Review highlights the disruptive effects of antibiotics on gut flora integrity, suggesting protective recolonization with probiotics may mitigate resistance and secondary infections.

Key Points

To review the protective functions of normal gastrointestinal bacterial flora and assess how antibiotic-induced disruption compromises mucosal defenses and drives microbial resistance.
Synthesized clinical and physiological evidence regarding gut flora roles in enterocyte integrity, metabolic regulation, and barrier protection against invasive pathogens.
Evaluated the impact of antibiotic exposure, chemotherapy, and radiation on barrier function and pathogen overgrowth.
Examined therapeutic recolonization strategies using lactobacilli and nonpathogenic yeasts in hospital and clinical settings.
Antibiotic therapy disrupts gastrointestinal microflora, leading to compromised enterocyte integrity, pathogen overgrowth, toxin translocation, and heightened risk of life-threatening infections.
Antibiotic pressure facilitates the emergence and proliferation of multi-drug-resistant organisms, escalating risks in healthcare environments.
Recolonization with nonpathogenic yeasts or lactobacilli during periods of antimicrobial stress demonstrates efficacy in preserving microbial balance and preventing secondary hospital-acquired infections.
