Antibiotics are medicines designed to fight bacterial infections by killing bacteria or stopping their growth. They target specific parts of bacterial cells, such as their cell walls or protein production, without harming human cells. This helps the immune system clear the infection more effectively.
However, misuse and overuse of antibiotics can lead to antibiotic resistance, where bacteria evolve to survive these drugs. This makes infections harder to treat and increases the risk of spreading resistant bacteria. Understanding how antibiotics work and using them responsibly is essential for maintaining their effectiveness and protecting public health. Shutdown123
