Researchers from Stanford University published a paper in Science titled “Seasonal cycling in the gut microbiome of the Hadza hunter-gatherers of Tanzania” which examines the relationship between diet, seasons, and the microbiome. The authors performed a longitudinal study on 350 stool samples collected throughout a year and a half and found that the microbial population […]

Here are the first few microbiome conferences of next year: Phage Futures Congress The […]
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, […]
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 […]
Two extraordinary young scientists honored with prizes and more than $100,000 in support for research into the impacts of microbial communities on human health Hilden, Germany, and Germantown, Maryland, October 17, 2018 – QIAGEN today announced the winners of its fifth annual 2018 Microbiome Awards, a competition for outstanding researchers working on diverse aspects of […]
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 […]
Submissions to the uBiome Clinical Outcomes in Microbial Genomics Innovation Challenge are now open, welcoming applications from healthcare providers, students, trainees, and researchers worldwide. Winning proposals will receive grants which include access to uBiome’s clinical testing kits, as well as microbiome sequencing and bioinformatics services. “uBiome is thrilled to further expand our collaborations in the […]
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 […]
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 […]
ABSTRACT Dysbiosis of the intestinal microbiota has been shown to result in altered immune responses and increased susceptibility to infection; as such, the state of the intestinal microbiome may have profound implications in the perioperative setting. In this first-in-class study, we used 16s ribosomal RNA sequencing and analysis in a mouse model of general anesthesia […]
ABSTRACT Epidemiological studies have shown that children born by cesarean section (CS) are at higher risk of developing chronic inflammatory diseases, and it has been suggested that a skewed gut microbial colonization process early in life and altered priming of the immune system are causative. The aim of this study was to clarify whether impaired […]
ABSTRACT Experiencing psychosocial adversities in early life such as maternal seperation (MS) increases the risk of psychiatric disorders. Immune-inflammatory responses have imperative roles in the pathophysiology of psychiatric disorders. MS relatively changes the composition of intestinal microbiota leading to an overactivation of the hypothalamic–pituitary–adrenal (HPA) axis, and subsequently increases the corticosterone level. In this study, […]
ABSTRACT 1 Background Commensal flora are involved in the appropriate development of the mature immune system. However, it is unclear how commensal flora contribute to immune responses against periodontal pathogens, including the response to lipopolysaccharide (LPS). The purpose of this study was to evaluate the expression of immune responses after topical application of LPS in […]
ABSTRACT Chronic prostatitis/Chronic pelvic pain syndrome (CP/CPPS) is a common syndrome with limited therapies and an unknown etiology. Previously, our laboratory has defined a potential role for pathogenic infection in disease onset. Intra-urethral infection with a uropathogenic Escherichia coli strain isolated from a CP/CPPS patient, CP1, induces prostatic inflammation and tactile allodynia in mice. We […]
ABSTRACT Organoids generated from pluripotent stem cells are used in the development of organ replacement regenerative therapy by recapitulating the process of organogenesis. These processes are strictly regulated by morphogen signalling and transcriptional networks. However, the precise transcription factors involved in the organogenesis of exocrine glands, including salivary glands, remain unknown. Here, we identify a […]
SUMMARY Nutritional supplementation with probiotics can prevent pathologic bone loss. Here we examined the impact of supplementation with Lactobacillus rhamnosus GG (LGG) on bone homeostasis in eugonadic young mice. Micro-computed tomography revealed that LGG increased trabecular bone volume in mice, which was due to increased bone formation. Butyrate produced in the gut following LGG ingestion, […]
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 […]
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 […]
Significance Studies using experimental models have indicated that multiple sclerosis (MS)-like disease can be triggered in the gut following interactions of brain autoimmune T lymphocytes with local microbiota.
Gnotobiotics, edited by Trenton Schoeb and Kathryn Eaton, is invaluable to those developing or managing gnotobiotic facilities.
Brigham Young University: We all know that a poor diet is unhealthy, but a new BYU study finds that stress may just as harmful to our bodies as a really bad diet.
Abstract For more than three decades it has been recognized that small amounts of vector saliva can significantly alter the infectivity of vector-borne pathogens and subsequent in vivo dynamics.
Abstract Mouse models have enabled breakthroughs in our understanding of the immune system, but it has become increasingly popular to emphasize their shortcomings when translating observations to humans.
