Study discovers role for gut bacteria in host-pathogen competition for nutrients

Vanderbilt research shows that commensal gut microbes impact the host-pathogen competition for iron and has implications for therapeutic strategies aimed at preventing pathogens from acquiring essential nutrients.

Wenhan Zhu, PhD, recently received a research award from the G. Harold and Leila Y. Mathers Foundation.

Mathers Foundation award supports study of bacterial physiology

Vanderbilt’s Wenhan Zhu, PhD, has received a three-year award from the G. Harold and Leila Y. Mathers Foundation to support his research that aims to answer a fundamental question about bacterial physiology and engineer probiotics to improve gut inflammatory diseases.

Gut microbiota and lung fibrosis

Microorganisms residing in the gut influence the severity of lung fibrosis in mouse models, suggesting that modifying the gut microbiota may offer therapeutic benefit for patients.

Is drinking tea good for your gut?

Microbiome profiling of older Chinese adults showed that tea drinking changed the diversity and abundance of some bacteria in men but not women — effects that may contribute to a reduced risk of hypertension.
