundance of fecal Lactobacillus spp., and Bifidobacterium genus. Moreover, early intervention with FMT+C+S reduced the diarrhea rate during the experiment. FMT+C+S also decreased the level of plasma diamine oxidase (DAO) and D-lactate (D-LA), and relative abundance of fecal E. coli during the suckling period. In summary, early intervention with FMT combining CB and SB improved the growth performance, intestinal barrier function, fecal SCFAs concentration, and fecal Lactobacillus and Bifidobacterium of piglets.

Abstract Background: Gut dysbiosis has been reported to be closely associated with gout. Fecal microbiota transplantation (FMT) has been considered as an effective way to restore the balance of gut microbiota. We aimed to evaluate the effects of FMT on serum uric acid levels, gout symptoms and the intestinal barrier function in patients with acute and recurrent gout. Methods: We performed a pilot study of FMT for acute and recurrent gout. The primary outcome was the changes in serum uric acid level on day 28 post-FMT and in gout symptoms by one year. The secondary outcomes included the changes in levels of urine uric acid, diamine oxidase (DAO), D-lactic acid and endotoxin on day 28 post-FMT. The levels of DAO, D-lactic acid and endotoxin were assessed by enzyme assay. Results: Eleven patients received FMT treatment. All the patients had a reduction in serum uric acid levels after FMT treatment ( P < 0.05), accompanied with a decrease in the frequency and duration time of acute gout flares. The levels of DAO, D-lactic acid and endotoxin, reflecting the intestinal barrier function, were higher in patients with gout than in healthy donors ( P < 0.05). After FMT treatment, the levels of DAO and endotoxin decreased ( P < 0.05). Conclusions: Our findings demonstrate that FMT is effective for reducing serum uric acid levels and improving gout symptoms in patients with gout; FMT contributes to improve the impaired intestinal barrier function of the patients.

This study aimed to investigate the effects of early intervention with antibiotics and maternal fecal microbiota on ileal morphology and barrier function, and transcriptomic profiling in neonatal piglets. Piglets in the amoxicillin (AM), fecal microbiota transplantation (FMT), and control (CO) groups were orally administrated with amoxicillin solution (6.94 mg/mL), maternal fecal microbiota suspension [>109 colony forming unit (CFU)/mL], and physiological saline, respectively. Compared with the CO group, early intervention with AM or FMT significantly decreased ileal crypt depth on day 7 and altered gene expression profiles in ileum on days 7 and 21, and especially promoted the expression of chemokines (CCL5, CXCL9, and CXCL11) involved in the toll-like receptor signaling pathway on day 21. FMT changed major immune activities from B cell immunity on day 7 to T cell immunity on day 21 in the ileum. On the other hand, both AM and FMT predominantly downregulated the gene expression of toll-like receptor 4 (TLR4). In summary, both early interventions modulated intestinal barrier function and immune system in the ileum with a low impact on ileal morphology and development.

This study aimed to explore the effects of fecal microbiota transplantation (FMT) on intestinal mucosal barrier injury in mice with ulcerative colitis (UC) and to elucidate the underlying mechanisms. Dextran sodium sulfate (DSS) was administered to develop the UC mouse model. Next, the experiment was divided into a normal control group, a DSS model group, a DSS+5-amino acid salicylic acid (5-ASA) group, and a DSS+FMT group. Hematoxylin–eosin staining was used to detect pathological changes; transmission electron microscopy was used to evaluate structural changes of intestinal mucosa; enzyme-linked immunosorbent assay (ELSIA) was used to detect endotoxins; and western blotting was used to detect the expression of zonula occludens-1 (ZO-1). In the control group, the intestinal mucosa and microvilli were intact, epithelial cells were closely connected, and the intercellular space was narrow. By contrast, focal intestinal barrier defects, including shallow ulcer, local inflammatory cell infiltration, hyperplasia of connective tissue, and loss of gland structure were observed in the model group. These abnormal morphological and structural changes were ameliorated by 5-ASA and FMT. Compared with the control group, the endotoxin content increased significantly, and the ZO-1 protein expression decreased significantly in the model group (P < 0.05). By contrast, the endotoxin level decreased significantly, and the ZO-1 protein expression increased significantly in the 5-ASA group and FMT group compared with that of the model group (P < 0.05). FMT ameliorates UC by repairing the intestinal barrier function, which is likely involved in upregulating ZO-1 expression.

