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.

‘Hidden’ bacteria could explain recurrent urinary tract infections

The findings of a recent study indicate that effective treatments for recurrent UTIs may require the ability to penetrate human tissues.

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.

Recurrent infections and estrogen can shape the urogenital microbiota

New research indicates that recurrent urinary tract infections and estrogen can shape the urogenital microbiota in ways that may protect against recurrent infections.

Imbalances in gut microbes linked to recurrent urinary tract infections

Recurrent UTIs are in part caused by alterations of the gut microbiota and different immune response to bacterial bladder colonization.

Drug halts C. difficile infection, promotes recovery of the microbiota after antibiotic treatment

Ebselen may protect from C. difficile-associated tissue damage and bolster recovery of the microbiota after antibiotic treatment.

Gut microbiota could inhibit the growth of antibiotic-resistant bacteria

A new study shows that interactions with the resident gut microbiota could suppress the proliferation and antibiotic-resistance evolution of superbugs.

Laxative abuse and other diarrhea-causing events could trigger C. difficile infection

A new study published in Nature Microbiology shows that the risk of colonization with C. difficile is highest during recovery from acute diarrhea.

Nose-dwelling bacterium contributes to a healthy nasal microbiota

Staphylococcus epidermidis contributes to a healthy nasal microbiota, likely by stimulating the production of antimicrobial molecules in the nose.

Mother’s gut microbes protect newborns from infection

A study in mice shows that part of maternal milk’s protective effects comes from the bacteria that reside in the mother’s gut.
