Clostridium butyricum MIYAIRI 588 Modifies Bacterial Composition under Antibiotic-Induced Dysbiosis for the Activation of Interactions via Lipid Metabolism between the Gut Microbiome and the Host.

ABSTRACT: The gut microbiome is closely related to gut metabolic functions, and the gut microbiome and host metabolic functions affect each other. Clostridium butyricum MIYAIRI 588 (CBM 588) upregulates protectin D1 production in host colon tissue following G protein-coupled receptor (GPR) 120 activation to protect gut epithelial cells under antibiotic-induced dysbiosis. However, how CBM 588 enhances polyunsaturated fatty acid (PUFA) metabolites remains unclear. Therefore, we focused on the metabolic function alterations of the gut microbiome after CBM 588 and protectin D1 administration to reveal the interaction between the host and gut microbiome through lipid metabolism during antibiotic-induced dysbiosis. Consequently, CBM 588 modified gut microbiome and increased the butyric acid and oleic acid content. These lipid metabolic modifications induced GPR activation, which is a trigger of ERK 1/2 signaling and directed differentiation of downstream immune cells in the host colon tissue. Moreover, endogenous protectin D1 modified the gut microbiome, similar to CBM 588. This is the first study to report that CBM 588 influences the interrelationship between colon tissue and the gut microbiome through lipid metabolism. These findings provide insights into the mechanisms of prevention and recovery from inflammation and the improvement of host metabolism by CBM 588.

Clostridium butyricum Modulates the Microbiome to Protect Intestinal Barrier Function in Mice with Antibiotic-Induced Dysbiosis.

Project description:Clostridium butyricum MIYAIRI 588 (CBM 588) is a probiotic bacterium that has previously been used to prevent antibiotic-associated diarrhea. However, the underlying mechanism by which CBM 588 protects the gut epithelial barrier remains unclear. Here, we show that CBM 588 increased the abundance of Bifidobacterium, Lactobacillus, and Lactococcus species in the gut microbiome and also enhanced the intestinal barrier function of mice with antibiotic-induced dysbiosis. Additionally, CBM 588 significantly promoted the expansion of IL-17A-producing γδT cells and IL-17A-producing CD4 cells in the colonic lamina propria (cLP), which was closely associated with changes in the intestinal microbial composition. Additionally, CBM 588 plays an important role in controlling antibiotic-induced gut inflammation through upregulation of anti-inflammatory lipid metabolites such as palmitoleic acid, 15d-prostaglandin J2, and protectin D1. This study reveals a previously unrecognized mechanism of CBM 588 and provides new insights into gut epithelial barrier protection with probiotics under conditions of antibiotic-induced dysbiosis.

Clostridium butyricum MIYAIRI 588-Induced Protectin D1 Has an Anti-inflammatory Effect on Antibiotic-Induced Intestinal Disorder.

Project description:Metabolites are thought as the end products in cellular regulatory processes and their levels show the strongest relationships with the phenotype. Previously, we showed that the administration of Clostridium butyricum MIYAIRI 588 (CBM 588) upregulated protectin D1, an anti-inflammatory lipid metabolite, in colon tissue under antibiotic therapy. However, how CBM 588 induces protectin D1 expression and whether the metabolite has anti-inflammatory effects on antibiotic-induced inflammation are unclear. Therefore, here, we evaluated the effect of CBM 588 on lipid metabolism and protectin D1 in gut protection from antibiotic-induced intestinal disorders. In the CBM 588 treatment group, expression levels of genes encoding lipid receptors related to the conversion of DHA to protectin D1, such as polyunsaturated fatty acid (PUFA) receptors, G-protein coupled receptor 120 (GPR120), and 15-lipoxygenase (LOX), were increased in colon tissue. CD4+ cells producing interleukin (IL)-4, the main component of T helper type 2 (Th2) cells that can activate 15-LOX, also increased in CBM 588-treated groups even after clindamycin co-administration. In addition, similar to CBM 588, exogenously administered protectin D1 reduced inflammatory cytokines, while IL-10 and TGF-β1, works as anti-inflammatory cytokines, were increased. Our data revealed that CBM 588 activated 15-LOX to enhance protectin D1 production by increasing IL-4-producing CD4+ cell population in the intestinal tract. Additionally, CBM 588-induced protectin D1 clearly upregulated IL-10-producing CD4+ cells to control antibiotic-induced gut inflammation. We provide new insights into CBM 588-mediated lipid metabolism induction for the treatment of gut inflammatory diseases.

Clostridium butyricum MIYAIRI 588 Increases the Lifespan and Multiple-Stress Resistance of Caenorhabditis elegans.

