Project description:BackgroundLimosilactobacillus reuteri (earlier known as Lactobacillus reuteri) is a well-studied lactic acid bacterium, with some specific strains used as probiotics, that exists in different hosts such as human, pig, goat, mouse and rat, with multiple body sites such as the gastrointestinal tract, breast milk and mouth. Numerous studies have confirmed the beneficial effects of orally administered specific L. reuteri strains, such as preventing bone loss and promoting regulatory immune system development. L. reuteri ATCC PTA 6475 is a widely used strain that has been applied in the market as a probiotic due to its positive effects on the human host. Its health benefits may be due, in part, to the production of beneficial metabolites. Considering the strain-specific effects and genetic diversity of L. reuteri strains, we were interested to study the metabolic versatility of these strains.ResultsIn this study, we aimed to systematically investigate the metabolic features and diversities of L. reuteri strains by using genome-scale metabolic models (GEMs). The GEM of L. reuteri ATCC PTA 6475 was reconstructed with a template-based method and curated manually. The final GEM iHL622 of L. reuteri ATCC PTA 6475 contains 894 reactions and 726 metabolites linked to 622 metabolic genes, which can be used to simulate growth and amino acids utilization. Furthermore, we built GEMs for the other 35 L. reuteri strains from three types of hosts. The comparison of the L. reuteri GEMs identified potential metabolic products linked to the adaptation to the host.ConclusionsThe GEM of L. reuteri ATCC PTA 6475 can be used to simulate metabolic capabilities and growth. The core and pan model of 35 L. reuteri strains shows metabolic capacity differences both between and within the host groups. The GEMs provide a reliable basis to investigate the metabolism of L. reuteri in detail and their potential benefits on the host.

Project description:Background and Objectives: Lactobacillus reuteri DSM 17938 (L. reuteri) is a probiotic that can colonize different human body sites, including primarily the gastrointestinal tract, but also the urinary tract, the skin, and breast milk. Literature data showed that the administration of L. reuteri can be beneficial to human health. The aim of this review was to summarize current knowledge on the role of L. reuteri in the management of gastrointestinal symptoms, abdominal pain, diarrhea and constipation, both in adults and children, which are frequent reasons for admission to the emergency department (ED), in order to promote the best selection of probiotic type in the treatment of these uncomfortable and common symptoms. Materials and Methods: We searched articles on PubMed® from January 2011 to January 2021. Results: Numerous clinical studies suggested that L. reuteri may be helpful in modulating gut microbiota, eliminating infections, and attenuating the gastrointestinal symptoms of enteric colitis, antibiotic-associated diarrhea (also related to the treatment of Helicobacter pylori (HP) infection), irritable bowel syndrome, inflammatory bowel disease, and chronic constipation. In both children and in adults, L. reuteri shortens the duration of acute infectious diarrhea and improves abdominal pain in patients with colitis or inflammatory bowel disease. It can ameliorate dyspepsia and symptoms of gastritis in patients with HP infection. Moreover, it improves gut motility and chronic constipation. Conclusion: Currently, probiotics are widely used to prevent and treat numerous gastrointestinal disorders. In our opinion, L. reuteri meets all the requirements to be considered a safe, well-tolerated, and efficacious probiotic that is able to contribute to the beneficial effects on gut-human health, preventing and treating many gastrointestinal symptoms, and speeding up the recovery and discharge of patients accessing the emergency department.

Project description:The term probiotic refers to bacteria that provide a beneficial effect to the host. Limosilactobacillus reuteri (Lactobacillus reuteri) is a probiotic isolated from human breast milk. Although L. reuteri has antimicrobial and anti-inflammatory activities occasionally linked to anti-aging effects, there are no reports of the effects of L. reuteri on longevity. This study evaluated the anti-aging effects of L. reuteri on the lifespan and physiology of Drosophila melanogaster. L. reuteri increased the mean lifespan of fruit flies significantly without reducing the reproductive output, food intake, or locomotor activity. Furthermore, the data suggested that the longevity effect of L. reuteri is mediated by the reduction of the insulin/IGF-1 signaling pathway and the action of reuterin, an antimicrobial compound produced by L. reuteri. These results show that L. reuteri can be used as a probiotic that acts as a dietary restriction mimetic with anti-aging effects.

