Collective protection drives human gut microbiota response to amoxicillin treatment.

Paul Lubrano, Mélanie Magnan, Caroline Steiner, André Birgy, Benoît Chassaing, Mélanie Deschasaux, Arnaud Gutierrez, Hugo C. Barreto, Claire Amaris Hobson, Sophie Magréault, Vincent Jullien, Mathilde Lescat, Olivier Tenaillon

This study examines how human gut microbiotas respond to amoxicillin treatment using an in vitro model, finding that initial community composition and antibiotic inactivation dynamics influence resilience and resistance selection.

Aging: an inevitable road toward gut microbiota pathoadaptation

Rita Melo-Miranda, Ana Pinto, Hugo C. Barreto, Catarina S. H. Jesus, Isabel Gordo, Iola F. Duarte, Ana Sousa

This study shows that even in healthy aging conditions, gut commensals acquire pathoadaptive traits, suggesting that aging increases selection for pathobionts regardless of colonization resistance.
