This study is testing whether a daily supplement containing probiotics and prebiotics (called synbiotics) can help prevent preterm birth in pregnant women at high risk. Researchers want to see if improving the balance of healthy bacteria in the vagina early in pregnancy can help …

This study aims to create a map of the normal bacteria and other tiny organisms that live on the surface of the eye. Researchers will observe 500 adults, some with healthy eyes and some with common eye conditions like glaucoma or macular degeneration. The goal is to understand ho…

This study aims to understand how two common over-the-counter mouthwashes affect the bacteria and viruses in your mouth and gut. Researchers will compare Listerine, Lumineux Oral Essentials, and plain water when used twice daily for about six months by 200 healthy young adults. T…

This study aims to understand how a hepatitis D treatment called bulevirtide affects gut bacteria and bile acids in patients. Researchers will follow 20 patients with hepatitis D and liver damage, collecting samples over 48 weeks to see how these gut factors change during treatme…
