Antimicrobial resistance refers to the ability of microorganisms, such as bacteria and fungi, to resist the effects of antibiotics or other medications that are designed to kill them. This occurs when these microorganisms evolve mechanisms to survive exposure to drugs that were previously effective in killing them. As a result, common infections become more difficult to treat, and may lead to increased morbidity and mortality rates among patients who contract such infections. Antimicrobial resistance is a growing global health concern, as it threatens the effectiveness of many medical interventions that rely on antibiotics or other antimicrobial agents for treatment.
