Antibiotic resistance occurs when bacteria evolve to survive the drugs designed to kill them, rendering standard treatments ineffective.This phenomenon is driven largely by the overuse and misuse of antibiotics in human medicine and agriculture.When bacteria are exposed to antibiotics, the susceptible ones die, leaving behind those with rare mutations that allow them to survive.These resistant survivors then multiply, passing their genetic advantages to subsequent generations.As a result, common infections that were once easily treated are becoming increasingly difficult to combat, posing a major threat to global public health.
