What is the purpose of antibiotics?

Answer 1

The purpose of antibiotics is to treat bacterial infections and prevent the growth and replication of bacteria. Antibiotics work by either killing the bacteria directly (bactericidal) or by inhibiting their growth and reproduction (bacteriostatic). They are used to cure a variety of bacterial infections such as respiratory tract infections, urinary tract infections, skin infections, and more serious infections like pneumonia and sepsis. However, antibiotics are not effective against viral infections such as the common cold or flu.
