The microbiome is a complex and dynamic ecosystem that contributes to host metabolism, immunity, and disease resistance. Infections represent major perturbations to this system, often disrupting microbial composition, diversity, and function. The resilience of the microbiome, its capacity to recover equilibrium after disturbance, is critical for restoring health and preventing long-term complications. Mechanisms of disruption include pathogeninduced inflammation, epithelial barrier damage, and secondary effects of antibiotics, leading to loss of colonization resistance and dysbiosis. Factors influencing resilience include host genetics, diet, environmental exposures, and the presence of microbial reservoirs. Recovery follows reproducible phases of succession, from initial restoration of diversity to the re-establishment of functional pathways. Case studies of bacterial, viral, and fungal infections illustrate variability in resilience, highlighting the importance of community context and infection severity. Emerging biomarkers, multi-omics approaches, and computational models are improving the measurement of resilience, while therapeutic strategies including dietary interventions, probiotics, fecal microbiota transplantation, and microbiome-informed drug development hold promise for enhancing recovery. Ethical and privacy considerations remain central as microbiome science advances. Understanding and promoting microbiome resilience after infection has profound implications for clinical practice, public health, and precision medicine.
