Insights

Antibiotic overuse in newborns harms gut microbiota and health. This review explores these impacts and discusses microbiome-based solutions for infant gut health restoration.

Area of Science:

  • Microbiology
  • Neonatal Health
  • Pharmacology

Background:

  • Antibiotic therapy is crucial for bacterial infections but overuse, particularly in the perinatal period, poses risks.
  • Neonatal antibiotic exposure can lead to antibiotic resistance and gut dysbiosis.
  • These alterations negatively impact infant health and long-term well-being.

Purpose of the Study:

  • To review the influence of antibiotic treatment on the neonatal gut microbiota.
  • To summarize the subsequent negative health effects on infants.
  • To analyze microbiome-based strategies for restoring healthy neonatal gut microbiota.

Main Methods:

  • Literature review of recent evidence.
  • Synthesis of findings on antibiotic impact on neonatal gut microbiota.
  • Analysis of potential therapeutic interventions.

Main Results:

  • Antibiotic use in neonates significantly alters gut microbiota composition and function.
  • These alterations are linked to increased risk of infections, allergies, and metabolic disorders.
  • Early-life antibiotic exposure contributes to the development of antibiotic resistance.

Conclusions:

  • Antibiotic administration during the neonatal period has profound and lasting effects on the gut microbiome.
  • Restoring a healthy gut microbiota is essential for mitigating negative health outcomes in infants.
  • Microbiome-based interventions show promise for preventing and treating antibiotic-induced dysbiosis in neonates.
