  • Nature Biotechnology Publication: Translating microbiome futures


    The publication of Translating microbiome futures is the culmination of more than a year’s work by Gaspar Taroncher-Oldenberg, Consultant in Residence at Global Engage and Susan Jones, Senior Editor at Nature Biotechnology. Together they spoke with close to 150 key opinion leaders in microbiome R&D, venture capital, and regulatory agencies. Then on May 23, 2018, […]

  • Mouse Microbiomes Are Mostly Inherited

    A mouse’s gut microbiome is, largely speaking, inherited and alters very little throughout multiple generations, according to a long-term study of caged wild mice published in Science today (October 25). While this vertical transmission predominates in the given experimental setup, the study also reveals that certain genera of bacteria could spread horizontally from cage to […]

  • Housing Systems for Rodents Used in Microbiome Research


    Gnotobiotic technology in laboratory animal science is the processes and systems employed for maintaining gnotobiotic and germfree (germfree) research animals. Through sterilization of feed and other husbandry supplies, and by housing in systems that completely protect the animals from the surrounding environment and human caretakers, the intent is to create and maintain animal models with […]

  • Webinar Q&A — Cyclical Bias


    In a recent webinar, Dr. Alexander Rodriguez-Palacios of Case Western Reserve University School of Medicine discussed a confounding influence on many common microbiome study endpoints uncovered in studies using the NesTiso system. The NesTiso system has been described in a previous publication1 and examined in an on-demand webinar. There were several outstanding questions submitted by […]

  • Bringing order to the ‘wild frontier’ of microbiome medicine


    I never thought I’d someday write the sentence, “I really enjoyed that FDA meeting.” But here I am doing just that. The topic of the meeting — regulatory implications of an emerging class of medicines to promote health by modulating the teeming microbial ecosystems that live inside each of us — may not sound like […]

  • Pancreatic Cancer Microbiome Suppresses Immune Responses


    Alterations in the microbiome have an acknowledged role in cancer pathology1,2. Earlier this year, however, researchers at New York University published a manuscript3 connecting the pancreatic microbiome to cancer progression. In this report, Pushalkar et al. demonstrate that the endogenous microbiome of the pancreas can drive immunosuppressive conditions in humans and mice, which creates a […]

  • Animal Husbandry in Microbiome Research: 2018 RIGOR & REPRODUCIBILITY SURVEY


    The directors of the NIH funded Digestive Disease Research Core Centers (DDRCC) are conducting a survey to examine the perceptions of how animal husbandry and experimental practices influence microbiome data variability. DDRCC In March 2018, representatives from six of the eighteen DDRCC gathered for their annual Midwest Alliance meeting to discuss the latest findings in […]

  • Toxoplasma gondii infection triggers chronic cachexia and sustained commensal dysbiosis in mice


    ABSTRACT Toxoplasma gondii is a protozoan parasite with a predation-mediated transmission cycle between rodents and felines. Intermediate hosts acquire Toxoplasma by eating parasite cysts which invade the small intestine, disseminate systemically and finally establish host life-long chronic infection in brain and muscles. Here we show that Toxoplasma infection can trigger a severe form of sustained […]

  • Enteric infection coupled with chronic Notch pathway inhibition alters colonic mucus composition leading to dysbiosis, barrier disruption and colitis


    ABSTRACT Intestinal mucus layer disruption and gut microflora modification in conjunction with tight junction (TJ) changes can increase colonic permeability that allows bacterial dissemination and intestinal and systemic disease. We showed previously that Citrobacter rodentium (CR)-induced colonic crypt hyperplasia and/or colitis is regulated by a functional cross-talk between the Notch and Wnt/β-catenin pathways. In the […]

  • Interactions between Roseburia intestinalis and diet modulate atherogenesis in a murine model

    ABSTRACT Humans with metabolic and inflammatory diseases frequently harbour lower levels of butyrate-producing bacteria in their gut. However, it is not known whether variation in the levels of these organisms is causally linked with disease development and whether diet modifies the impact of these bacteria on health. Here we show that a prominent gut-associated butyrate-producing […]

  • Effects of water decontamination methods and bedding material on the gut microbiota


    ABSTRACT Rodent models are invaluable to understanding health and disease in many areas of biomedical research. Unfortunately, many models suffer from lack of phenotype reproducibility. Our laboratory has shown that differences in gut microbiota (GM) can modulate phenotypes of models of colon cancer and inflammatory bowel disease. We and others have also shown that a […]

  • The impact of exercise training and resveratrol supplementation on gut microbiota composition in high‐fat diet fed mice


    ABSTRACT The aim of this study was to examine the effect of exercise training and dietary supplementation of resveratrol on the composition of gut microbiota and to test the hypothesis that exercise training and resveratrol can prevent high‐fat diet (HFD)‐induced changes in the gut microbiota. Mice fed a HFD supplemented with resveratrol (4 g/kg food) […]

  • Transmission modes of the mammalian gut microbiota

    ABSTRACT Mammals house a diversity of bacteria that affect health in various ways, but the routes by which bacterial lineages are transmitted between hosts remain poorly understood. We experimentally determined microbiota transmission modes by deriving 17 inbred mouse lines from two wild populations and monitoring their gut microbiotas for up to 11 host generations. Individual- […]

  • Non-invasive continuous real-time in vivo analysis of microbial hydrogen production shows adaptation to fermentable carbohydrates in mice


    ABSTRACT Real time in vivo methods are needed to better understand the interplay between diet and the gastrointestinal microbiota. Therefore, a rodent indirect calorimetry system was equipped with hydrogen (H2) and methane (CH4) sensors. H2 production was readily detected in C57BL/6J mice and followed a circadian rhythm. H2 production was increased within 12 hours after […]

  • Long-term intake of Lactobacillus paracasei KW3110 prevents age-related chronic inflammation and retinal cell loss in physiologically aged mice.

    ABSTRACT Age-related chronic inflammation is a major risk factor for the incidence and prevalence of age-related diseases, including infectious and neurodegenerative diseases. We previously reported that a lactic acid bacteria, Lactobacillus paracasei KW3110, activated macrophages and suppressed inflammation in mice and humans. In this study, we investigated whether long-term intake of heat-killed L. paracasei KW3110 […]

  • Dysregulated Microbial Fermentation of Soluble Fiber Induces Cholestatic Liver Cancer


    SUMMARY Dietary soluble fibers are fermented by gut bacteria into short-chain fatty acids (SCFA), which are considered broadly health-promoting. Accordingly, consumption of such fibers ameliorates metabolic syndrome. However, incorporating soluble fiber inulin, but not insoluble fiber, into a compositionally defined diet, induced icteric hepatocellular carcinoma (HCC). Such HCC was microbiota-dependent and observed in multiple strains […]