Background: Ulcerative colitis (UC) is a chronic non-specific inflammatory bowel disease with abdominal pain, mucus, pus and blood in the stool as the main clinical manifestations. The pathogenesis of UC is still not completely clear, and multiple factors, such as genetic susceptibility, immune response, intestinal microecological changes and environmental factors, together lead to the onset of UC. In recent years, the role of intestinal microbiota disturbances on the pathogenesis of UC has received widespread attention. Therefore, fecal microbiota transplantation (FMT), which changes the intestinal microecological environment of UC patients by transplantation of normal fecal bacteria, has attracted increasing attention from researchers. However, there are no guidelines to recommend fresh FMT or frozen FMT in the treatment of UC, and there are few studies on this. Therefore, the purpose of this study was to explore the effects of fresh and frozen FMT methods on the treatment of experimental UC models in rats.Results: Compared with the model control group, all FMT groups achieved better efficacy, mainly manifested as weight gain by the rats, improvements in fecal characteristics and blood stools, reduced inflammatory factors and normal bacterial microbiota. The efficacy of the frozen FMT group was better than that of the fresh FMT group in terms of behavior and colon length.Conclusion: FMT method supplements the gut microbiota with beneficial bacteria, such as short-chain fatty acid-producing bacteria. These bacteria can regulate intestinal function, protect the mucosal barrier and reduce harmful bacteria, thus mitigating the damage to the intestinal barrier and the associated inflammatory response, resulting in UC remission. FMT is a feasible method for treating UC, with frozen FMT having a superior therapeutic effect than that of fresh FMT.

Early Life Events

ABSTRACT Early life events can lead to multiple diseases in adulthood. Previous studies suggested that polysorbate 80 (P80) as a widely used emulsifier in pharmaceutical formulations and food industries could impair the intestinal barrier. However, whether maternal P80 (MP80) exposure could affect the long-term health of offspring remains unknown. In this study, we found that maternal P80 intake could retard intestinal development, disrupt the intestinal barrier, and cause low-grade intestinal inflammation in 3-week-old offspring. 16S rRNA sequencing and correlation analysis revealed that Mucispirillum, Clostridium XI, and Parabacteroides, which positively correlated with intestinal proliferation and differentiation, were decreased in the maternal P80 group. Interestingly, the increase in some harmful bacteria, including Proteobacteria, Helicobacteraceae, Campylobacterales, and Desulfovibrionales, persisted from the weaning period to adulthood (3 to 8 weeks). Furthermore, a fecal microbiota transplantation assay showed that the mice gavaged with feces from 3-week-old offspring of the MP80 group presented more severe intestinal inflammation and barrier disruption than the mice that received feces from the offspring of the control group. Finally, maternal P80 intake remarkably aggravated the structural disorder of intestinal crypt, increased proinflammatory factors, and exacerbated dextran sulfate sodium (DSS)-induced colitis in adulthood. Conclusively, maternal P80 intake could induce gut dysbiosis and promote colitis susceptibility in adulthood. This study provides new insights into the prevention of inflammatory bowel disease (IBD). IMPORTANCE The main findings of this research showed that maternal P80 intake could disrupt the intestinal barrier, induce gut dysbiosis, and promote colitis susceptibility in adulthood. This study will enhance understanding of the prevention of IBD.

