Antibiotics: what impact on the microbiota and on our health?

Despite their undeniable usefulness in the fight against infections, antibiotics today pose serious public health challenges: their excessive and inappropriate use leads to the emergence of numerous resistances, which, in the long term, could eventually make them ineffective. Moreover, antibiotics can also destroy certain beneficial bacteria within our microbiota.

On the occasion of the World AMR Awareness Week organized each year by the WHO, the Biocodex Microbiota Institute makes a full review.

What is the World AMR Awareness Week?

Each year, since 2015, the WHO organizes the World AMR Awareness Week (WAAW), which aims to increase awareness of global antimicrobial resistance. 

Antimicrobial resistance occurs when bacteria, viruses, parasites and fungi change over time and no longer respond to medicines. As a result of drug resistance, antibiotics and other antimicrobial medicines become ineffective and infections become increasingly difficult or impossible to treat, increasing the risk of disease spread, severe illness and death.

Held on 18-24 November, this campaign encourages the general public, healthcare professionals and decision-makers to use antibiotics, antivirals, antifungals and antiparasitics carefully, to prevent the further emergence of antimicrobial resistance.
