What does "antibiotic resistance" mean?

The term "antibiotic resistance" specifically refers to the ability of bacteria or other microorganisms to withstand the effects of antibiotics that were once effective in treating infections caused by them. This resistance can develop through various mechanisms, including genetic mutations or acquisition of resistance genes from other bacteria. When bacteria become resistant, standard antibiotic treatments may no longer be effective, leading to more severe infections, prolonged illness, and increased risk of transmission to others.

Understanding this concept is essential, especially in the context of public health, as antibiotic resistance poses a significant challenge in treating bacterial infections. It underscores the importance of appropriate antibiotic use, as overprescription and misuse can accelerate the development of resistance among bacteria.