Project description:Clostridium butyricum MIYAIRI 588 (CBM 588), one of the probiotic bacterial strains used for humans and domestic animals, has been reported to exert a variety of beneficial health effects. The effect of this probiotic on lifespan, however, is unknown. In the present study, we investigated the effect of CBM 588 on lifespan and multiple-stress resistance using Caenorhabditis elegans as a model animal. When adult C. elegans were fed a standard diet of Escherichia coli OP50 or CBM 588, the lifespan of the animals fed CBM 588 was significantly longer than that of animals fed OP50. In addition, the animals fed CBM588 exhibited higher locomotion at every age tested. Moreover, the worms fed CBM 588 were more resistant to certain stressors, including infections with pathogenic bacteria, UV irradiation, and the metal stressor Cu2+. CBM 588 failed to extend the lifespan of the daf-2/insulin-like receptor, daf-16/FOXO and skn-1/Nrf2 mutants. In conclusion, CBM 588 extends the lifespan of C. elegans probably through regulation of the insulin/IGF-1 signaling (IIS) pathway and the Nrf2 transcription factor, and CBM 588 improves resistance to several stressors in C. elegans.

Effects of Clostridium butyricum on intestinal environment and gut microbiome under Salmonella infection.

Project description:Salmonellosis causes massive economic losses globally every year. Especially in poultry, numerous drug-resistant bacteria have emerged; thus, it is imperative to find alternatives to antibiotics. As a probiotic, Clostridium butyricum (C. butyricum) provides the latest strategy for inhibiting the proliferation of Salmonella. This study aimed to evaluate the effects of C. butyricum on intestinal environment and gut microbiome under Salmonella infection. In this study, we modeled the infection of Salmonella using specific pathogen-free (SPF) chicks and found that the use of C. butyricum directly reduced the number of Salmonella colonizations in the spleen and liver. It also alleviated the histopathological changes of the liver, spleen, and cecum caused by Salmonella Enteritidis (S. Enteritidis). In addition, S. Enteritidis increased the expression of pro-inflammatory IL-6 in the cecum on day 6 postinfection. Interestingly, we found that C. butyricum changed PPAR-γ transcript levels in the cecum on day 6 postinfection. Analysis of the chick gastrointestinal microbiome showed that Salmonella infection increased the relative abundance of Subdoligranulum variabile. Further analysis found that Salmonella challenge significantly reduced the relative abundance of Faecalibacterium prausnitzii and C. butyricum increased the relative abundance of anaerobic bacteria in the gut on day 6 postinfection. Moreover, early supplementation of C. butyricum restored the epithelial hypoxia in S. Enteritidis infection in chicks. The results suggest that C. butyricum restores epithelial hypoxia caused by S. Enteritidis, improves the stability of intestinal flora, and inhibits the proliferation of Salmonella.

Gut microbiota dynamics and fecal SCFAs after colonoscopy: accelerating microbiome stabilization by Clostridium butyricum.

Project description:BackgroundColonoscopy is a classic diagnostic method with possible complications including abdominal pain and diarrhoea. In this study, gut microbiota dynamics and related metabolic products during and after colonoscopy were explored to accelerate gut microbiome balance through probiotics.MethodsThe gut microbiota and fecal short-chain fatty acids (SCFAs) were analyzed in four healthy subjects before and after colonoscopy, along with seven individuals supplemented with Clostridium butyricum. We employed 16S rRNA sequencing and GC-MS to investigate these changes. We also conducted bioinformatic analysis to explore the buk gene, encoding butyrate kinase, across C. butyricum strains from the human gut.ResultsThe gut microbiota and fecal short-chain fatty acids (SCFAs) of four healthy subjects were recovered on the 7th day after colonoscopy. We found that Clostridium and other bacteria might have efficient butyric acid production through bioinformatic analysis of the buk and assessment of the transcriptional level of the buk. Supplementation of seven healthy subjects with Clostridium butyricum after colonoscopy resulted in a quicker recovery and stabilization of gut microbiota and fecal SCFAs on the third day.ConclusionWe suggest that supplementation of Clostridium butyricum after colonoscopy should be considered in future routine clinical practice.

Fiber supplementation protects from antibiotic-induced gut microbiome dysbiosis by modulating gut redox potential.

Project description:Antibiotic-induced gut dysbiosis (AID) is a frequent and serious side effect of antibiotic use and mitigating this dysbiosis is a critical therapeutic target. We propose that the host diet can modulate the chemical environment of the gut resulting in changes to the structure and function of the microbiome during antibiotic treatment. Gut dysbiosis is typically characterized by increases in aerobic respiratory bacterial metabolism, redox potential, and abundance of Proteobacteria. In this study, we explore dietary fiber supplements as potential modulators of the chemical environment in the gut to reduce this pattern of dysbiosis. Using defined-diets and whole-genome sequencing of female murine microbiomes during diet modulation and antibiotic treatment, we find that fiber prebiotics significantly reduced the impact of antibiotic treatment on microbiome composition and function. We observe reduced abundance of aerobic bacteria as well as metabolic pathways associated with oxidative metabolism. These metatranscriptomic results are corroborated by chemical measurements of eH and pH suggesting that fiber dampens the dysbiotic effects of antibiotics. This work indicates that fiber may act as a potential therapeutic for AID by modulating bacterial metabolism in the gut to prevent an increase in redox potential and protect commensal microbes during antibiotic treatment.

