Question

list few differences between antibiotics and antibodies.

Answer 1

Antibodies are what your body produces in response to the presence of antigens (bacterial or viral surface structures). They merely assist your white blood cells in identifying and destroying invading microorganisms. 

Antibiotics are chemicals that work to destroy invading bacteria, usually by disrupting the outer cell wall and making it "leak" or by messing up the bacteria's metabolic processes. They are not produced by the body and have no effect on viruses.

Answer 2

Antibodies and antibiotics also differ in their mechanism of action: the way they kill pathogens and fight off infection. Antibodies produced in B cells bind to specific factors, called antigens, found on the pathogen. Once an antibody binds an antigen, the antibody triggers an activation of the immune system.
