Evaluating effects of antibiotics across preclinical models of the human gastrointestinal microbiota

This study evaluates how different antibiotics affect gut microbiota in two preclinical models, showing varied impacts across taxa and highlighting model-specific differences in antibiotic susceptibility.

Clostridioides difficile colonization is not mediated by bile salts and utilizes Stickland fermentation of proline in an in vitro model

This study shows that C. difficile colonization in an in vitro model is not dependent on bile salts but relies on proline fermentation via Stickland pathway, with context-dependent effects.