Project description:Probiotics have been proposed as a potential strategy for managing ulcerative colitis (UC). However, the underlying mechanisms mediating microbiota-host crosstalk remain largely elusive. Here, we report that Limosilactobacillus reuteri (L. reuteri), as a probiotic, secretes cytoplasmic membrane vesicles (CMVs) that communicate with host cells, alter host physiology, and alleviate dextran sulfate sodium (DSS)-induced colitis. First, L. reuteri-CMVs selectively promoted the proliferation of the beneficial bacterium Akkermansia muciniphila (AKK) by upregulating the expression of glycosidases (beta-N-acetylhexosaminidase and alpha-N-acetylglucosaminidase) involved in glycan degradation and metabolic pathways and restored the disrupted gut microbiota balance. Second, L. reuteri-CMVs were taken up by intestinal epithelial cells (IECs), elevated the expression of ZO-1, E-cadherin (Cdh1), and Occludin (Ocln), decreased intestinal permeability, and exerted protective effects on epithelial tight junction functionality. RNA sequencing analysis demonstrated that L. reuteri-CMVs repaired intestinal barrier by activating the HIF-1 signaling pathway and upregulating HMOX1 expression. Third, L. reuteri-CMVs increased the population of double positive (DP) CD4+CD8+ T cells in the intestinal epithelial layer, suppressing gut inflammation and maintaining gut mucosal homeostasis. Finally, L. reuteri-CMVs exhibited satisfactory stability and safety in the gastrointestinal tract and specifically targeted the desired sites in colitis mice. Collectively, these findings shed light on how L. reuteri interact with the host in colitis, and provide new insights into potential strategies for alleviating colitis.

Project description:Limosilactobacillus reuteri is a beneficial bacterium that inhabits the gastrointestinal tract of different mammals. Diverse beneficial effects have been attributed to specific strains, in part mediated by the production of reuterin. Here, we report the draft genome sequence of L. reuteri INIA P572, a reuterin-producing strain isolated from pig feces.

Project description:Evaluating the safety of probiotic microorganisms is an important part of the development of probiotic products. In this study, we have performed a systematic safety assessment of Limosilactobacillus reuteri American Type Culture Collection (ATCC) PTA 4659 based on genome analysis, antibiotic susceptibility testing, phenotypic characterization, and a human clinical safety study. Genome sequence analysis showed that the strain is free from virulence and antibiotic resistance genes. Connected to this, phenotypic characterization showed that the strain is susceptible to the main classes of antibiotics. Limosilactobacillus reuteri ATCC PTA 4659 was shown to produce histamine, which has previously been described as an anti-inflammatory mediator produced by certain L. reuteri strains. However, the amount of histamine, a biogenic amine, poses no safety concern of a potential product. The strain was investigated in a human clinical safety study and was shown to survive passage through the gastrointestinal tract, both when administered at high [1 × 1011 colony-forming units (CFU)/day] and low doses (1 × 109 CFU/day). The clinical safety evaluation showed that the doses administered are safe for human consumption. Furthermore, carbohydrate utilization, mucus adhesion, and tolerance to acid and bile were studied. It was shown that L. reuteri ATCC PTA 4659 has a very high adhesion to mucus and tolerance to both gastric pH and bile, all potentially important properties for a probiotic strain. Altogether, this study has demonstrated that Limosilactobacillus reuteri ATCC PTA 4659 is safe for human consumption and along with its phenotypic characteristics and previously described anti-inflammatory effects, makes it a promising strain for future probiotic development.
