Antimicrobial Resistance
Antimicrobial resistance is the biological phenomenon by which microorganisms — including bacteria, viruses, fungi, and parasites — evolve the capacity to withstand the drugs designed to eliminate them, rendering standard treatments ineffective and allowing infections to persist and spread.
Overview
Resistance arises through mechanisms including genetic mutation, horizontal gene transfer, and selective pressure imposed by the overuse or misuse of antimicrobials, producing strains colloquially known as superbugs. The phenomenon exemplifies Darwinian natural selection operating on accelerated timescales, offering a real-world model of evolutionary dynamics observable within years rather than millennia.
Why it matters
The World Health Organization identifies antimicrobial resistance as one of the foremost global public health threats of the twenty-first century, with drug-resistant infections already attributable to millions of deaths annually. Critically, it undermines the foundational safety of modern medicine: routine surgeries, chemotherapy, and organ transplantation all depend on effective antimicrobials to prevent secondary infections, placing the therapeutic advances of the past century in jeopardy.
