Fig. 1From: Gut microbiota response to antibiotics is personalized and depends on baseline microbiotaPhases of microbiota response to antibiotics. After antibiotic exposure, baseline microbiota undergoes an initial perturbation (phase 1), during which some taxa may completely disappear, while some new taxa may arise. Potential determinants of phase 1 include baseline microbiota, specifics of antibiotic exposure, and host factors (e.g., genetics and immunity). After completion of antibiotic treatment, the microbiota undergoes reorganization (phase 2), which could lead to full recovery to baseline, partial recovery towards baseline, or shift to a completely new state. The focus of this study is the role of baseline microbiota in regulating phase 1 after controlling for antibiotic exposuresBack to article page
