Now online! Nutrient competition predicts gut microbiome restructuring under drug perturbations
Nutrient competition predicts gut microbiome restructuring under drug perturbations
Systematic profiling of 707 drugs on their impact on stool-derived microbial communities shows that nutrient competition explains and predicts species shifts under drug treatment and that post-drug recovery is driven by ecological interactions like extinction and strain swapping.
