Antimicrobial resistance

Antimicrobial resistance is the loss of effectiveness of treatments for micro-organisms such as bacteria, fungi and viruses. As organisms become resistant to more antimicrobials over time they can eventually become virtually untreatable – these are commonly referred to as “superbugs”.

Antimicrobial resistance (AMR) has become a hot topic of late, and the level of public interest and concern it generates means it will not be going away anytime soon.
