Gut bacteria’s fatty acids may help keep Candida in check

Microbiota-targeted approaches that boost specific SCFAs could help prevent harmful Candida overgrowth in vulnerable people.

Gut worms in mother mice linked to stronger antiviral defenses in pups

Microbiota-derived molecules such as IPA may offer a way to strengthen early-life immunity against respiratory viruses.

Specific gut microbe makes sepsis deadlier in mice

Sangeribacter muris KT1-3 made sepsis deadlier by amplifying inflammation driven by TLR4.

Gut microbiota maturation may be linked to infection risk in preterm babies

Bacteria such as Enterococcus faecium and Limosilactobacillus reuteri are key in activating an immune receptor that boosts the activity of protective immune cells.

In mice, a ketogenic diet protects the lungs from sepsis via gut bacteria

Azelaic acid travels from the gut to the lungs, where it activates immune cells to reduce inflammation and protect the lungs.

From dysbiosis to long-term outcomes: Flavia Indrio wraps up PPPP 2026

Prof. Flavia Indrio reflects on the main take-home messages from the congress, which brought together 32 leading international experts in microbiota research, allergy, nutrition, gut-brain axis and lung disease.

When microbiomes turn risky: a one health view of infective competence

Paul Wilmes, University of Luxembourg, explores the concept of infective competence within a One Health framework.

Oral microbiota therapy rebuilds gut bacteria to prevent recurrent C. difficile infection

VOS, an FDA-approved oral microbiota therapy, has been shown to reduce infection risk compared to traditional fecal transplants. 

Specific gut microbes protect mice from deadly bacterial infections after flu

Segmented filamentous bacteria, or SFB, protect mice from these deadly infections by reprogramming specific immune cells in the lungs.