Long-term dysbiosis and fluctuations of gut microbiome in antibiotic treated preterm infants.

Project description:Postnatal acquisition of the microbiome is critical to infant health. In preterm infants, empiric use of antibiotics is common, with significant health consequences. To understand the influence of antibiotics on acquisition of the microbiome over time, we longitudinally profiled microbial 16S rRNA in the stool of 79 preterm infants during their hospitalization in the intensive care unit and compared antibiotic treated and untreated infants. Despite similar clinical presentation, antibiotic treated infants had strong deviations in the content, diversity, and most dramatically, temporal stability of their microbiome. Dysbiosis and fluctuations of microbiome content persisted long after antibiotic exposure, up to hospital discharge. Microbiome diversity was dominated by a few common bacteria consistent among all infants. Our findings may inform clinical practice related to antibiotic use and targeted microbial interventions aimed at overcoming the adverse influence of antibiotics on the microbiome of preterm infants at specific developmental time points.

The biotherapeutic Clostridium butyricum MIYAIRI 588 strain potentiates enterotropism of Rorγt+Treg and PD-1 blockade efficacy.

Project description:Immune checkpoint inhibitors (ICI) have been positioned as a standard of care for patients with advanced non-small-cell lung carcinomas (NSCLC). A pilot clinical trial has reflected optimistic association between supplementation with Clostridium butyricum MIYAIRI 588 (CBM588) and ICI efficacy in NSCLC. However, it remains to be established whether this biotherapeutic strain may be sufficient to heighten the immunogenicity of the tumor draining lymph nodes to overcome resistance to ICI. Herein, we report that supplementation with CBM588 led to an improved responsiveness to antibody targeting programmed cell death protein 1 (aPD-1). This was statistically associated with a significant decrease in α-diversity of gut microbiota from CBM588-treated mice upon PD-1 blockade. At the level of the tumor-draining lymph node, such combination of treatment significantly lowered the frequency of microbiota-modulated subset of regulatory T cells that express Retinoic Orphan Receptor gamma t (Rorγt+ Treg). Specifically, this strongly immunosuppressive was negatively correlated with the abundance of bacteria that belong to the family of Ruminococcaceae. Accordingly, the colonic expression of both indoleamine 2,3-Dioxygenase 1 (IDO-1) and interleukin-10 (IL-10) were heightened in mice with greater PD-1 blockade efficacy. The CBM588-induced ability to secrete Interleukin-10 of lamina propria mononuclear cells was heightened in tumor bearers when compared with cancer-free mice. Conversely, blockade of interleukin-10 signaling preferentially enhanced the capacity of CD8+ T cells to secrete Interferon gamma when being cocultured with CBM588-primed lamina propria mononuclear cells of tumor-bearing mice. Our results demonstrate that CBM588-centered intervention can adequately improve intestinal homeostasis and efficiently overcome resistance to PD-1 blockade in mice.

Succession in the gut microbiome following antibiotic and antibody therapies for Clostridium difficile.

Project description:Antibiotic disruption of the intestinal microbiota may cause susceptibility to pathogens that is resolved by progressive bacterial outgrowth and colonization. Succession is central to ecological theory but not widely documented in studies of the vertebrate microbiome. Here, we study succession in the hamster gut after treatment with antibiotics and exposure to Clostridium difficile. C. difficile infection is typically lethal in hamsters, but protection can be conferred with neutralizing antibodies against the A and B toxins. We compare treatment with neutralizing monoclonal antibodies (mAb) to treatment with vancomycin, which prolongs the lives of animals but ultimately fails to protect them from death. We carried out longitudinal deep sequencing analysis and found distinctive waves of succession associated with each form of treatment. Clindamycin sensitization prior to infection was associated with the temporary suppression of the previously dominant Bacteroidales and the fungus Saccinobaculus in favor of Proteobacteria. In mAb-treated animals, C. difficile proliferated before joining Proteobacteria in giving way to re-expanding Bacteroidales and the fungus Wickerhamomyces. However, the Bacteroidales lineages returning by day 7 were different from those that were present initially, and they persisted for the duration of the experiment. Animals treated with vancomycin showed a different set of late-stage lineages that were dominated by Proteobacteria as well as increased disparity between the tissue-associated and luminal cecal communities. The control animals showed no change in their gut microbiota. These data thus suggest different patterns of ecological succession following antibiotic treatment and C. difficile infection.
