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.

This study shows that phage T4 resistance mutations in E. coli create a genetic background that promotes β-lactam resistance.

This study assesses eight predicted defence systems in E. coli NILS69 against 93 phages, finding only PD-T4-3 and RM systems restrict phage infection.

The paper designs gene overlaps to stabilize synthetic circuits in E. coli by preventing loss-of-function mutations through evolutionary constraints.
