Antibiotic use can harm the gut microbiome, leading to adverse health effects. This review introduces "microbiotoxicity" to help clinicians balance antibiotic risks and benefits.
Area of Science:
- Microbiology
- Pharmacology
- Clinical Medicine
Background:
- Antibiotic use is linked to antimicrobial resistance and microbiome dysregulation.
- Microbiome alterations are associated with adverse health outcomes.
- This review examines recent evidence on antibiotic impacts on the microbiome.
Approach:
- Analysis of recent interventional studies.
- Inclusion of germ-free mouse models and human volunteer studies.
- Consideration of a phase III microbiome-based medicine trial.
Key Points:
- Growing evidence links antibiotics to microbiome perturbation.
- Further causal evidence is needed to fully understand these effects.
- The term 'microbiotoxicity' is proposed to describe antibiotic-induced microbiome harm.
Conclusions:
- Clinicians must weigh the risks of microbiotoxicity against antibiotic benefits.
- A framework is suggested for prescribers to evaluate these risks.
- Understanding antibiotic-mediated microbiome effects is crucial for patient care.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
