New paper explores links among the diet, gut microbiota and health status.
Infants exposed to thirdhand smoke while hospitalized in the neonatal intensive care unit (NICU) show a difference in the composition of their gut microbiome, according to a new study by researchers with The University of Texas Health Science Center at Houston (UTHealth).

A phase II clinical trial shows that changing the gut microbiome through fecal transplant can transform cancer patients who never responded to immunotherapy into patients who do.
Scientists have discovered how a common virus in the human gut infects and takes over bacterial cells – a finding that could be used to control the composition of the gut microbiome, which is important for human health. The Rutgers co-authored research, which could aid efforts to engineer beneficial bacteria that produce medicines and fuels and clean up pollutants, is published in the journal Nature.
ILSI North America hosts Dr. Jaeyun Sung of the Mayo Clinic to discuss with participants the development of a gut microbiome-based health index.
Washington D.C. — Building consistent ways to measure intestinal processes can improve our understanding of how diet, nutrition and health interact. Three expert groups are converging to inform standards for characterizing the “gut microbiome” — the collection of bacteria and…
A study of the relationships between cognition and the gut microbiome of captive zebra finches showed that their gut microbiome characteristics were related to performance on a cognitive assay where they learned a novel foraging technique. Researchers also identified potentially critical bacteria that were relatively more abundant in birds that performed better on this assay. This correlation provides some of the first evidence of a relationship between a bird’s gut microbiome and its brain.
Liver failure – often due to acetaminophen overdose – is fatal in 80% of cases. The labs of Profs. Ido Amit and Eran Elinav discovered three liver-cell subsets that contribute to disease progression, and found that depleting the microbiome acts on those subsets to reduce liver damage and increase survival rates. The research may lead to treatments for liver failure.
Toxicological Sciences features leading research in toxicology in the areas of biomarkers, environmental toxicology, and more in the September 2020 issue.
What causes some people to develop chronic diseases such as rheumatoid arthritis, cancer and metabolic syndrome while others stay healthy? A major clue could be found in their gut microbiome — the trillions of microbes living inside the digestive system that regulate various bodily functions.
New research in mice suggests a protein found predominately in white blood cells helps keep gastrointestinal bacteria in balance and may protect against metabolic disorders.
University of Illinois Chicago researchers have found associations among disrupted sleep, blood pressure and changes in the gut microbiome.The research aimed to determine whether 28-day period of disrupted sleep changed the microbiota in rats.
A longstanding theory has suggested that gastric bypass surgery may have unique, weight loss-independent effects in treating type 2 diabetes. But new research from Washington University School of Medicine in St. Louis indicates that weight loss after surgery, rather than the surgery itself, drives metabolic improvements, such as the remission of diabetes.
The August 2020 issue of Toxicological Sciences includes exciting advances in toxicology research. The edition features pieces on biotransformation, toxicokinetics, and pharmacokinetics; developmental and reproductive toxicology; and more.
A new study shows how chronic psychological stress leads to painful vessel-clogging episodes—the most common complication of sickle-cell disease (SCD) and a frequent cause of hospitalizations. The findings, made in mice, show that the gut microbiome plays a key role in triggering those episodes and reveals possible ways to prevent them. The research was conducted by scientists at Albert Einstein College of Medicine and published online today in Immunity.
Published in this month’s edition of Toxicological Sciences are articles on biotransformation, toxicokinetics, and pharmacokinetics; developmental and reproductive toxicology; nanotoxicology; and more.
Children with type 1 diabetes have a less desirable gut microbiome composition which may play a role in the development of the disease, according to new research published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Article title: Antibiotic exposure postweaning disrupts the neurochemistry and function of enteric neurons mediating colonic motor activity Authors: Lin Y. Hung, Pavitha Parathan, Prapaporn Boonma, Qinglong Wu, Yi Wang, Anthony Haag, Ruth Ann Luna, Joel C. Bornstein, Tor C. Savidge, Jaime…
A new study finds antibiotic exposure during crucial developmental periods in early childhood alters digestive tract nerve function and bacterial colonies. The study is published in the American Journal of Physiology-Gastrointestinal and Liver Physiology.

A 2003 hypothesis says Parkinson’s disease is caused by a gut pathogen that could spread to the brain through the nervous system. No evidence was found until now; researchers report for the first time a significant overabundance of a cluster of opportunistic pathogens in the PD gut.
A microbiome “fingerprint” method shows that an individualized mosaic of microbial strains is transmitted to the infant gut microbiome from a mother giving vaginal birth. The study analyzed existing metagenomic databases of fecal samples from mother-infant pairs and used a germfree mouse model.
Researchers from Washington University in St. Louis studied the gut microbiomes of wild apes in the Republic of Congo, of captive apes in zoos in the U.S., and of people from around the world and discovered that lifestyle is more important than geography or even species in determining the makeup of the gut microbiome.
Infants who were started on solid foods at or before three months of age showed changes in the levels of gut bacteria and bacterial byproducts, called short-chain fatty acids, measured in their stool samples, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.
A new literature review from scientists at George Washington University and the National Institute of Standards and Technology suggests that nutrition and diet have a profound impact on the microbial composition of the gut.
Article title: Distal colonic transit is linked to gut microbiota diversity and microbial fermentation in humans with slow colonic transit Authors: Mattea Müller, Gerben D.A. Hermes, Emanuel E. Canfora, Hauke Smidt, Ad A.M. Masclee, Erwin G. Zoetendal, Ellen E. Blaak From…
Scientists at Wake Forest School of Medicine have identified a dead probiotic that reduces age-related leaky gut in older mice. The study is published in the journal GeroScience.
A new study from Washington University School of Medicine in St. Louis sheds light on how human gut microbes break down processed foods — especially potentially harmful chemical changes often produced during modern food manufacturing processes.
