NewsGut microbiota plays a role in metabolic health after bariatric surgery
Changes in gut microbiota after bariatric surgery are strongly linked to altered metabolic health and sustained improvement in type 2 diabetes. A study shows changes in gut bacterial composition and function are associated with metabolic improvements, including insulin release and blood sugar control.

NewsMouse study suggests high-fat diets during pregnancy worsen severe GI illness in preterm babies
A new mouse study suggests a link between a high-fat prenatal diet and induction of potentially deadly symptoms of necrotizing enterocolitis (NEC) in premature babies.

NewsScientists discover how gut bacteria toxin invades colon cells to trigger cancer
A common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of the colon. Researchers have now shown that the B. fragilis toxin BFT must first bind host receptor claudin-4 before it can cause damage.

NewsThe Nexus of Food Systems, Ecosystems and Human Health: Sign up for our fascinating free webinar!
What if health is not produced by humans alone, but co-created with the ecosystems, organisms, and food systems we depend on? A fascinating free webinar will explore how microbes connect people to food systems and the ecosystems that undergird food production.

NewsHead impacts associated with altered gut microbiome in football players
Non-concussive head impacts—hits to the head that don’t cause clinically detectable symptoms—are correlated with subsequent changes to the gut microbiome in a small sample of US collegiate football players, according to a new study.
-
NewsEvolutionary processes shape bacterial populations in the human gut
Researchers used the ‘reverse ecology’ analytical approach to demonstrate that many known gut bacterial species consist of several evolutionarily distinct groups that have adapted to different conditions in the gut.

NewsGenetic ‘bonus material’ makes the gut bacterium Segatella copri oxygen-tolerant
Researchers have found that some strains of the gut bacterium Segatella copri possess bonus material that makes them more oxygen tolerant. The presence of the molecular regulator OxyR is crucial for this. The team discovered that strains carrying OxyR are particularly prevalent in industrialized regions of the world.

NewsCaesarean birth: sex-specific effects on the microbiota
A research team investigating microbial colonisation in early life set out to understand how delivery mode and sex interact over the course of development, and whether this interaction could affect susceptibility to intestinal diseases such as colitis in adulthood.

NewsGut microbes actively support immunity in people living with HIV
A new study shows that gut microbes help bolster immunity in people living with HIV – and that, one day, these microbes may be harnessed to protect this population from infections driven by immune deficiency.

NewsDisease-causing pathogen rewires gut metabolism to secure nutrients for growth
Enterotoxigenic Bacteroides fragilis (ETBF), which causes diarrhea and has been implicated in colitis and colorectal cancer, uses a toxin it produces to reprogram intestinal cell metabolism and generate conditions that support its growth.

News“Tell me who your friends are, and I’ll tell you who you are”
New research reveals that when microbes live together, they can sense one another and actively reduce competition by shifting toward different roles instead of all doing the same thing. It shows that microbes do not just respond to their environment, they respond to each other.

NewsFrom gut to brain: scientists engineer bacteria to treat severe liver-related brain dysfunction
In vivo studies showed that programmable “living medicines” could reduce brain toxins and prevent neurological symptoms of hepatic encephalopathy, offering distinct advantages over a widely prescribed antibiotic.

NewsLifestyle, diet, and clinical factors shape the gut microbiome in cancer patients
Lifestyle factors, such as physical activity and dietary modifications can beneficially modulate the gut microbiome of cancer patients - however their effects are often shaped by non-modifiable variables.

NewsScientists pinpoint the changes that happen when gut bacteria invade the bloodstream
Researchers have pinpointed genotypic and phenotypic changes that take place when colonising bacteria in a patient’s gut invade and infect the bloodstream. The team aimed to determine what changes occur within bacteria in a patient’s gut that enable them to become invasive bloodstream pathogens.

CareersFrom microbial processes to biofilm control: our interview with LAM deputy editor Marciane Magnani
We catch up with food microbiologist Professor Marciane Magnani of the Federal University of Paraíba in Brazil who has just been appointed as a Deputy Editor of Letters in Applied Microbiology.

NewsThe brain–gut health initiative: A pioneering effort in psychiatric research
Researchers analyze brain imaging data, microbiome profiles, and clinical assessments to identify biomarkers for precision mental healthcare. The Brain–Gut Health Initiative is an ongoing long-term clinical study designed to investigate how interactions between the brain and gut microbiome contribute to psychiatric disorders.

NewsFrom precision intervention to a “virtual gut”: how close are we to predicting and steering the human microbiome?
A new review maps how multi-omics and machine learning could turn host-microbiome research from correlation hunting into actionable prediction and personalized therapy.

NewsGut microbiota impacts resistance to bacterial pneumonia: Study
A gut-lung connection influences susceptibility to infection by Acinetobacter baumannii, according to a new study. Investigators found that antibiotics disrupt the gut microbiota, suppress protective immune system pathways in the lungs; and increase the severity of pneumonia.

NewsIntestinal Candida albicans is associated with subclinical coronary atherosclerosis in metabolic dysfunction-associated steatotic liver disease with cirrhosis
Researchers have published the first report of gut fungal dysbiosis associated with the severity of metabolic dysfunction-associated steatotic liver disease and subclinical coronary atherosclerosis. An increased abundance of fecal C. albicans was observed in patients with cirrhosis and high SCA burden.

NewsYellow food coloring changes gut microbiome in early life
Researchers found that the gut microbiotaof young rats changed with exposure to acceptable daily intake levels of the food coloring tartrazine. The males showed increases in bacteria linked to low-grade inflammation and they also did not gain as much weight as was expected.
