Impact of antibiotics on the microbiota

Antibiotic treatment: a double-edged sword

💊 Antibiotics are invaluable tools for treating numerous bacterial infections. However, their prolonged use can profoundly disrupt the commensal microbiota, increasing the risk of subsequent bacterial and even fungal infections.

🦠 Once antibiotic treatment ends, the microbiota typically tends to returns towards its initial state. However, this recovery may prove incomplete, leading to long-lasting changes in species abundance, metabolic activity and antibiotic resistance levels.

🎯 This review, published in Nature Microbiology, delves into the mechanisms by which antibiotic therapy may facilitate subsequent infections, contribute to the overgrowth of resistant microorganisms, and introduces novel strategies aimed at mitigating the collateral damage attributed to antibiotics.
