Antimicrobial resistance (AMR) is the resistance of a microorganism to an antimicrobial medicine to which it was previously sensitive. It develops when a microorganism mutates or acquires a resistance gene. Resistant organisms (including bacteria, viruses, fungi, protozoa and helminths) are able to withstand attack by antimicrobial medicines such as antibiotics, antivirals and antimalarials, so that standard treatments become ineffective and infections persist and may spread to other people.Antibiotic resistance in the European Region
