Diet switching quickly impacts the gut microbiota and immune system

Two weeks of dietary intervention are sufficient to influence host immunity, metabolism and gut microbiota composition.

Gut microbes may influence susceptibility to respiratory infections 

The results of a recent study reveal that the severity of respiratory infections depends at least in part on a complex interplay between the gut microbiota and the immune system.

Gut microbes may help ease gastrointestinal damage associated with aspirin use

The results of a recent study shed light on the effects of aspirin use on the gut microbiota. The findings may also inform therapies for aspirin-mediated gastrointestinal damage.

Breast milk establishes a ‘protective’ gut microbiota, promoting infant health

The findings of a recent study shed light on the role of complement proteins in breast milk and provide a mechanism through which breastfeeding may provide protection from certain bacterial…

Gut microbes can adapt to long-term antibiotic use

The findings of a recent study suggest that antimicrobial-resistance mutations in commensal bacteria can make the microbiota surprisingly resilient to antibiotics.

Microbial signature is associated with severity of ulcerative colitis in children

The findings of a recent study suggest that the gut microbiota contributes to alterations in the levels of metabolites associated with ulcerative colitis.

Gut metabolites may help to predict infection risk after liver transplant

The findings suggest that microbial metabolites can help to predict who is at increased risk of infection after liver transplant. The results may also help to inform microbiota-targeted therapies.

How microbial ‘social networks’ shape host health

Socially transmissible microbes may influence human health and play a hidden role in social evolution.

Some gut microbes may boost a child’s brain development

By examining the gut-brain-microbiota axis in typical neurodevelopment, the findings could pave the way for identifying biomarkers for cognition and brain development.

A diverse gut microbiota prevents infection by blocking nutrient access

The findings of a recent study shed light on why gut microbiota diversity protects against infection. The results may also inform the design of pathogen-resistant microbial communities.
