NewsAntibiotic-resistant bacteria found in many healthy birthing mothers and their newborns
A recent study found gut bacteria resistant to common antibiotics in a sizable percentage of healthy birthing mothers and their newborns. In this study, 38% of bacterial strains resistant to ceftriaxone transmitted from mother to infant were E. coli.

NewsNew gut-brain discovery offers hope for treating ALS and dementia
Scientists have identified a link between gut bacteria and the deterioration of the brain in Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD). The researchers discovered that certain bacterial sugars cause immune responses that kill cells—and how to prevent it.

News‘Hidden’ bugs in our gut appear key to good health, finds global study
A single group of bacteria has repeatedly shown up in high numbers in the gut microbiomes of healthy people. Scientists found the level of CAG-170 bacteria present was consistently higher in healthy people than those with diseases including inflammatory bowel disease, obesity and chronic fatigue syndrome.

NewsTaxiing through the gut: Formic acid in the microbiome
Scientists have found that the gut bacterium Blautia luti produces formic acid (formate) instead of carbon dioxide (CO₂) and hydrogen, with hydrogen bound to CO₂. In this case, formic acid is the electron taxi, allowing the energetically costly production of hydrogen to be bypassed.

NewsGut microbe–derived butyrate activates immune cells to enhance vaccine efficacy
Researchers have uncovered a new mechanism showing how butyrate—a short-chain fatty acid produced by gut commensal bacteria—enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.

NewsResearchers urge focus on child obesity and gut health to reduce risk of diabetes
Researchers are calling for more study of obesity, gut bacteria and metabolic conditions that arise in childhood and adolescence, with an eye to curbing the global rise of type 2 diabetes.

NewsHigh consumption of ultraprocessed foods may be linked to cancer survivors’ risk of death
Cancer survivors who consumed higher amounts of ultraprocessed foods as part of their diet had a significantly increased risk of both all-cause and cancer-specific death, a new study shows.

NewsVaping zebrafish suggest E-cigarette exposure disrupts gut microbial networks and neurobehavior
Researchers hope to spark broader public discussion on the health risks of e-cigarettes and provide scientific evidence to support a reassessment of existing regulations.

NewsGut bacteria may tip the balance between feeding tumors and fueling immunity
A new study reveals how bacteria in the gut can help determine whether the amino acid asparagine from the diet will feed tumor growth or activate immune cells against the cancer.

FeaturesGut microbiome and obesity: what we know - and what we don’t
Dysbiosis is defined as an imbalance in the composition and function of the gut microbiota. This imbalance can lead to dysregulated interactions within the bacterial community and between microbes and the host, and it can be associated with disease states. However, discussions of dysbiosis often rely on simplified dichotomies, such ...

NewsGlowing bacterial sensors detect gut illness in mice before symptoms emerge
Researchers have engineered gut bacteria that dim their fluorescent glow in the presence of illness. Their findings could improve how we diagnose problems in the gut by using bacteria that already live there.

NewsFecal microbiota transplantation improves response to immunotherapy in advanced kidney cancer
A new study provides compelling evidence that fecal microbiota transplantation (FMT) can enhance the effectiveness of immunotherapy in patients with advanced metastatic renal cell carcinoma (mRCC).
-
NewsInnovative ‘poop pills’ show promising results in clinical trials for multiple types of cancer
Fecal microbiota transplants (FMT), can dramatically improve cancer treatment. One study shows that the toxic side effects of drugs to treat kidney cancer could be eliminated with FMT. A second suggests FMT is effective in improving the response to immunotherapy in patients with lung cancer and melanoma.

NewsWild blueberries: New review explores benefits for heart, metabolism and the microbiome
A new scientific review summarizes the growing body of research on wild blueberries and cardiometabolic health, which includes factors like blood vessel function, blood pressure, blood lipids and blood sugar. It highlights the gut microbiome as a likely contributor to the cardiometabolic effects.

NewsStudy sheds new light on what drives evolution of gut microbiomes
A study of wild African herbivores offers new insight into how environmental conditions – not just diet and anatomy – can influence the evolution of gut microbes that play a critical role in animal health and well-being.

NewsMore than just gut cohabitants: how gut bacteria control immune responses
Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. The study reveals a new way in which the gut microbiome can influence the human body and may help explain how changes in gut bacteria contribute to inflammatory diseases.

NewsMore investigations needed into Wumei Pills-Lactobacillus Reuteri-intestinal stem cell axis for chemotherapy-Induced mucositis
A new letter appraising a recent study suggests the reported benefits of WMP and Lactobacillus reuteri in chemotherapy-induced mucositis are promising, but stronger causal and analytical foundations are needed.

NewsNew research suggests gut bacteria may be linked to memory decline in mild cognitive impairment and Alzheimer’s disease
A new review is shedding light on the growing evidence that gut microbiome imbalances—known as dysbiosis—may play a key role in the development and progression of mild cognitive impairment (MCI) and Alzheimer’s disease.

NewsTwo days of oatmeal reduce cholesterol level - thanks to impact on gut microbes
A short-term oat-based diet appears to be surprisingly effective at reducing the cholesterol level. The diet apparently influenced the composition of microorganisms in the gut. The metabolic products, produced by the microbiome, appear to contribute significantly to the positive effects of oats.

NewsExpert consensus on clinical applications of fecal microbiota transplantation for chronic liver disease
To assist clinicians in rapidly mastering and standardizing the clinical application of FMT for chronic liver disease, an expert consensus has been developed to address key aspects of FMT application and provide reference and guidance for clinical practice.
