Antibiotics: Dr Jekyll and Mr Hyde

Undoubtedly one of the most important scientific discoveries of the 20th century, antibiotics save millions of lives each year. However, their effectiveness is now under threat from the appearance of multiple drug resistance. By destroying the bacteria responsible for infection, antibiotics can also lead to dysbiosis. Spotlight on a therapeutic weapon to be handled with care.

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

What is the World Antimicrobial Awareness Week?

Each year, since 2015, the WHO organizes the World Antimicrobial 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.
