The Role of the Gut Microbiome in Urinary Tract Infections: A Narrative Review.

Background/objectives: Urinary tract infections (UTIs) represent a substantial health concern worldwide. Although it is known that the gut can act as a reservoir for UTI-causing pathogens, the exact role of the gut microbiome in developing UTIs remains unclear. This review aims to investigate the link between the gut microbiome and UTIs and whether gut dysbiosis increases the risk of getting a UTI.

Antibiotic-free vaginal microbiota transplant with donor engraftment, dysbiosis resolution and live birth after recurrent pregnancy loss: a proof of concept case study.

Background: Vaginal dysbiosis covers imbalances in the vaginal microbiota, defined by altered composition of bacteria, viruses, and fungi and is associated with euploid pregnancy losses, premature birth, infertility, or bacterial vaginosis. A large proportion of women who have vaginal dysbiosis do not experience any symptoms. Antibiotics are the traditional treatment, recently combined with local probiotics in some cases.
