How does the body defend it..

vitamin c is all that we need.Eat fruits that are rich in Vitamin C.Much better is natural than supplements.

And remember one thing our body needs also bad bacteria but not so much.

your body defends itself through your immune system. the primary line of defense is your skin, but after a foreign body such as bacteria or viruses enters your body then the immune system takes action.

With your immune system.

Antibodies or cytotoxic t-cells will bind to specific groups on the outside of the bacteria or viruses, or kill our own body cells that are infected with bacteria/virus which prevents their spreading. When binding the bacteria/viruses the antibodies or cytotoxic t-cells will carry out a number of functions that result in the death of the bacteria and inactivation of the virus.
