Gut microbiome shifts may begin before Alzheimer’s symptoms appear

A narrative review links reduced SCFA-producing gut bacteria and altered microbial metabolism with Alzheimer’s disease, while early evidence suggests similar changes may appear before cognitive symptoms. Mediterranean, DASH, MIND, and prudent diets are associated with beneficial microbial profiles, but direct evidence connecting diet, the microbiome, and amyloid pathology remains limited.

New study tracks rapid spread of drug-resistant Shigella across England

A nationwide genomic epidemiology study involving a researcher from Kingston University has revealed that sexually transmitted Shigella sonnei is spreading faster, over greater geographic distances and with higher transmission intensity than non-sexually transmitted strains in England.

Evidence shows artificial sweeteners cannot be judged as a single group

This narrative review found that non-nutritive artificial sweeteners have compound-specific and context-dependent associations with gut microbiota, metabolism, and health-related outcomes. Evidence does not support treating all sweeteners as uniformly harmful or safe, with human findings often limited or inconsistent.

WashU study identifies shared target for a new diarrhea vaccine

The bacteria enterotoxigenic E. coli and Shigella together cause hundreds of millions of infections each year and are among the leading causes of diarrheal death, especially in children.

How the right diet could support the gut bacteria that matter most

This review examines how gut keystone bacteria shape microbiome stability, disease risk, and responses to diet. It highlights why better identification methods, experimental validation, and precision diet-probiotic strategies are needed to restore gut homeostasis.

Gut bacteria patterns help predict insulin resistance in type 2 diabetes, study finds

Researchers used 16S rRNA sequencing and machine learning to identify gut microbiome patterns associated with insulin resistance severity in people with type 2 diabetes. XGBoost models showed that specific bacterial genera, including Bacteroides and Faecalibacterium, help distinguish individuals with higher insulin resistance from healthy controls.

Prebiotic microcapsules deliver pterostilbene to the colon to alleviate ulcerative colitis

A team led by clinicians and engineers has wrapped the plant-derived polyphenol pterostilbene (PSB) into prebiotic alginate/resistant-starch microcapsules coated with chitosan and shown that oral administration dampens dextran-sulfate-sodium (DSS) colitis in mice.

Bacteria use density switch to balance virulence and growth

Pathogens are becoming more and more resistant to antibiotics. With the goal of developing new therapeutic approaches to treat bacterial infections more effectively in the future, researchers at the Karlsruhe Institute of Technology (KIT) and the Max Planck Institute in Marburg investigated the plague-related bacterium Yersinia enterocolitica.

Flies on dairy farms act as hidden carriers of superbugs and zoonotic threats

Researchers used deep metagenomic sequencing to trace zoonotic pathogens and antibiotic resistance genes from cow manure into the guts of muscid flies on a French dairy farm. Findings reveal that flies not only carry but may amplify dangerous microbes, underscoring public health risks.
