Microbial genome functions explain metabolite-driven dysbiosis and Pseudomonas-associated ammonium toxicity in Hydra

Natchapon Srinak, Tim Lachnit, Laura Ulrich…·Jan Taubenheim

This study shows that specific metabolites can shift Hydra's microbiome composition and function, leading to ammonia toxicity and disease-like phenotypes.

Nutrition induced changes in the microbiota can cause dysbiosis and disease development

Tim Lachnit, Laura Ulrich, Fiete M. Willmer…·Peter Deines

The paper shows that diet-induced changes in the microbiota can cause dysbiosis and disease in Hydra, supporting the overfeeding hypothesis.
