Antibiotics have revolutionized modern medicine, saving countless lives. However, their repeated or inappropriate use profoundly disrupts the gut microbiota, reducing its diversity and protective capacity. This dual aspect of therapeutic progress and microbial imbalance highlights the need for judicious use.

70 % of people claim to know that antibiotics impact the microbiome

35 % Only 1 in 3 people had been informed by a HCP that taking antibiotics could have negative consequences on the balance of their microbiota

To mark the WHO's annual World AMR Awareness Week, The Biocodex Microbiota Institute takes stock.

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.

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.

Repeated exposure to antibiotics can profoundly disrupt the balance of the microbiota, leading to dysbiosis with various clinical consequences. These alterations in the microbiota are now recognized as a risk factor in many diseases. Better understanding them means strengthening prevention and personalizing care.

The widespread and sometimes inappropriate use of antibiotics is making them less and less effective in treating infections, with many bacteria now resistant to antibiotics. Surveillance, research, and awareness remain essential to controlling this major health issue.

Microbiotalk: short conferences on antimicrobial resistance

This Microbiotalk conference aims to illuminate the multifaceted challenges of AMR, exploring the intricate connections between gut microbiota, environmental factors, and public health. Featuring international experts and patient advocates, the event delves into topics such as the impact of antibiotics on the intestinal microbiota, the emergence of resistance in early childhood, environmental reservoirs of resistant bacteria, and the critical role of patient and public engagement.

After antibiotic treatment, the microbiota takes time to regain its balance. Approaches based on understanding the interactions between antibiotics and intestinal flora are paving the way for new support strategies. This knowledge opens up promising prospects for maintaining a healthy microbiota and preventing post-treatment dysbiosis.
