  • New Research on Maintaining Complex Gut Microbiota in Mouse Models

    An increased interest in studies involving the microbiota requires animal models that appropriately mimic the extremely complex normal gut microbiota. Differences in rodent models can have a negative impact on a study’s reproducibility. On July 4, 2018, researchers at the University of Missouri, University of California, Davis, and University of North Carolina at Chapel Hill […]

  • Upcoming Webinar: Cyclical Bias and Variability in Microbiome Research

    While developing a novel gnotobiotic housing strategy, researchers on the Nested Isolation project discovered a cyclical bias in the microbiome composition of animals in SPF cages. These changes in microbiota could influence phenotype and confound study endpoints, with implications for the reproducibility of some gnotobiotic research. How can you best identify and control for cyclical […]

  • A single genetic change in gut bacteria alters host metabolism

    Scientists have found that deleting a single gene in a particular strain of gut bacteria causes changes in metabolism and reduced weight gain in mice, according to a study in the journal eLife. The research provides an important step towards understanding how the microbiome – the bacteria that live in our body – affects metabolism. […]

  • Data to Insights: Addressing Challenges of the Microbiome

    A mysterious, complex and largely unknown universe exists within and on you. Every day, as you go about your routine, colossal quantities of microbes that form your unique microbiome are aiding or obstructing your functions. What role can this universe, the human microbiome, play in preventing disease and treating illness? This question has spurred unique […]

  • Limitations of Feces as Proxy for Gut Microbiota

    A myriad of factors can influence the gut microbiota composition of laboratory rats and mice: diet, stress, circadian rhythm, vendor source, how they are housed, and more. Since different gut microbiota compositions can elicit different phenotypes under otherwise similar experimental conditions, understanding what shapes the rodent microbiome is becoming increasingly important for researchers. Husbandry-Induced Microbiome […]

  • Feed Your Gut Microbiota for Improved Health

    Clostridium difficile is a significant source of infectious disease death in the United States, and C. difficile infection can be difficult to treat. Many researchers are focusing on new therapies for this major health problem, including clinical use of fecal microbiota transplantation. Dietary manipulations are another avenue of study. Researchers at the Stanford University School […]

  • Commensal microflora-induced T cell responses mediate progressive neurodegeneration in glaucoma

    ABSTRACT Glaucoma is the most prevalent neurodegenerative disease and a leading cause of blindness worldwide. The mechanisms causing glaucomatous neurodegeneration are not fully understood. Here we show, using mice deficient in T and/or B cells and adoptive cell transfer, that transient elevation of intraocular pressure (IOP) is sufficient to induce T-cell infiltration into the retina. […]

  • Neonatal selection by Toll-like receptor 5 influences long-term gut microbiota composition

    ABSTRACT Alterations in enteric microbiota are associated with several highly prevalent immune-mediated and metabolic diseases1,2,3, and experiments involving faecal transplants have indicated that such alterations have a causal role in at least some such conditions4,5,6. The postnatal period is particularly critical for the development of microbiota composition, host–microbe interactions and immune homeostasis7,8,9. However, the underlying […]

  • Treatment with camu camu (Myrciaria dubia) prevents obesity by altering the gut microbiota and increasing energy expenditure in diet-induced obese mice

    ABSTRACT Objective The consumption of fruits is strongly associated with better health and higher bacterial diversity in the gut microbiota (GM). Camu camu (Myrciaria dubia) is an Amazonian fruit with a unique phytochemical profile, strong antioxidant potential and purported anti-inflammatory potential. Design By using metabolic tests coupled with 16S rRNA gene-based taxonomic profiling and faecal […]

  • High Dose Vitamin D supplementation alters faecal microbiome and predisposes mice to more severe colitis

    ABSTRACT Vitamin D has been suggested as a possible adjunctive treatment to ameliorate disease severity in human inflammatory bowel disease. In this study, the effects of diets containing high (D++, 10,000 IU/kg), moderate (D+, 2,280 IU/kg) or no vitamin D (D−) on the severity of dextran sodium sulphate (DSS) colitis in female C57Bl/6 mice were investigated. […]

  • A Polysaccharide Isolated from Dictyophora indusiata Promotes Recovery from Antibiotic-Driven Intestinal Dysbiosis and Improves Gut Epithelial Barrier Function in a Mouse Model

    ABSTRACT Despite the tremendous biological activity of polysaccharides from the mushroom Dictyophora indusiata, its role in the restoration of gut microbiota has not yet been explored. The present study aimed to investigate whether D. indusiata polysaccharide (DIP) could modulate the recovery of gut microbiota composition and intestinal barrier function after broad-spectrum antibiotic-driven dysbiosis. Alteration and […]

  • Standardization in host–microbiota interaction studies: challenges, gnotobiology as a tool, and perspective

    ABSTRACT Considering the increasing list of diseases linked to the commensal microbiota, experimental studies of host–microbe interactions are of growing interest. Axenic and differently colonized animal models are inalienable tools to study these interactions. Factors, such as host genetics, diet, antibiotics and litter affect microbiota composition and can be confounding factors in many experimental settings. […]

  • Complementary intestinal mucosa and microbiota responses to caloric restriction

    ABSTRACT The intestine is key for nutrient absorption and for interactions between the microbiota and its host. Therefore, the intestinal response to caloric restriction (CR) is thought to be more complex than that of any other organ. Submitting mice to 25% CR during 14 days induced a polarization of duodenum mucosa cell gene expression characterised […]

  • Gut microbiota modulation accounts for the neuroprotective properties of anthocyanins

    ABSTRACT High-fat (HF) diets are thought to disrupt the profile of the gut microbiota in a manner that may contribute to the neuroinflammation and neurobehavioral changes observed in obesity. Accordingly, we hypothesize that by preventing HF-diet induced dysbiosis it is possible to prevent neuroinflammation and the consequent neurological disorders. Anthocyanins are flavonoids found in berries […]

  • Early cellular responses of germ-free and specific-pathogen-free mice to Francisella tularensis infection

    ABSTRACT Bacteria that are highly virulent, expressing high infectivity, and able to survive nebulization, pose great risk to the human population. One of these is Francisella tularensis, the etiological agent of tularemia. F. tularensis is a subject of intense scientific interest due to the fact that vaccines for its immunoprophylaxis in humans are not yet […]
