  • Language, numeracy and logic in microbiome science


    To deliver precision therapeutics, microbiome-based medicine will require precision of language, logic and numerical accuracy. Epidemiological lessons of the past suggest that attempts to link almost everything in modern life with the microbiome as a risk factor for disease, without rapprochement with plausible mechanisms, will generate controversy rather than consensus.

  • USF Health convenes first Microbiome Joint Workshop with University of Florida


    The University of South Florida and the University of Florida convened a Microbiome Joint Workshop at USF Health on May 28, with research presentations by basic scientists and clinician scientists from both universities. It was an important first step in working together to unravel how different microorganisms living in our guts, on our skin, and […]

  • EU biotech firms unite in pushing for ‘harmonised’ microbiome therapeutics regulation


    The Intestinal Microbiome-based Medicines European Task Group (IMM-ETG) involves Caelus Health, EnteroBiotix, Ferring Pharmaceuticals and Maat Pharma along with Pharmabiotic Research Institute (PRI). “The IMM-ETG has been established to contribute to a harmonised regulatory framework in Europe for the intestinal microbiome products based on the whole ecosystem,” said Dr. Luc Sterkman, CEO of Caelus Health. […]

  • Priorities for the next 10 years of human microbiome research


    Over the past decade, more than US$1.7 billion has been spent on human microbiome research. Major projects are under way in the United States, the European Union, China, Canada, Ireland, South Korea and Japan. This investment has confirmed the importance of the microbiome to human health and development. It is now known, for instance, that […]

  • The Human Microbiome Project expands the toolbox for studying host and microbiome interactions


    Results from three long-term studies following host and microbiome characteristics during pregnancy and preterm birth, inflammatory bowel disease, and prediabetes have expanded our understanding of how humans and microbes interact and the resulting consequences for our health. The studies were funded as part of a second phase of the National Institutes of Health’s Human Microbiome […]

  • Transportation Affects Gut Microbiome of Laboratory Mice


    Experimental controls are at the center of every quality experiment, and understanding the causes of microbiome variability is key to controlling for microbiome-related effects. Researchers that utilize murine models attempt to control for possible microbiome variability by ordering mice from the same vendor, using littermate controls, and employing co-housing strategies1. Given the ongoing research reproducibility […]

  • How Antibiotics Affect Your Microbiome


    The human gut microbiome is a complex, highly-evolved commensal community with an integral role in your response to disease and how well you maintain homeostasis. While commensal bacteria vary from person to person, a person’s specific microbiome should contain the same relative percentage of bacterial species over their lifespan. The balance of this community can […]

  • Do you know what’s in your water?


    Most researchers know the pain of trying and failing to replicate a published experiment. This can result from something as simple as a poorly written methods section, in which important experimental details have been omitted. Barnett and Gibson recently called out the importance of an in vivo experimental detail that is commonly left out and […]

  • Changes in the gut microbiome and fermentation products concurrent with enhanced longevity in acarbose-treated mice


    ABSTRACT BACKGROUND Treatment with the α-glucosidase inhibitor acarbose increases median lifespan by approximately 20% in male mice and 5% in females. This longevity extension differs from dietary restriction based on a number of features, including the relatively small effects on weight and the sex-specificity of the lifespan effect. By inhibiting host digestion, acarbose increases the […]

  • Dynamic and Asymmetric Changes of the Microbial Communities after Cohousing in Laboratory Mice


    SUMMARY Horizontal transmission of the microbiota between different individuals is widely used to normalize the microbiota in laboratory mice. However, little is known about the dynamics of microbial communities and the level of microbiota transmission after cohousing. We extensively analyzed the fecal microbiota in Jackson and Taconic C57BL/6 mice to study horizontal transmission after weaning. […]

  • High fat diet alters gut microbiota but not spatial working memory in early middle-aged Sprague Dawley rats


    ABSTRACT As the global population ages, and rates of dementia rise, understanding lifestyle factors that play a role in the development and acceleration of cognitive decline is vital to creating therapies and recommendations to improve quality of later life. Obesity has been shown to increase risk for dementia. However, the specific mechanisms for obesity-induced cognitive […]

  • Heterochronic faecal transplantation boosts gut germinal centres in aged mice


    DISCUSSION The composition of the commensal gut microbiota changes with age, which is linked with an increase in age-associated morbidities such as frailty2,4 and intestinal disorders30, but the cause of this shift in the gut microbial composition is unknown. Here we sought to determine whether there is a causal link between age-dependent changes in the […]

  • Human Gut Microbiota from Autism Spectrum Disorder Promote Behavioral Symptoms in Mice


    ABSTRACT Autism spectrum disorder (ASD) manifests as alterations in complex human behaviors including social communication and stereotypies. In addition to genetic risks, the gut microbiome differs between typically developing (TD) and ASD individuals, though it remains unclear whether the microbiome contributes to symptoms. We transplanted gut microbiota from human donors with ASD or TD controls […]

  • Loss of function dysbiosis associated with antibiotics and high fat, high sugar diet


    ABSTRACT The incidence of urinary stone disease (USD) has increased four-fold in 50 years. Oxalate, which is degraded exclusively by gut bacteria, is an important constituent in 80% of urinary stones. We quantified the effects of antibiotics and a high fat/high sugar (HFHS) diet on the microbial metabolism of oxalate in the gut. High and […]

  • Toll‐like receptor 2 and toll‐like receptor 4 responses regulate neutrophil infiltration into the junctional epithelium and significantly contribute to the composition of the oral microbiota


    ABSTRACT BACKGROUND Oral gingival tissue, especially the junctional epithelium (JE), is constantly exposed to sub‐gingival plaque. A key component of gingival health is the regulation of the number of neutrophils that migrate into the gingival crevice to counteract its harmful effects. This report investigates the contribution of innate defense receptors, Toll‐like receptor 2 (TLR), TLR4 […]

  • CD1d Modulates Colonic Inflammation in NOD2−/− Mice by Altering the Intestinal Microbial Composition Comprising Acetatifactor muris


    ABSTRACT AIMS NOD2 and CD1d play a key role in innate immunity by recognizing conserved molecular patterns of pathogens. While NOD2−/− and CD1d−/− mice display structural and functional alterations in Paneth cells, animal studies have reported no impact of NOD2 or CD1d deficiency on experimental colitis. NOD2 mutations increase the susceptibility to inflammatory bowel diseases […]

  • Does MHC heterozygosity influence microbiota form and function?


    ABSTRACT MHC molecules are essential for the adaptive immune response, and they are the most polymorphic genetic loci in vertebrates. Extreme genetic variation at these loci is paradoxical given their central importance to host health. Classic models of MHC gene evolution center on antagonistic host-pathogen interactions to promote gene diversification and allelic diversity in host […]
