Drug-resistant bacteria
Antibiotic-resistant bacteria are microorganisms that have evolved mechanisms to withstand the effects of antibiotics, rendering these drugs ineffective in treating infections. This phenomenon, known as antimicrobial resistance (AMR), poses a significant global public health threat, leading to prolonged illnesses, increased mortality, and higher healthcare costs. Resistance can develop through genetic mutations or acquisition of resistance genes from other bacteria, often exacerbated by antibiotic overuse or misuse.
