The effects of antibiotic use on gastrointestinal function

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• The gastrointestinal (GI) tract harbors a complex bacterial flora essential for enterocyte integrity, metabolic and immunologic functions, and pathogen defense.
• Disruption of gut flora by antibiotics, infection, chemotherapy, or radiation compromises the protective barrier, leading to pathogen overgrowth, toxin translocation, and severe infections.
• Antibiotic use drives antimicrobial resistance, a significant public health concern.

Purpose of the Study:

• To highlight the critical role of gut microbiota in health and disease.
• To underscore the negative consequences of gut flora disruption.
• To explore the potential of beneficial microbial interventions.

Main Methods:

• Review of existing literature on gut microbiota and its disruption.
• Analysis of the impact of antibiotics and other stressors on gut flora.
• Evaluation of therapeutic strategies involving beneficial microorganisms.

Main Results:

• Gut flora disruption leads to impaired barrier function and increased susceptibility to pathogens.
• Antibiotic resistance is exacerbated by the widespread use of antibiotics.
• Interventions using nonpathogenic yeasts or lactobacilli demonstrate potential in managing patients with compromised gut flora.

Conclusions:

• Maintaining gut flora integrity is vital for preventing infections and managing antibiotic resistance.
• Probiotic interventions show promise in restoring gut health during therapeutic interventions.
• Further research into microbial therapies is warranted for clinical application.