Abstract Background Autism spectrum disorders (ASD) are associated with dysregulation of the microbiota-gut-brain axis, changes in microbiota composition as well as in the fecal, serum, and urine levels of microbial metabolites. Yet a causal relationship between dysregulation of the microbiota-gut-brain axis and ASD remains to be demonstrated. Here, we hypothesized that the microbial metabolite p-Cresol, which is more abundant in ASD patients compared to neurotypical individuals, could induce ASD-like behavior in mice. Results Mice exposed to p-Cresol for 4 weeks in drinking water presented social behavior deficits, stereotypies, and perseverative behaviors, but no changes in anxiety, locomotion, or cognition. Abnormal social behavior induced by p-Cresol was associated with decreased activity of central dopamine neurons involved in the social reward circuit. Further, p-Cresol induced changes in microbiota composition and social behavior deficits could be transferred from p-Cresol-treated mice to control mice by fecal microbiota transplantation (FMT). We also showed that mice transplanted with the microbiota of p-Cresol-treated mice exhibited increased fecal p-Cresol excretion, compared to mice transplanted with the microbiota of control mice. In addition, we identified possible p-Cresol bacterial producers. Lastly, the microbiota of control mice rescued social interactions, dopamine neurons excitability, and fecal p-Cresol levels when transplanted to p-Cresol-treated mice. Conclusions The microbial metabolite p-Cresol induces selectively ASD core behavioral symptoms in mice. Social behavior deficits induced by p-Cresol are dependant on changes in microbiota composition. Our study paves the way for therapeutic interventions targeting the microbiota and p-Cresol production to treat patients with ASD.

Abstract Objective To investigate the impact of microecological preparation combined with modified low-carbon diet on the glucolipid metabolism and cardiovascular complication in obese patients. Methods From August 2017 to July 2020, 66 obese patients were recruited, and administrated with an modified low-carbon diet with (group A) or without (Group B) microecology preparation and a balanced diet in control group (group C) for 6 months. Meanwhile, 20 volunteers administrated with a balanced diet were recruited as the healthy control group (group D). Results After 6-month intervention, obese subjects in group A and B showed significant improvement of body and liver fat mass, reduction of serum lipid levels, intestinal barrier function markers, insulin resistance index (IRI), high blood pressure (HBP) and carotid intima thickness, as compared with subjects in group C. More importantly, subjects in group A had better improvement of vascular endothelial elasticity and intimal thickness than subjects in group B. However, these intervention had no effect on carotid atherosclerotic plaque. Conclusion Administration of microecological preparation combined with modified low-carbon diet had better improvement of intestinal barrier function, glucose and lipid metabolism, and cardiovascular complications than low-carbon diet in obese patients, but the effect of a simple low-carb diet on carotid atherosclerotic plaque need to be further addressed.

The Impact

Non-alcoholic fatty liver disease (NAFLD) is an increasing cause of chronic liver illness associated with obesity and metabolic disorders, such as hypertension, dyslipidemia, or type 2 diabetes mellitus. A more severe type of NAFLD, non-alcoholic steatohepatitis (NASH), is considered an ongoing global health threat and dramatically increases the risks of cirrhosis, liver failure, and hepatocellular carcinoma. Several reports have demonstrated that liver steatosis is associated with the elevation of certain clinical and biochemical markers but with low predictive potential. In addition, current imaging methods are inaccurate and inadequate for quantification of liver steatosis and do not distinguish clearly between the microvesicular and the macrovesicular types. On the other hand, an unhealthy status usually presents an altered gut microbiota, associated with the loss of its functions. Indeed, NAFLD pathophysiology has been linked to lower microbial diversity and a weakened intestinal barrier, exposing the host to bacterial components and stimulating pathways of immune defense and inflammation via toll-like receptor signaling. Moreover, this activation of inflammation in hepatocytes induces progression from simple steatosis to NASH. In the present review, we aim to: (a) summarize studies on both human and animals addressed to determine the impact of alterations in gut microbiota in NASH; (b) evaluate the potential role of such alterations as biomarkers for prognosis and diagnosis of this disorder; and (c) discuss the involvement of microbiota in the current treatment for NAFLD/NASH (i.e., bariatric surgery, physical exercise and lifestyle, diet, probiotics and prebiotics, and fecal microbiota transplantation).
