Mouth bacteria may trigger rheumatoid arthritis flare-ups

The findings of a new study suggest that periodontal disease may contribute to rheumatoid arthritis by triggering specific immune responses.

Diet and environment drive the diversity of the infant gut virome

The findings of a new study suggest that infants acquire their gut virome from their diet and environment rather than from their mothers.

Pregnancy-induced changes to the gut microbiota may exacerbate inflammation

The findings of a new study reveal a microbe-immune axis that is disrupted in pregnant animals, suggesting potential therapeutic approaches for pregnancy-associated sepsis.

Maternal immune cells influence a newborn’s lung immunity through the microbiota

The findings of a new study suggest that a newborn’s lung immunity is influenced by the interplay between maternal γδ T cells, the gut microbiota and microbial-derived SCFAs.

The maturation of gut fungal communities is associated with a baby’s body mass index

The findings of a new study suggest that mycobiome maturation and infant growth trajectories are linked.

Microbiota signature linked to chronic fatigue syndrome

The findings of two recent studies published in Cell Host & Microbe may help to develop new diagnostic tools and better animal models of ME/CFS.

New analysis refutes the existence of a fetal microbiota

The findings of a new study support the ‘sterile womb’ hypothesis and may help scientists avoid pitfalls of contamination in the analysis of samples where microbes are expected to be…

How some gut microbes can promote obesity

The findings of a new study indicate that gut commensals may contribute to obesity through the overproduction of microbe-derived lipids.

Microbial signature may help identify women at risk for gestational diabetes

The findings of a new study suggest that biomarkers such as the gut microbiota composition may help develop diagnostics and therapeutic approaches for gestational diabetes.

How some gut bacteria avoid immune surveillance

The immune system tolerates flagellins of commensal bacteria while mounting an immune response against flagellins produced by pathogens.
