PATHOLOGY

Detailed explanation-1: -Some, such as penicillin, kill bacteria by destroying the bacterial cell wall. Others, such as tetracycline, interfere with the ability of bacteria cells to reproduce or make proteins or nutrients they need to survive.

Detailed explanation-2: -There are two main ways in which antibiotics target bacteria. They either prevent the reproduction of bacteria, or they kill the bacteria, for example by stopping the mechanism responsible for building their cell walls.

Detailed explanation-3: -Only bacterial infections can be killed with antibiotics. The common cold, flu, most coughs, some bronchitis infections, most sore throats, and the stomach flu are all caused by viruses. Antibiotics won’t work to treat them.
