Microecological Interventions against Antibiotic-Induced Dysbiosis and Related Resistome Expansion

Abstract: Antibiotic exposure and the emergence of antimicrobial resistance are critical global health threats, with antibiotic-induced gut dysbiosis contributing to increased mortality, prolonged illness, and significant economic burden. This review introduces the complex interplay between antibiotic exposure, gut microbiota dysbiosis, and the dissemination of antimicrobial resistance genes, which collectively undermine intestinal barrier function and promote systemic inflammation. It also explores how microbial metabolites influence resistance mechanisms through metabolic regulation, alteration of bacterial communities, antibiotic biotransformation, biofilm formation, and host-microbe interactions. Microecological interventions-including probiotics, prebiotics, synbiotics, postbiotics, fecal microbiota transplantation, dietary modifications, and emerging strategies-have the potential to restore microbial homeostasis, enhance colonization resistance to invading pathogens, and mitigate the spread of resistant pathogens. By integrating ecological and therapeutic perspectives, these approaches offer a sustainable framework for combating antibiotic resistance and improving clinical outcomes.
