Antibiotics
Antibiotics and antimicrobial agents are drugs or chemicals that are used to kill or hinder the growth of bacteria . Antibiotics specifically target bacteria for destruction while leaving other cells of the body unharmed. Under normal conditions, our immune system is capable of handling the germs that invade the body. Certain white blood cells known as lymphocytes protect the body against cancerous cells , pathogens (bacteria, viruses, parasites), and foreign matter.
