Definition
Antibiotic resistance refers to the ability of bacteria to survive and proliferate despite the presence of antibiotics that would normally inhibit their growth or kill them. This phenomenon occurs through evolutionary processes, such as natural selection, where resistant strains are favored and become more prevalent in a population over time.
Summary
Antibiotic resistance is a growing global health concern that arises when bacteria evolve to withstand the effects of antibiotics. This phenomenon is driven by natural selection, where bacteria that survive antibiotic treatment can reproduce and pass on their resistant traits. The misuse and overuse of antibiotics in healthcare and agriculture have accelerated this process, leading to more difficult-to-treat infections. The implications of antibiotic resistance are severe, resulting in increased healthcare costs, longer hospital stays, and higher mortality rates. To combat this issue, it is essential to promote responsible antibiotic use, enhance public awareness, and implement effective infection control measures. Understanding antibiotic resistance is crucial for ensuring effective treatment options for future generations.
